So I just installed a test pipe to accompany my greddy to-c catback, and ever since i have a persistent exhaust leak that I can't seem to get to go away. I have a brand new grimspeed gasket in place and it doesnt seem to be working. I have tightened both flanges as much as possible and still nothing! Where do I go from here? Gasket sealer?

 

Gasket sealer. I need to pick up some myself.

 

does gasket sealer make it difficult to remove the exhaust later on down the road?

 

And is doubling up on gaskets at a single connection a bad idea?

 

Would like to know as well, because I am replacing the gasket on mine tomorrow..should I go with gasket sealer just in case?

 

I always put grey sealer after an exh swap.

 

Do you know it's at the test pipe? Once I put my cat in and I got a leak at the top of the DP. I had to adjust it and it was fine.

Also, isn't the grimspeed gasket pretty thick? Any pics of the leak?

 

I'm positive it's at the test pipe, cuz I can feel it by reaching my hand under and feeling it. It's on the top part of the connection, the bottom half seals. And yeah they are pretty thick gaskets, got em' from rallysportdirect here in Salt Lake, brand new.

 

I'm starting to think I'm just going to use some gasket sealer tomorrow. Did some research and everyone says it works great, as long as you get stuff that is capable of the heat.
