I just received my 2019 corvette 2LZ Z06 and I was wondering some quick/relatively inexpensive things I could do to upgrade the beast it already is. I know from a performance standpoint it’s very neglible but I was looking to get some good headers/xpipe and a new exhaust system. I loved the Borla ATAK I had on my old 2015 it was just a basic 2015 string Ray 2lz with nothing special

Hi Badger1991 ~ from all my reading, the vets are the same as all the other cars I've ever had and the most bang for the buck is typically an exhaust change. It instantly changes the car sound and depending what you change, it can give you a small or large HP bump, and there's tons of options from a few hundred dollars to a few thousand dollars. The problem is your car is new and has cat's in the header and another set further down in the pipes. Many of the exhaust mods that have HP increases delete one or both sets of cats which can pose a problem when you go to get your emissions sticker. If your annual mileage is under the state limits for emission inspection, then your fine to go wild with this mod. If HP increase isn't a requirement but you want to change the sound, just change out areas in the last segment of the exhaust where the mufflers are located...…. Good luck

Exhaust on Z06's is not the "most bang for your buck"... really far from it.

Factory cat back has guys running 1000whp through it... its not a restriction really.

Best bang for the buck is a pulley and a tune, although there goes your warranty.

Anything that really gives you any HP requires a tune...

I think the top 3 mods on the Z06 is: pulley, headers(or cat delete pipe's such as norcalss), and a CAI. CAI doesnt require a tune, but you wont gain much of anything with it. An X-pipe that gets rid of the secondary cats is also a top mod, but it really doesnt add any performance and the main cats in the headers are the bigger restriction. Pulley and headers requires a tune.

Mr. Gizmo

Does the corsa x-pipe remove the back set of cats?

timmyZ06

Yes the unmonitored rear cats.

As far as performance upgrades, rjacobs is right. Anything that will add power that you can actually feel, will very likely void your drivetrain warranty. I would be hesitant to do that with a brand new car, but some guys don't care about that, and dive into the performance mod ocean with the knowledge that they might get stuck with a hefty bill if something blows up. Just go into it with your eyes open.

A ported throttle body helps with throttle response. A BMS filter is an option to a cold air intake, with probably similar results. An X-pipe, which eliminates the secondary cats, or a cat-back exhaust system will give you better sound (maybe, depending on what sound you like). But it's unlikely that any of these mods will give you more than 10-20 rear wheel horsepower (if any), which, in a car this powerful, is statistically insignificant.

XPEL wrap is a high dollar item, but in my opinion is worth every penny.

My advice would be to drive it a while and get to know it before doing anything drastic. It already has more power than you can safely, or legally, use on the street.

I suggest an off road Xpipe like the Corsa or Borla if you can find one. A BMS filter as I think it’s as good as a CAI on a relatively stock car without a tune. A ported TB is a nice upgrade on an M7 as well as the MGW shifter. I know people have said the ported TB is noticeable on the auto as well. These mods will make it sound better as well as give it a better drivability. The little added HP is just a bonus.

Mr. Gizmo

yep thats the best advice -- drive it a couple thousand miles get to know the car before doing anything. I have had my 2017 M7 2lz m7 with PDR for about 17 months. Here are my thoughts.

They do run quite a bit better with some miles on them. the torque is outstanding. Its a different beast then the Ls7 which I liked alot, rather then wringing every last little bit of rpm out of like the Ls7, The Lt4 seems to do best when you let all the torque do the work between 3500 and 5800 rpm - I personally think the car is pretty amazing short shifting 1st at around 4500 rpm and letting 2nd exploit all the torque. Thats a huge amount of fun.

Skip the 100 bucks on the BMS filter. It might show results on the dyno, but I can't really tell much difference on the street and some of the speculation here is, after the car is running the BMS for a while the computer adjusts and any gains you see initially are offset after the ecm compensates for the change.

The biggest thing you can do is make sure the intercooler is purged and completely full. - mine was 2/3rds full and the car performed poorly. Most if not all of these cars leave the factory with out this being adequatley performed - because it takes time, - the factory does a half *** job filling it and turns the car loose.
Its takes a half a day plus procedure with the dealer tech that knows what they are doing and assuming they have right equipment to evacuate the system. My intercooler was only 2/3rds full causing the pump to cavitate - flipping something in the ECM pulling lots of power.

Traction control is very aggressive, much more so the the prior generation c5 and c6's. I think this fed quite a bit of my perception of the c7z being a bit of a dog.
The c7z runs best on warmer days with the tires bite with traction control off but active handling on. --

I personally think the c7z's are very conservatively tuned from the factory compared to the c5z and c6z. - The c7z would probably do well with just a slight tweak to lean it out just a C-hair with a Cold air intake, then the next step up would be going to the magnuson 2300 supercharger. But be careful with the magnuson, a member here bought the magnuson for his Lt1 grandsport, and it was defective, after some going back and forth magnuson did come through for him but it was a PIA for him.

In order here are my thoughts.
1. Drive it- put powerstop z26 pads on if you don’t track. They will save you hours of cleaning.
2. take it in for the 500 mile oil change, get the intercooler purged and filled and the alignment checked(Alignment is gratis) I went with the street alignment. mine was way off, others have corded their tires in 5 or 6k miles not dealing with this right away.
3. Corsa Xpipe. - as timmy z06 said that removes the downstream cats - so you would need a tune -- and that voids the warranty.
4. CAI - but that requires a tune and voids your warranty.
5. Magnuson 2300. - Some recommend going with a smaller pulley to spin the supercharger faster. That works too but I think spins a too small supercharger that already spins to fast generating too much heat even faster.

My suggestion is to make sure you have the break in miles and take your car to a HPDE day. You really do not know what the car is capable of until you drive it on a track. You might find you want to invest in tires and brake pads instead of bolt on’s that make the tires spin more. The car as is is a very capable machine.

To get more sound go to the center console screen and choose the settings icon and then select Engine Sound Management and set the exhaust in Track Mode. If you have an M7 the exhaust will be wide open all the time except when you put the drive mode in Eco and you get V4 operation. Anytime the engine is running in V4 mode it makes objectionable noises so they close the muffler valves when the engine is operating in V4 mode. If you have an A8 V4 mode can happen in all of the drive modes so you will hear the exhaust get quiet everytime the engine switches to V4 mode. The way to avoid that is to place the transmission in manual mode and use the paddles to shift.

As for performance mods don't do any until you can go to an HPDE at a track with long straights where you can push the Go Pedal to the floor for extended periods of time which will get you some prodigious speeds. If you can't hold the throttle open as long as others you have just found out you aren't ready for any more performance than you already have.

All I did was had the dealer put new brake pads on my 19Z06. Also had it paint correction, fully wrapped and ceramic coated. I’m not doing any mods for quite sometime. Just my opinion. My C5Z was all done up. Leaving this stock for now. It has plenty of power to get you into trouble. The Z06 from stock is a beast!!

thelastday

PTB and Halltech intake are very common bolt-on options that do add a bit of HP. Corsa x-pipe sounds great but not a lot louder outside of cold starts and WOT. Did you get an M7 or A8?

Hope you got a wheel warranty or have some cash saved for aftermarket wheels at some point.

mmjsport

I would do the Xpel on the front of the car and some ceramic coating. That will give the car some protection and shine. Also makes it easy to wash. Don't worry about performance mods yet like others said. Drive it for at least 500-1000 miles and get a good feeling for it. The car has an absurd amount of power already. The wheels do seem to be a common issue with everyone so I would recommend looking into quality aftermarket ones for the piece of mind. A 2LZ z06 is what I got as well as you know is between 90-100k depending on options. (Minus good discounts). I would recommend spending a few extra thousand on good wheels and keeping your OEM to put back on when you sell the car. You can sell the aftermarket and get some of that purchase back. Those are my .02 cents. I've had my baby for two weeks now and 900 miles. It's an addicting amount of fun and literally puts a smile on my face thats hard to wipe off. I'm gonna post my review on a separate thread on my next mods. Keep an eye out. Enjoy your baby and drive her! Having it parked is the worse thing to do, enjoy it as much as you can. Don't save it for the next guy. Have fun and be safe.

Badger1991, ours is hard to beat as a value Mod. Relatively inexpensive, super easy 15 min install, great driver's car feel, faster and smoother response, some HP at WOT, and not a warranty buster.

Many call this Mod transformative in that changes the character of the car for the better. Please, take a look.

Thanks,

tuantrang

Congrats on the new Z,
First thing i'll do is xpel the whole car, but for performance i don't know what route you like, i'll do Tsp header, a corsa helixx x pipe and a aprokavic titanium exhaust. Jake style Intake also<< can't forget jake,

Badger1991

Thanks for all the great advice. I really appreciate all the great feedback and advice. I will stick with keeping everything stock for now and then move on to the performance side once I get a full grasp on what she can do. I still want to try and make it a bit louder. I know borla no longer has there X pipe for the corvette, does anyone know of the corsa will bolt on and fit with the borla ATAK version.

The Z06 is a beast of the car right out of the factory. On the track, the stock exhaust system is music to the ear and absolutely fantastic .. I enjoy following the Z06 on the track. On the straightway it is like a rocket. I hardly see any car that can keep up with a stock Z06. Don't void your warranty, unless you have money to burn.

Borla still makes a x-pipe for the C7 Z06, here's a link to the newest version. cheers, Jacob

Badger1991

Hmmm I got off the phone with a Borla Specialist and he informed me there is no x pipe for the Z06. Was he just mistaken or is there something I am missing? Thank you for all the help. I can be a bit slow when it comes to making sure I get exactly what I need/what will work for my car.

Jacob Palmer

Now I’m second guessing myself! Hope that’s the right part (#60548) as I will be installing it on my Z07 Tuesday. Can anyone clear this up???
