Question for guys running 3" catback exhaust
 

Hey guys, I still have a small exhaust leak from where my front pipe meets the mid-pipe/catback. My catback is a 3" from Perrin and my front pipe is a 2.5" from Invidia. I'm getting a slight exhaust leak where those two meet and I don't think I can use the stock donut gasket because its meant for a 2.5" stock exhaust. Has anyone had leaks in that area?...if so what type of gasket would you recommend? A guy from Brakes Plus said he recommended a thick 2.5 flange gasket (5-8mm)....does this sound reasonable? Any tips would help, thanks guys!

Maybe this, maybe?

I'm sure you could find one cheaper if you googled for more than 3 seconds.

Nice, I didn't even know they made a conversion piece!

GrimmSpeed makes a cheaper one I think. I haven't bought mine yet tho lol.

Or you run 3" all the way and call it a day!

Exactly!

Use permatex copper gasket maker. Works like a charm

This!! Been using that since day one that's why I havent bought the part from GrimmSpeed.

I bought the grimmspeed 2.5" to 3" adapter and it fixed this issue on mine perfectly. Im actually switching to a full 3" header back so I would give you mine cheap if youre interested.

Hey I never saw this. Do you still have the 2.5" to 3" adapter?

sorry I just got rid of it last week :(
