Corsa Exhaust Question

Thinking of removing Corsa exhaust and going back to stock 2002 tahoe system because 6.0 Lq4 swap is alot louder than 5.3 was. Sounds like I,m at the track when on it, the new power is great. I,m attracting alot of attention and i,m affraid of police action may be coming soon. Is the factory exhaust system going to be as good as corsa cat back system? Is there any power loss from running factory system. Will the stock system be good with a future comp 224 114lsa cam kit also? some one said factory exhaust flowed very well? but just quiet!

My Corsa is quiet when just cruising around. It is only loud when I romp on it. Keep it on, just keep your foot out of it.

I highly doubt the factory is better in any way over the Corsa. :twocents:

The factory system is probably the most restricting there is.

Jamest

My Corsa got very loud/raspy with addition of headers and free flow cats. I have the dual rear outlet sport system. I put in 2 magnflow bullet mufflers in the tailpipes. Quitened it down and sounds very nice.

Here is a link to what I used.

You can see them in this link I posted on my new wheels, last picture right before the tips.

Other guys have put it inline before the muffler with good reported results. They make a 2.5" also I think.

dude with the LQ4 id recommend a 3 inch exhaust all the way out for better flow :thumb:

I am using a 6.0L touring system, so that might be the difference maker. I bet you could swap someone for their touring, everyone seems to want a sport system. But not me.

I would like to swap or buy a touring system. The Part number I need is 14221 (Touring) 6.0 4x4 Yukon, Denali or Escalade. The system I have is for a 4x4 tahoe 5.3 part number 14232 (sport)

Try posting this on PT.net as well.

I have the Corsa too and love it, my brother got his used from craigslist but I wanted a valid warranty so I got it here. Corsa Exhaust 14232, or you can try one of the sponsors here on the forum, they are allways having sales/specials. Either way its a great exhaust system, sounds great, and very easy to install.

I was the same exact way man. I had the sport on my truck with my 224/224 cam, no cats, and longtubes it sounded horrible.

I ended up swapping to a full 3" exhaust with the stock muffler at the end, BUT I put a DMH 3" cutout before the muffler so I have hardly any restriction when it is open.

EDIT-I have a touring muffler I might sell for the right price. It's brand new and will swap right in. I'd like to get $250 shipped for just the muffler

i have the corsa sport muffler on mine, i absolutely love it quiet while cruising and deafening at 3k rpms or more its AWESOME. the police LOVE it ahhaa.
