What are some of the options that mimic the borla x pipe design and are available currently? I really want to ditch the rear cats but I dont want to deal with the 3" pipes on the corsa so I'd like something similar to the Borla design. Ive seen Manzo and AME (or something like that) but didnt see many reviews for them.

I have had the Manzo and Borla. For the money, Manzo is pretty hard to beat. Corsa does sound the best though.

Someone did a performance test and Corsa was worse than the Borla or a custom Titanium exhaust which did the best. The Manzo is similar dimensions to the Borla but the muffler side pipes are a bit smaller than needed. Someone mentioned using an exhaust expander to make it easier but I'm not knowledgeable about that.

I used a Top Speed Pro 1 x pipe. Fit good and sounds good too. Billy Boat makes one too.

Look for AWE x-pipe. Sounds good and I believe it is 2.75" pipe.

...or, Google speed shops in your area and have them build you a custom cat-back.

The new AWE x-pipe seems to be gaining some popularity.

See my/our comments here -- I'd recommend the Manzo or Top speed.

Whats wrong with the 3 inch?

I just installed the Corsa. No issues with it being 3". Everything fit like a glove. Sounds great. There is a post where a gentlemen said he did lose power from his stock exhaust during track runs and then put the stock exhaust back on and gained the few 10th of a second back. I was not in it for the power gain, just the sound. I do like the AWE and I probably would have given that a try if I had to do over. While my exhaust sounds much better than it did from stock, I still think B&B Fusion or Borla ATAK is in the future, once I win the lotto. No more mods for a while. I just need to enjoy the car at the moment.

Being the OEM exhaust system is 2.75 inch there have been some dyno suggestions that show a 3 inch X pipe with the stock exhaust does not pick up as much power as a 2.75 inch x pipe. One guy claimed track proven performance loss by going to the 3 inch on his Z06 and then gained his track times back after switching to the OEM X pipe. HE did provide time slips so its hard to argue with. Now the "power gains" with an X pipe are minimal on a Z06. Maybe 10 HP/TQ on a good day. There is also a suggestion that going with a 3 inch Xpipe causes a loss in low end torque due to scavenging efficiency being hampered. And this would be due to the exhaust pulses becoming less efficient escaping due to the pipe diameter change in the middle of the system with a 3 inch X pipe.

Now all of that said, there was a YouTube video where they dyno'd a Z06 and the Corsa(3inch) was the lowest power with Borla(2.75inch) being higher but not as good as the custom built titanium X pipe they were advertising in the video. I for one DO believe that the 3 inch Corsa negatively effects torque a small amount and DOES cause a disruption in exit exhaust gas pulses. But I have no real proof. Additionally were not talking a ton of power here so anyone who is just daily driving their vette and doesn't race likely won't even notice.

I still suggest staying with a 2.75 inch diameter X pipe whichever way you go. I was fortunate enough to have bought the Borla for my 2015 Z51 and then removed it before I traded it in and got my Z06 and then installed it on my Z06. Love the extra sound with it.

Corsa with Magnaflow Comps is a killer set up.

We can get you the Corsa or the AWE. We have both in stock!

Why wouldn't you just have an exhaust shop remove the rear cats vs buying and installing a whole new X-pipe mid-section without them? Seems cheaper and I'd bet the gains are similar. Or is there some other kind of restriction besides the rear cats in the OEM mid-pipe?

So that you can easily go back to stock.

It's pretty simple for them to install the straight pipe sections with clamps instead of welding and do a bit of a crimp on the catted sections so you can swap them back and forth too. Just curious if anyone has done that vs replacing the whole mid-pipe?

Internets_Ninja

The cost is so close to just buying an X pipe and not worrying about clamps and leaks. Why even bother with the headache? Not to mention you can easily sell the aftermarket X pipe down the road. And another thing, the factory X pipe uses a crossover vs aftermarket typically uses the better intersecting type like they use on NASCAR. The latter being better at making top end power.
