From a previous thread here are some pics of the M2 exhaust setup.......

here are some pics of Jan's M2 exhaust setup

Sure Ray,

I had a round center section similar to the 02 Turbo section with a free flow Remus muffler.

We did a Dyno sesion at EDGE and found out that the car was putting 130 HP to the rear wheels. That seemed to be odd. We started to look around to see what could the problem be. That was when Erick and Gordon said that the car might have an exhaust restriction.

We went ahead and disconected the muffler at the downpipes and restested the car. To our surprise it went to 163 HP to rear wheels. Someone before said to me that the exhaust on the E30 M3 has two tubes all the way back and that I should do the same. I started to look around and found a used E30 M3 SuperSprint center section that I had modifed to fit the 02 tunnel.

I went back to EDGE to do another Dyno upon installing the center section. Well the results were great. We did three runs. The best of three was 169 HP to the rear wheels.

I will take pictures of the center section later tonight. I hope that this helps you guys with the M2 conversion.

Note: perhaps the problem was the "Y" pipe that connected the M3 downpipes to the center section.

Regards

Jan

Mojojoy.

thanks for the pics. Are there any Dyno comparisions between the exhausts. I know that Jan said he got a 30hp difference when he went to the SS set-up but not sure if it was going from a turbo exhaust. Hopefully, he'll chime in.

Ray, the skinny center section that's pictured above is the one Jan used during the Dyno and he was losing about 30/40 horser to the wheels and he went back and used the Supersprint one and gain the HP back.

all the pics are from Jan's M2 setup. He happened to have his car appart and told me to take pics of the exhaust for you.
