For all with exhaust leaks....

[AbsurdNY]

I just fixed my header to downpipe leak today and I wanted to tell everyone that has a exhaust leak FIX IT! As soon as I fixed mine, no lie I felt a difference in performance and the car felt like it drove smoother for some reason.

Yea, my header is leakin' from the 4th port, where it's connected to the head. It's blowing black smoke onto my valve cover and stuff. Plus, I hit a bump and bottom'd out the front of the car, and put 2 dents in the downpipe. I'ma just buy a new one. I'm sure those 2 dents in the downpipe are hurtin' me, since my o2 sensor is after the flex. But yea man, exhaust leaks do some damage. Plus, the random raspy sound they make.

Well some people might put fixing it off for a while because they think it don't affect anything but the sound. The header to downpipe was very easy to fix. I just took off the downpipe, scraped the old gasket off, put a bunch off copper sealant on the downpipe flange and the header flang, waited about 15-20 mins, then put it back together and let it dry overnight. When I but the downpipe back on, I took that metal bracket off the car that holds the downpipe to the frame right before the flex pipe. On my car, this was holding the downpipe on a angle so the flanges were not sitting flush and thats what caused the leak and blow out. Here are some pics:

Shit ebay gasket lasted about 2 weeks.


My fix




Problem solved and was free because I had some copper sealant laying around

If i put the bracket on, right now i will have problems with the flange because it will pull the downpipe down more then it should be. I might fab up a plate and drill some holes and slap that on in a couple days.

Is it on a straight section of pipe? If it is, a quick fix you can do to temporary stop the leak is cut both ends off a soda can and then slit from top to bottom on one side. slide it over the leak and use 2 hose clamps to tighten it down. It won't last forever but it will help until you get it fixed the right way

Depending on where the exhaust leak you will lose power. Its just noisy the only thing I see. I had a leak in my piping before the muffler.
