*** ASKING FOR HELP ***

Originally when I made this post I was in line for a 3 inch exhaust.
I was under the impression that's what I needed.
I read a post from a well known builder and his exact words was the "less back pressure the better".

After reading TMacs post a few times to understand it the best I can LOL.
I see that isn't the case .
Don't make fun of me i don't a degree in this field .

I did order the Corsa exhaust and It should be delivered Tuesday.
I don't mind selling it if needed, i just want to get the best performance out of my current build.

Any helpful advice would be greatly appreciated ..

This is my mods list .

You’ll be fine with 2.5”…no doubt about it.
I did 3”…only because I wanted a deeper tone and after 30+ years of building my own exhausts I had a pretty good idea what it would take to accomplish it.

Finding someone knowable to build an exhaust the way it should be done..
Isn't as easy as one may think, especially here in AZ.

No doubt on that statement. I would have gone the custom route if I had any decent exhaust shops around.

I think some in this thread have been breathing too much fiberglass. UNBROKEN and TMAC are obviously wrong. I'll probably need dual 5" exhaust for my stock ST. You know because of the boost and turbo spooling.
