I am awaiting my Stainless Works headers and cat back. With that, my roto fab CAI and a Pat G tune I will be set for a couple months. Magnaflow is always good too. https://www.youtube.com/watch?v=-0sM8jwHi40

Corsa Sport from the G8/GXP fits without any modifications, so does the SOLO axle backs.

I heard a lot of the G8 guys like the Solo J pipe stuff for a catback/axle back. As far as headers go I have ARH on order for my '14 SS sedan.

Alright, so it has been a few months since the exhaust went on and I am here to say that the Stainless Work system was not the way to go. The piping is thin gauged causing a weird howl @ 40 under light throttle, the mufflers have a head pounding drone @ 1,500 rpm with 1/4 throttle. There were two connection clamps missing from the kit upon arrival and I haven't heard a single response from their team after sending in a concern for their product on their website.

As for the Roto Fab CAI and Pat G tuning.....Money, both are wonderful. Now time to shop for a blower.

I have the Corsa and I am happy with it. There are two (2) o2 bungs that won't be used that must be plugged.

I have a Corsa on my G8, I like it, not overly loud when driving, gets loud when you put the hammer down. I'm running mine with Kooks LT's. The Solo exhaust options are popular with the G8 crowd also.
