I noticed that you have the MAC off road pipe. How does this connect to the y-pipe? I'm thinking about getting one because currently I have a 3" pipe welded to my y-pipe. I want to get a new y-pipe, send it and my headers out to be coated, and don't want to ruin the y-pipe by welding the 3" pipe upto it again! Does it have flanges on both ends so you can just bolt in place between the cat back and the y-pipe (no welding)?


Thanks,
Mike

Mike,
The MAC off-road pipe goes in just like a stock cat would.Its set up so that you can swap the cat right out and put the pipe in.The front of the pipe has the slip on fit and the back has the ball fit that goes into the exhaust pipe.It also has the air tube fitting too.(I caped mine off).
I had my pipe jet hoted with the rest of the TES system. looks good.
