I am just curious if anyone has a Corsa exhaust system on their 1999 or newer Silverado? If so, how do you like it? Do you have interior resonance? Did you lose any low end? etc...
I installed a Gibson swept side single exhaust on mine, and I was very disappointed in the sound. It was too quiet, and I lost bottom end. I then installed a Cherry Bomb glass pack in place of the muffler, and I got a good sound, but the interior resonance was just too much. So, I took it off and put the stock back on.
I still want to put exhaust on my truck, but I dont want that interior resonance. Someone told me to put a straight pipe on it. I would think that would be REALLY loud! The Gibson system is 3" from the cat all the way back.
What size pipe is the Corsa single exhaust?
I know I am asking alot of questions, but I really want exhaust on my truck, and I am just looking for some opinions.

Thanks!
