this is the headers on the car 3 size stepped equal lenght tubes into merged 3.5 oval, part of the reason for the flat torque n power past 8000rpm, the free up intake should really wake this thing up

wow those look amazing - are they E30 specific? custom built?
I had a set of the ebay headers, only $65. man, I got what I paid for. I sold them to somebody else who was going to cut them up and make a jig to build a "real" set.Comment

fronts r 1series 6 piston calipers with e46m3 csl rotors with my adapter kit, rear r 1series 2 piston calipers with e46m3 csl rotors mounted to m coupe control arms, it clears 17" wheels with no problem, stops like a airplane landing on a aircraft carriersigpicComment

the answer is yes, about 5yrs ago b4 s54 became a popular swap Don (kromerkraft) n i designed the headers, alot of thought went into it as far as tube length, different primary sizes, dia of merge collectors etc, based on my dyno results the headers produce a very flat tq band(266 tq max) n was still making power (322whp max) past 8000rpm with the motor running very rich (stock intake, stock engine, street tune, custom headers) i'm going to do some more dyno runs with different intakes n tunes, i won't b selling a pretty headers, i'll b selling a headers with proven results compared to what else is out there, even the a/c compressor fits with no problem, i'm in talks with a well known header company about building these, stainless steel only, more to comeLast edited by bimmertc; 12-28-2012, 07:23 PM.sigpicComment

Looks awesome.
More dyno charts? Is this MSS54 ecu or did I miss what you were running?
Great looking swap, nice and clean! Keep up the good work...'88 M3.2 S54 Lachssilber/Black
