I just rec'd a custom downpipe for my turbo kit. It has a 3 bolt 3" flange welded on the end. I also have a thermal 3" catback exhaust with the same type of flange already welded on.

Just ordered a 3" universal magnaflow cat (no flanges)

I want this to be fully bolt up with as little fabrication work as possible

I saw this product in the summit catalog

My idea is to measure the length i need, then have these welded on each end of the cat, leaving the triangle flange 'floating' so it can bolt up easily. I would use the gaskets also.

Will this work? Will this last? Will it leak? Is this a good idea or a bad one i had while smoking and thumbing thru the summit catalog?

thanks...

 

Just use a gasket. These are the type of flanges that I have used on every domestic car I have owned.

 

bump for some opinions

 

no reason you can't have flanges welded on each end of the cat to mate up to the downpipe and exhaust.
the idea you have should work i guess,the only concern would be leakage.
also,make sure there's a flexpipe somewhere in there between the downpipe and cat.

Ive used those before, and they actually hold up nicely. Seals perfect, but make sure you put that gasket in between.

 

I cant weld. so to weld the flanges on the cat and getting it exact requires me driving my car to a shop, getting it on a lift etc. All cost money and i have no one reputable to do it.

Theres a flex sectioi welded into the downpipe.

so the consensus is that i can do this? Just make sure i use gaskets?

 

Wells,

Have you notice both ends of the Magnaflow Cat is a little flared?

Meaning, you can slip in 3inch pipings into it. Will save you time and money. -=P If you cant weld, then use exhaust clamps in the mean time.
