........ let it go. I just installed a Corsa Touring unit yesterday. The cash for me is not a problem. I am going to have to drive it a few days before posting a full report in a new post. I can say how picky I am about in cab resonance from exhaust. I installed a Gibson and it resonated just a little and I dropped in the dirt and sold it for peanuts. I drove the Corsa a little yesterday and it is going to stay on if it remains the way it is for any length of time.

 

How much was the Corsa Touring and where did you get it? Does enyone else know where to find the best prices on Corsa's?

 

It's hard to beat http://www.tbyrnemotorsports.com when he runs a special, he is a sponsor here. ebay is good too if they have the model you want. Top dollar is going to be Corsa direct.

 

If you have any hookups at a GM dealer they can get them pretty cheap for you and you save on shipping.

 

I have an 01 ext cab 5.3, I just replaced the muffler on it. I was the same way, I didnt want the big flashy crome pipes. I think the factory pipes were 2.5 duals into 2 7/8 single. I just cut the old muffler of and used 2 short pieces of 3" to make up the difference in length. The muffler i went with was the dynamax ultraflow weld. (oval) The muffler is a straight through design. Sounds really good, not too loud not too quiet, really has a good deep tone too it. Has a little reasonance at about 1800 rpms. But nothing like the flows on my car. I didnt feel a big difference, But i could tell a diffence.

 

I have decided to go with just the muffler replacement, mainly because of limited funds. But now the question is, should I get a 3" single in, dual 2.5" out like the stock setup, or should I get a single 3" Borla Pro XS muffler? The guy at the muffler shop told me that the single in, dual outs flow better, is this true?
