The dual style catback for the 6L all it has that is different is a y piece that combines the two pipes from the manifolds to one then goes in a normal silverado system. I thoroughly researched this. Same muffler for both systems. This a great deal slowvan79 you should jump on it if you can. You wont find a better deal for a long time.

 

I purchased the Touring version from Tbyrne for my Silverado SS and I think it killed the better part of $1500CDN by the time I got it to my door in Ontario.

P.S. I'm really looking forward to becoming one of the few Radix'ed Canucks next year!

 

the pro sport is the gmc sierra special edition model name. it comes with corsa/20's and a tonneau cover, maybe something else. is special for new england. i've also heard of a special edition texas gmc but cant remember their name for it.

 

I was reading my last post and I said something wrong. The muffler for the 4.8/5.3 is different than the one for 6L but the same as far as the external dimensions and the way the exhaust enters and exits it. The inside is different for their RSC technology so it doesnt drone and all that good stuff.

 

I believe that the current GP would save me around $450 CDN off of what the stealership wanted.

Only problem is that it can turn you into a horsepower junkie!

Yup Corsa Sports all the wayyyyy! These things rock! Super loud when you are on it and dead silent cruising (even with LT's). Not to mention that not many people on the road has it.
