Thinking about getting one of these manifold. Just wondering if they are worth the money. I have an '89 325i Sport with BBTB, Scorpion back box and Superchip. What kind of power gains would i expect to see and what is the noise like? Also is there much involved in fitting? Cheers.

I had a big v8 ford in Oz once.
It had two four branch stainless.
It breathed alot better and ran cooler.
You could really hear the engine more but not louder.
I too am looking at getting a 6 branch for my 325i Touring.
Power gains are 15 bhp. Thats very good for a bolt on.
Do you have a two or three piece exhaust?
I have a two piece and am still wondering if I can connect the manifold downpipes straight to it???

Obviosly the center section will need to be cut but will the downpipe fit snugly?
