I'll be installing a set of LG Pros this Saturday. Here are my concerns:

1. I've heard I should expect to get a CEL and codes thrown because the O2 sensors get relocated. Will a retune fix this?

2. Are the gaskets that come with the headers better than the OEM gaskets? I've heard they are similar if not the same in design.

3. I currently have Borla Sport (Stingers) installed. Will there be an increase in exhaust note? I don't care about it being louder just curious if it will be.

4. Will there be any noticeable HP gain?

My Vette is a 2006. The only other mod is a Hurricane air box.

Thanks for any and all replies.

 

I don't have LG's so I can't comment on the gaskets. What I can tell you is that the car will be louder and make about 30+ more HP. You should get a dyno tune to take advantage of the mods and make sure everything is in harmony.

 

Your cats will take longer to come up to temp because you've moved them farther downstream. It's common to set a code and get the CEL for the rear 02 sensors because of this. Some folks never see it...most do though.

You'll also experience some initial minor exhaust smell every time your start it until the cats come up to temp.

Your neighbor across the street can clear the code/s for you although it will come back eventually. He can also permanantly "tune out" those codes if you want although you really want to get a full tune.

One possibility on your tune to think about especially considering where you live and the lack of any local tuning expert...If you choose to go the "mailorder tune" route your neighbor has HP Tuners that can datalog your car for you and provide that file along with your factory tune. You can forward those two files to one of many forum vendors who offer the mailorder tune service. I think the going rate is about $150-$200 for that option. Charlie at RPM and Carlos are the first two that come to mind that offer the service. The beauty being you don't have to travel beyond your driveway to get it done!

Carlos' recent post on his service... http://forums.corvetteforum.com/c6-t...-help-you.html

Oh...forgot to mention you'd need to cover the cost of my two HP Tuner credits to license your VIN..about $100.00

Use your factory GM gaskets...best choice. Sound wise, slightly louder and a bit more mechanical noise but I think it's music to the ears..not noise.

Give "AWARE02" a shout...he's been down this path and will be glad to give you a few pointers.


Good morning neighbor!

 

I used GM gaskets....No issues at all and the headers have been off twice since the initial install.

I don't care what anyone says...get a custom dyno tune. Don't mess around with a mail order tune...If you are going to spend money, spend a little more and get the most out of your car........Yes, a tuner can eliminate your rear O2 codes.

Here are a couple vids of my car before my build with your same exhaust setup (LG LT's / Stingers). At the time of these vids, it only made 380 hp....But, you'll get the idea of how that exhaust combo sounds.

I bought pro's and just ended up going to my dealership and getting new OEM gaskets...now I just want my pro's to come

 

1. Yes it will probably throw a code, but a tune will fix that issue.
2. people choose to use the OEM gaskets.
3. The exhaust note will change.
4. There will be a hp gain, but this should be most noticeable after a tune.

 

I had to ask any problems passing a DE inspection with the headers?

 

I haven't had to run it through yet cause it's an 07, but I have heard from others that there is no issue DE as long as the O2 code is eliminated and not showing active or pending in the computer

 

 

A little eye candy.....

 

Thanks. Sorry OP...Good Luck with your setup....

 

Thanks neighbour! I'll get with you when you get back. I'm taking it to Karl's house on Sunday. He'll help me with the install.

 

Sitting at the hotel in Salzburg answering this.Woohoo! You'll be in good hands with Karl's help. He's done a few!

 

I hope you guys are having a great time. We finished up at 1400. We started at 1000. The install went real smooth. At idle there's not much difference in sound. At WOT she screams. Karl was a HUGE help. Your car is looking good. That red really shines in the sun. I'll see you when you get back and we'll get this thing tuned so I can take advantage of the extra HP.

 

I just turned off my rear O2 sensors becuase of the codes. And Yes I also used new OEM gaskets as well. No leaks for a year now.

 

4 hours total! Wow you guys were moving and things must have gone really straightforward! I'm sure Karl's Kwik-Lift was a big help also. Wish I could have been there but sounds like you didn't need me anyhow. We'll figure out the tune issue when I get back. You have lots of options though.

My Crystal Red Metallic looks a lot better clean. Had to drop it off at Karl's in the rain so the car is in serious need of a bath and detail job. Do me a favor and tell Karl to get right on that if you would. Also tell him two coats of Zaino will be just fine.

 

Enjoy the new power and sound

 

Ken, get off the CF, you are supposed to be on vacation!! Sorry no Zaino...just turtle wax... and it didn't even leave too many scatches!!

 

Turtle Wax? You get the extra chunky version right?...nothing but the best for your friends right?

Gotta check the forum you know!..even after 8hrs/500km through the Austrian, Italian and Bavarian Alps today! Started off snowing through the first two hours and then dropped to a clear and a million view down through the valleys in Italy. Took 8 hours for the route I chose! I think I paid the Italians about $25.00 in toll road fees and they had the worst roads of anywhere I've ever been. Anyhow, now sitting at Edelweiss downing my second beer for the evening while the wife hits the souvenir shop.

The rental car I have (diesel 5-speed wagon) has been knocking down about 500 miles to the gallon (correction...make that 500 kilometers per liter) give or take a few! It isn't going to win any drag races but man is it stingy at the pump.

The Garmin 770 I bought has been priceless!!

Zugspitze tomorrow...later.

 

I'm curious...

Why did you get headers if you didnt know if there would be a change in the exhaust note or a power increase?
