hey all,

bought a speed circuit wicked a while ago, long story short; I didn't get to install it till yesterday.

so I have it one, midpipe is oriented correctly, rear Y pipe is bolted and hung properly as well. fitment is preTTY much perfect.

I start it up, immediatly at the cat-to-midpipe flange, I hear a leak. the gasket is brand new and I torqed those bolts down, so I'm like wtf.

so today I decide to do some investigating. I jack her up, get under the car, and disassemble that flange. lone and behold, it's "bowed" in, from bolt hole to the other one such that there is a good 1/8" gap at the lower part where the two flanges meet.

not sure what to do here :/ i'm pretty bummed out. I mean, aside from that, the exhaust sounds absolutely amazing, and install went on without a hitch

any and all input is welcom

thanks

 

Find someone to mill it down flat or use a thicker gasket.

This is exactly right. Presuming the exhaust pieces are lining up correctly (which you should check) it sounds as if the one of the two flanges are not flat and don't mate well. Pull the parts off and take them to an exhaust shop. They should be able to grind it down in about 4 minutes. A thicker gasket would work too but I suspect might start leaking at some point. Better to do it right.

Though now that I look at AWDTerror's link for the gasket, I would do both. That's a nice find.

 

You can take it to a machine shop as well, or if you have a belt sander or time and a file you can do it yourself if you take is slow and use your head. The thicker gasket thing is a temp fix for a long term problem.
