Curious to know if anyone has run a set of longtubes, off-road y, and single 3" or 3.5" no muffs out the back. Thinking of trying but will still probably run high flow cats. Looking for some different ideas for performance but want it to look stock.

 

If you do the LT's it wont look to stock. There are a lot of guys running that set up on their trucks and works great, i should be getting my mid pipe made in a few weeks for my long tubes. 2.5 collectors and y pipe to corsa cat back. Do a search for AEM headers, i remember seeing some good pics of a guy having stock cats and modified stock y-pipe with the LT's.

 

You mean ASM? They are made by Arizona Speed and Marine.
