OK, sorry. I'll keep my mouth shut from now on.

Please don't... not one person on here doing an M6x swap that doesn't look up to you for leading real world experience with this engine on an E30

The M20 manifolds are just logs, but S52 manifolds are decent for shorties.

Only 1 of the M60's is try-y ;) which is something I found interesting.

Only the late M62 and X5 are this configuration. On the early M62 the manifolds are two pieces on each side, meeting in a y-pipe on each side.

[smalcol]

I don't think an x-pipe or anything after the manifolds will make much of a performance difference. Most of us already have nearly straight-through designs, different mufflers will tune the sound. I have a magnaflow, as seems to be the most common, a flow master will probably give you a deeper sound. If you want to go in a different direction use the M60 or early M62 manifolds. It's way more work, that's why everyone uses the late M62 or X5 manifolds.

Well I'm Keeping my header setup as is. I'm also thinking of keeping it a true dual to begin with. Running a set of SLP Cats #M310193500 for ( 2 ) reasons, -1. Being Hi-flow cats are perfect Resonators, -B. The one common element that all the bad ass euro v8 sounds that i have found run hi-flow cats, And -5. I'm hoping it will give it a tad bit more of a stock look if for some reason my car is inspected by the fuzz...

So after all that I will be running 2.5" all the way back to ( 2 ) Magnaflow 18146 4" x 26" and a ghay'ish stock looking tips to fool the grayhair's at the car shows...

and after all that not so cool sounding typed letter crap it will still support my build when i mount my SuperCharger under the hood of this beast.;D

Man I love where your going with this exhaust...cant wait to be at that stage but realistically wont be until next spring.. but meanwhile :popcorn:

Ok so I didn't get the SLP's like i wanted and now that option is at a higher price

But now i have another question before buying a different set.
If I'm going to run a cat as close to the headers as I can (that is my plan)
Should I get cats with with o2 sensor bungs in them or should I run the o2's before or after the cats?

I'm looking at a cat that i have the option of an o2 in the center..

[smalcol]

You want the O2 before the cat, anything else is going to give you false readings. The only reason to have one after is for measuring the efficiency of the cat.

[MonkeyMadness]

Ok kool. The one I'm looking at now is a high flow with the o2 bung before the cat element but still in the body of the cat.

[LJ851]

Why don't you just weld a bung in the pipe? You would have a lot more freedom in cat selection.
