The thing im confused about with the SS headers, is that the power gains quoted on the SS website, was for the LHD M3s, which is completely different to the ones made for the RHD.

The problem with these power gains from bolt on mods and remap, is that people add each mod and believe thats what they will gain.
If cats give 10bhp, headers give 5bhp and a remap gives 20bhp (just random figures), then you will not gain 35bhp. The cats on their own would give 10bhp. But combined with other mods, its not as effective.

I think the 30bhp gain is possible with the full exhaust system, and remap, but not on a CSL IMO. The CSL has better cams, exhaust and airbox from the normal M3, to increase the extra power.

I could be wrong though. Here is a mates car, who has shrick cams, full system exhaust and remap.



So if a standard M3 has about 330bhp, then his power increased by +33bhp. 3 bhp increase just on shrick cams, if remap and full system exhaust gives +30bhp

Even though he has all those mods, i still kick his ass 1460kgs vs 1650kgs though

I hope you do gain 30bhp and have 380-385bhp, that would be awesome for an M3.

Sorry yes meant Sal and Thorney, now edited.

Well with the dyno graph you have there I can honestly say he is not getting the most out of them!

I have schrick 280/288 cams, SS stepped manifold, SS Full exhaust, remap with CSL airbox and if you want to go by rolling road dyno figures then mine is putting out somewhere in the region of 375/380hp depending on the day, this was done on 2 different and independent dynos. However further dyno time is needed, now that I have realised that my HG is gone and my fuel pump was not producing adequate pressure.


I agree with Xcalibar though you cannot just bolt bits on add up the figures and expect to see those power figures it does not work like that. Although some companies will tell you it does!
