Hi guys, this is kinda wierd. I've been looking around at catalytic converters for my car. I saw the complete assembly for sale but there is some confusion. The manifold for my engine (darn 10 valve!) has the 4 bolt hookup for the cat. But the right cat. for my engine doesn't have the 4 bolt assembly! it has i think a 2 bolt hookup with the gasket...WTF!!!! am i going mad!!

You could always take the car to a muffler shop and have themweld a nice high flow cat.
Maybe you could get the whole exhaust system done (3in downpipe to a2.5in cat-back).

 

This is the one you need correct?

 

Possibly get an adapter fabricated up?

 

Hi guys...

TIPSP..the thing is that my engine is N/A not turbo so i think it needs some backpressure?

TECH..hey Dude what's doin? ya this is the cat in question...it's been hard to diagnose, i need someone else to keep the revs up while i look underneith..

PSABOIc..ya depending what peice needs to be changed..

I'll try to get it checked out this week...

Yes, NAs need some backpressure.
My dad just put bullet/race cats on his NA 540i with no problems, I think it is the muffler choice that is crucial. Though I am not 100% sure.
Not sure if you looked here yet? Here are the two, but they have huge price differences.
This cat has the four bolt hook up:
