I just put a Corsa sport exhaust set-up on my 09 Silverado (5.3) and absolutley love the sound of it, but I was wondering if anyone had any tips to make the exhaust a bit louder without changing the sound too much, esp. at idle (i.e. high flow cats vs. headers). Thanks for the help.

 

cut offs. run the exhaust to dump down at about the rear axle. or like on my truck i have it cut off and dumped about 5 inches from the muffler. its loud and still sounds good.

 

I'm not going to dump it, I really like the look of the tips and don't want too much interior noise. I was more iterested in info about high-flow cats or LT headers.
