I installed SLP 1 3/4 headers 2 years ago and one of the collector bolts between the header and y-pipe backed off. Now I have a leak even after re-tightening them. I need a new O-ring gasket.

I talked to my mechanic and he told me that before he replaced the 2.5" Collector Donut Gasket with ones he had there, that I should see whether a regular will do.... or are they a special component that I need to get from SLP to fit with their header.


Thanks in advance guys.

 

Mine leaked too so I just kept tightening it when the car was running (exhaust hot) & it went away

 

On mine, it only leaks when it's cold and everything is loose... it's been a cold winter here..... but after it warms up, it's ok.... but I get too many fumes in the car on start-up which is not very good for me or any of the passengers who begin to complain about the smell.

 

I was under the impression that no gasket was needed between the header flange and the y-pipe on these?
