m20 exhaust with m30

[FMH]

Will a m20 scorpion exhaust be ok with m30 conversion or will it be restrictive?

[rob0r]

I've used a not so good 325i system in the past and my latest conversion is a 325i scorpion, I'm anticipating no problems

Ideally you want twin 50mm pipes.

yer a scorpion would be quite restrictive in the M30

[FMH]

Dammmm. Going to miss the le mans tailpipes

I went from a standard 325i system then briefly a 325i scorpion then an E30 M3 scorpion with the twin 50mm piping.
When i went from standard to twin 50mm i seemed to of lost a little low down torque and not any real noticable gains up top.
Imo a 325i system will work fine.

its not stock/ish.

i'm sure Lee had the alpina b10, so that wasn't stock either

Yer 220bhp out the box is stuff all really.......

wtf is your problem?

[jimbom30cab]

If you read reggit's post he said not to worry about the exhaust pipes as the m30 makes stuff all power anyway

I sarcastically copied that post inferring that 220 bhp is hardly "stuff all"

220bhp for a simple and cheap conversion is pretty good in most people's books

So I dont have any problem thanks

[reggid]

220 is not alot for the pipes in question, certainly not worth a new system IMO. if it was a 260bhp alpina twin 2" or single 2.75" would be the go
