Any of you guys had issues with your test pipe flanges warping?

For a long while I thought the stock gaskets reused were the problem of my exhaust leak at the test pipe.

Well I ordered brand new 2 bolt 3" gaskets and after installing I still get an exhaust leak. I inspected closer and it seems like the flanges are warped and the two flanges are not mating tightly.

I bought the Megan Racing resonated test pipe used and its been leaking since day one. With the car running I can see the condensated water spraying/dripping and when I put my hand there I can feel the exhaust leaking out.

I might just throw this away and buy a new one. I'm just curious if any one had the same issue with their Test pipes, whether its a Megan Racing or something else...

 

No I have the Tanabe test pipe and no issues it came with gaskets. If they are bent then it is never gonna seal 100% I would just get a new one and be done with it.

 

But I'm wondering why they would warp... I just ordered a brand new test pipe (should have gotten a new one in the first place), but I'm a little worried that from the heat cycle at this time if my downpipe and catback flange will warp as well connected to that test pipe.

This sucks, I wasted soo much time going under the car retightening the bolts and changing the gasket etc...

 

I really don't think the heat would be the problem maybe something happened to it by the person who sold it to you. Is it a heavy guage mine looks like you could run over it a not hurt it.

 

Well its pretty thick, not as thick as the OEM flanges. I think the material counts more than the the thickness.

What puzzles me is how they became this way? A mechanic friend guesses that it was probably bolted on incorrectly by the original owner and over time the heat cycles slowly warped it. He told me I can probably file it or get a machine shop to do it, but I rather just get a new one.

I guess this is a first then... Thanks for your replies.

 

Hmmm, Maybe go with a different company. You could have just gotten a defective one, did you try calling megan directly and informing them of your situation???

 

Well no point in calling Megan since I bought it used. If I got it new then for sure I would call them.

 

I would still call them how do they now you got it used or not, they can still offer customer service therefore provide some insight to your dilemma.

 

Well good luck with the new one and enjoy not having the leak.
