I am gettin ready to purchase an exhaust system for the early part of the spring. I have a 2001 GMC Ext. Cab. Sierra with a 5.3 in it. I want an exhaust that is sounds really good, I have done some research and I like Corsa sounds and set up the best. I am also lookin at Flowmaster too, I am not sure what series of muffler to run with it. I am thinkin of running a dual rear set up. I want soemthing that also looks good and sounds tuff. Any suggestions for me.
Thanks!

 

I'll let you know about the magnaflow as soon as it gets here.

 

i'd vote for corsa....

 

I love the Corsa exaust on my Vette but Magnaflow on my Truck is damn nice as well.

 

Magnaflow

 

i JSUT PUT A MAGNAFLOW DUAL IN SINGLE OUT ON MY 6.0 DUMPED. the sound is good but it's not persoanlly loud enough for me, you can really only hear it during WOT. their is incab drone which doesn't bother me at all. I think I am going to take my cats of and put an x pipe on and see how it sounds. I didn't and wouldn't spend the money on a corsa(JMO) to pricey. ALso this was on a 14 in casing. anybody know how this would sound without the cats and an x pipe added?

 

i hope to get a corsa for my next Z71.

i like the looks and sound.

i like my borla too (looks, performance) but the sound is too mild.

 

MAGNAFLOW

 

I love my Corsa...nice and quiet inside, nice and loud outside.
