new H-Pipe install question

[99prmustang]

hey6 all i jsut got done installing my new mac h-pipe on my gt.
it sounds like there is a leak on the passenger side header to pipe connection but i see not smoke or feel no air. could this just be the sound of the pipe breaking itslef in? do they even do that? thanks

once again those of you on stangnet have failed me again. is it so hard to answer a simple question? i used to be a thirdgen firebird owner, and the people on thirdgen.org where amazing on that message board, always had a helpful answer to all questions, i am on my second stang now, the 5.0 guys where always very helpful when i had my 89 gt. but i have been dissapointed more than once on the 4.6L board here on stangnet. thanks alot

Start your car up and go to where you think the leak is. Take a piece of paper (notebook paper works best). Hold it close to all points around where the header and pipe meet, if there is a leak you will see the paper move where the leak is. Hope this helps good luck.

did you replace the studs coming out of the manifold , if you didnt thats your problem , replace them that way you can get the flange good and tight , problem solved

Before you start slamming all the good folks in the 4.6 forum, look at your original post. It took me 2 or 3 times to figure out what it said. Spend a little more time composing your message and you'll get more answers that way.
When installing a new H-pipe, make sure you tighten the passenger side(solid mount) first, then go to the driver's side. I had absolutely no problem with my MRT H-pipe. You get what you pay for!

Did you put the gasket that's on the passenger side back on?

sorry for slamming you guys, i jsut need an answer asap. i didint replace the studs, so ill do that when it stops god damn snowing up here and yes i put the mac gasket in that came with the pipe. one other question is did the factory h-pipe come with a factory gasket at the pass. side header?

 

[2002BLGT]

yes it did , thin metal one , with raised packing material that fit in a groove on the factory manifold / hpipe connection. should have fell out when you took down the old one or its stuck to the hpipe or manifold .
if the mac came with a metal type gasket sometimes they will leak when cold very very very slightly but seal up once they get hot , if it was a thick paper type it should seal good but will blow out under alot of pressure . change the studs and take the factory gasket to a parts store and match up if yours is blown out already since you probably didnt get it tight enough because of the factory studs , might have to do some trimming to get one to fit good , just make sure it seals all around and bolt holes line up , get a metal one , it will last longer and hold more pressure from blowing out

Spraying soapy water from a spray bottle works too. you'll see bubbles
whee

have you fixed your leak yet ??? smoke is probably just the added condensation in the pipe from sitting overnight . its alot more noticeable with offroad pipes
