First Post - Warped Downpipe
Hello All -
I am new to this forum - I have a '92 1.6L with one of the early FM turbo kits with the IHI turbo and Link (MKII) engine management.
Recently, I had to have a crack in my downpipe welded and in doing so ended up with a slightly warped downpipe. It's not a major problem, but not the distortion in the pipe is just enough to cause the exhaust to contact the power plant frame just behind the cat.
Any suggestions for "adjusting" the shape/angle of the downpipe? I thought about heating it up and trying to bend it, but have concerns that may lead to more cracking.
Thanks!

The problem with bending it off the car is you don't know what kind of change you're making without reinstalling it. And you're right - using mounting points to leverage a bend does stress them. Whether or not your concern is justified is another question - but denting the pipe avoids those issues at the price of aesthetics and flow.

The worst part of the problem is that the pipe is touching the PPF at the flange behind the cat and rear section of the pipe. Unfortunately, I really can't deform it there to keep it from touching. It doesn't sound like there are any good fixes without taking the pipe off to adjust.
Oh well....as I told my CFO (aka my wife), I guess its time to pull the IHI turbo off the car and install a new Garrett turbo and downpipe. Sounds like the only REAL solution to the problem.

Yes - that would probably help, but I suspect that I'd have to take off more of the flange than I'd really want to.
I'm thinking now of trying to use pair of wedges on either side of the pipe to brace the upper section while prying on the lower section of the downpipe. I'm hoping that the wedges will limit the torque applied to the turbo flange and housing.
