Hey guys, what are you using for a plug on the back of the plenum on your Whipple gen5 3.0. It looks like it should be a plug with an o ring. First picture is my gen5. Second picture is my old gen4 with a plug that it came with from Whipple.

Looking for a ARH cat-less x pipe. Either a full 3” or a 3” that necks down to 2.5” will work. Thanks

First time ARH owner here, I know there’s a decent amount of you guys running the ARH longtubes and I’m curious if anyone else has ran into this problem. My 3” x pipe does not have the male socket end that is needed to bolt it to a catback. I see pictures online and it looks like some are like...

Selling my M55 catback, fits all IRS Cobras. The driver side muffler has a dent in the front of the muffler and both pipes have scrapes along the bottoms. This is the lowest hanging catback I’ve ever had which is partly why I’m going back to my Borla catback. Besides how low it hangs it fits...
