Ok so I tried the XTC 2.5 inch downpipe with cat and took it off cause 2 weeks later cause I hated the Ricey sound. Now I hear that the Stock LSJ downpipe will rub on the coolant line or Swaybar so I don't want to bother with it. So is there any chance a company will make a 2.25 inch downpipe with Cat for us 2.2 Guys?
My local Exhaust Shop won't make a custom one for me due to Laws on Cat. Converter Tampering.
Any Hope?
Thanks for Your Imput

 

I have an lsj downpipe on my 2.2 and nothing rubs..

 

man i asked about this a few months back, the best response i got was to goto a local exhaust shop.... so good luck.

 

The Exhaust Shop told me that the section of pipe after the Converter that goes to the GMPP Catback can be replaced by a 2.25 inch Stainless with a Bung for the 02 sensor
Worth It?
Will I even feel a horsepower gain by taking some of the 1 7/8 pinch off the Downpipe
