CrossOver Pipe Flange Question
 
I am replacing my Cat with a M&K pre muffler on my 1980SC
The Flange on my Cat is rusted out and i am not sure if the crossover flange will hold up.
Is the flange on the crossover pipe separate or an integral part of the pipe ?
I am wondering if I need to buy a crossover pipe.http://forums.pelicanparts.com/uploa...1365639528.jpg

I just did this same project and my flanges looked as bad as yours

the flange for crossover pipe is part of the pipe it does not come off

I had to cut all bolts off with dremel tool and hammer out remaining studs then I used the dremel to clean up flange face to make a good seal

I doubt you would have to buy new crossover

From the looks of it you should be ok. I had the same issues with my 84 Carrera and I dremeled off the rusted bolts and a couple taps with the hammer got them out. Then I had the whole exhaust bead blasted and I painted it with a little high temp silver paint. New gaskets all around and no worries!

Well that would be nice if I did not need a new crossover pipe as they are $235 new.
At least some of the bolts and nuts have pretty much disintegrated.
I am not looking forward to cutting out the remaining bolts.

There does not seem to be a whole lot of room to get a Dremel up in there even with the flex extension.

Don't be afraid to put a little muffler seal goop on it from the local parts store when re-assembling. I played hell with sealing mine with the copper gaskets that came from Fabspeed when I installed their pre-muffler. Believe I just put new OEM gaskets on with a little dope. No problems since that I can tell.

I did not use the flex extension

I have a lift so up went the car and off went the wheel and there is plenty of room

Just take your time and have fun it's not that bad of a job

What kind of bolts did you use ?
1) stainless
2) copper nuts
3) steel w/anti seize

Ok, Thanks for the help I will give it hell.

I am not familiar with this product.
Do you apply it right over the gasket on both sides ?

What kind of hardware did you use ?
Steel, stainless, copper nuts, anti sieze ?

Thanks for the input.

Exhaust Leak & Gurgling on deceleration.
 
Maybe this exhaust leak explains the gurgling & popping when I let up on the
gas.
