I have the alphawerks header and Megan S pipe, Greddy EVO2 axleback and as of now my OEM mid pipe is back on (Long story don't ask). Sounds nice but here's the problem:

I have a leak at the S pipe and Midpipe gasket. Now I tightened down, and actually I went too tight and cross threaded it

So i tapped it and put new threads, this time put a nut on the otherside and had at it. Thinking it would be better I started the car, climbed under it and to no avail. I still have the leak. I have tried loosening the header bolts to allow some wiggle room to get a slightly better seal at the S and Mid pipe but it still leaks. I'm about to take it to a local shop and just have them weld it because I'm tired of dealing with it, but I want that to be my last resort

Sooo....before I go and do that, I know a few others on here have had leaks at the same location so i was hoping to get some ideas.

 

bump...

 

make sure u have all 3 gaskets on the s-pipe...mine was a bit^h to install


other then that, good luck

 

thats the problem... i do have all three gaskets on and its still leaking

 

hum.....unless you have a broken weld at one of the flanges.....you might have to have it welded, just b/c it may be the weld in the pipe....

sorry i couldn't help ya

 

its cool... at work bump

 

do you hear air when you accelerate? i have the zpi s-pipe and i do have a leak right now, but i've grown past the fact that there is one. since heat expands metal, the leak is gone after the car is fully warmed up.. when i start up the car, i dont hear any sign of "air". there's a gap in between the s-pipe and the header because of the gasket, if only zpi made their s-pipe opening a little bigger to sit flush. bleh.

 

thats whats weird my header and s pipe connection have no leakes, however at the mid and s there is, i hear air when i accelerate but only in tunnelsor under bridges is it audible. When i first start the car is when I can hear a "whoosh" of air come out... bleh i'm just gonna go get it welded i think

 

exhaust cement?

 

Go to autozone and buy a tube of RTV compound

 

uhhh... to be honest I never heard of it, i take it it works just like it sounds, how easy is removal??

 

when you want to remove it, its easy. Trust me, it should solve your leaky seal issue, go talk to the guys at autozone they should agree.

 

yeah i was thinking about getting that.. whats the difference between the "RTV compound" and Permatex's Ultra Copper Gasket?

 

I second the RTV compound..stuff helped me with my exhaust leaks that I had on my megan cat-back.

 

Sorry dont have any experiance with permatex. RTV has never failed me though

 

bump

 

 

i think mine is starting to sound like this....its like really raspy if you rev it when the car exhaust is cold(no header, just s-pipe, and megan with 2! resonators) but the rasp goes away as you drive around....

wondering if megan didnt align the pipe correctly...

 

make sure all the gaskets are installed correctly
