I picked up an 06 GMPP catalog at the PRI show and in the back it has listings for cat-back exhaust systems, are these made by corsa? The exhaust tips described in the catalog don't sound like the goofy twin tips that corsa uses. They had cutaways of the mufflers in the gm booth but I didn't get a chance to ask anyone about them. Looks like they offer a "touring" muffler and a louder "performance" muffler. I'd really like to #$%^can my stock SS system but I don't want anything that is much louder(go ahead and tell me it's not possible). My cammed 6.0 with the aftermarket cats and 3" hd downpipes is loud enough. Thanks.

 

GM just switched from Corsa to Borla as their supplier.
There are also GM specific tips available through GMPP which you won't find elsewhere.

 

Thanks for the info. Do you know where I can find specs on this system, pipe size, muffler size and are the optional tips required?

 

They have them listed on GMGoodwrench.com.
