Has anyone done the C5 exhaust mod of switching to the C6 Z06/ZR1 exhaust manifold and X-Pipe? I'm interested to know how much improvement it makes, since it seems to be the only smog legal exhaust mod, besides shorties.
Thanks,
john

John,

Here is a Write-Up I did with video and a good amount of pictures too:

I know Eddie at Best Muffler in Lake Elsinore has done this set-up before.

Thanks for the write up Matt. I was hoping to hear from some owners with NA engines to see what kind of improvement it made. It would be great if was as close to LT headers as your supercharged engine was.

It will be very close to LT's - due to them being 3" all the way back or up to the 2 1/2" going over the axle (which will not restrict flow)

Awesome investment by far!

Hit me up whenever you need!

Thanks,Matt

I used Matt's guide and went to Best Muffler in Lake Elsinore, right down the street from where I live.
