I have recently purchased an 02 Tahoe with the 5.3L in it. I am looking to increase the performance of this Tahoe and immediately thought of Borla. I had a cat back system on my 96 ram air T/A several years ago and it performed wonderfully. I was wondering if anyone out there has taken these steps with their Tahoe and what were the results. Good? Bad? Indifferent?

I have Borla exhausts on my 1992 Q45 and my 1983 Mustang and both are great. I put a Borla cat-back system on my 1999 2-door Tahoe with the 5.7L engine and I was not happy. The system looks great but at 1,500 - 2,200 RPM there was a really loud and annoying drone in the cabin. Unfortunately, the truck spends a lot of time in that RPM range and I had to get a different muffler. Borla did send me a diffuser to install after the muffler in the pipe but it did no good. The Tahoe sounded good at idle and when you got on it but that continuous drone was too much. I got the new muffler from the guys at a local Midas shop. It's their brand and sounds good. Not as much drone but it's still more than I really want. I'm going to take it to a guy in town that does a lot of custom exhaust and see if he can come up with a muffler that makes less noise but still gives me the extra power and throttle response I'm getting by removing the stock muffler. If you do go aftermarket, keep your stock muffler just in case. I wish I'd done that but it went in the scrap before I got to it.

I have a '02 Tahoe with a Gibson single exhaust and a Hypertech reprogrammer. My wife said she wants to go dual. Good combo, good sound and performance.
