Would it be possible to get a list of all the exhausts and their power gains?

Our axle back made 5-8 rwhp on all pulls... mid section added made an additional 1-2... weight / sound / look and some flow to aid in future mods is the investment

Same day back to back? So I might expect 6-10rwhp out of the Xtreme CB? That would be great news.

Yep, on Bakers car... No 2 cars are the same... some might make 1 or 2 more... 1 or 2 less.. I love and hate dynos, so many variables... all I know is we make sure Corsa outflows stock and sounds badass and lasts.

This is one of the runs we did in testing... not the best, not the worst, but an in between for you guys. Power gains is only part of the story and decision making when buying an exhaust X Y or Z. Nothing to hide from or fib about. If it made 0 or 20 the S550 exhaust and tone is now my favorite kit! Use to be the C7 Z06.

Blue= Stock
Red= Axle Back Sport
Green: Cat back xtreme

I think its been fairly well established at this point that the restrictive exhaust component on these cars (atleast n/a) is prior to cat-back section of the exhaust. Otherwise you would really see manufacturers/vendors jumping all over threads like this with dyno results.

Next week I will be installing my exhaust (ARH H-Pipe Catback) and dynoing after ... even with my supercharger, without changing headers, I will be surprised if I gain more than ~5-7whp at peak ... and even if I "gain" that much, I could easily chalk it up to different ambient conditions to when I dyno'd yesterday.

I just wanted clarity to the contradictions. I want the sound for sure and power if its feasible but I just cant justify $1000+ for a cat-back with the small gains. Like you said there are other mods to make the power for cheaper. I just wont be doing them right now as I intend to maintain my warranty for as long as possible. I'm more than likely going take the custom route for an exhaust as you can get the same sound for a fraction of the cost.
