I have a new wsp full 2.5" exhaust. When I installed it, I overtightened the flange from the y-pipe to the cat and the flange from the cat to the b-pipe. Now it leaks. The flanges are only two bolt flanges and if you overtighten them they will bend like this =()= (the equal signs represent the piping and the paratheses represent the flanges). They aren't actually bent very much at all but, it is leaking some. Any ideas on how to fix it easily? Maybe something I can put over it like putty or if I took it to an exhaust shop, how would they fix it without welding it together?

 

that doesnt make sense. Its supposed to have gaskets between them and they should be flat when pushed up against each other anyway. If they are truly flat (like they should be) then they cant bend like you are talking about.

If you didnt get gaskets with the kit call them back and ask them to send them. If for some reason they did bend then that means that they were made incorrectly.

if they are bent slightly then you might try sandwitching two gaskets per connection to see if that helps.

 

muffler cement

 

They do have gaskets between them. They aren't flat when they are pushed together because there is a slight lip at the end of the tubing that holds the flanges on. If that lip wasn't there the flanges wouldn't hold the two ends together and the flanges would just fall off. I wish that the flanges were welded on like they should be but they just aren't ffor some stupid reason.
I've decided that I'm probably going to sandwitch two aluminum (not crappy papper gaskets) between each connection.

How well does muffler cement work?

 

that depends on how big a hole, and whether it flexes at that point

 

You have to unbend the flanges. Cattman Y flanges are thin and bend easy. You will probably never get a good seal without getting the flanges straight. DAMHIK this. Normal 2 bolt/3 bolt exhaust connections are iffy at best when they are straight. Trying to seal bend flanges is an excercise in futility.

 

Do not use cement. Lasts 3months as the system lives, cement does not.

Bend them back or make a suitable o-seal.
