325i exhausts

[mattqf77]

Are Standard E30 M20 320i and 325i twin pipe exhausts the same? Think front section on my 325i is from a 320i and bit worried about if there is enough flow etc

Yes...

BUT,there's always a but with this type of question!

Manifolds can have three or four mounting studs to the down pipe,
Systems can have two or three sections.

The systems are interchangeable complete,you cannot mix 'n match.

they aren't the 320 uses much smaller bore pipe akin to a twin pea shooter to the 325i. As said you can only swap entire systems over.

A 320 system will restrict the performance on a 325

If that's the case thinking maybe better to change whole lot for performance exhaust system. Are scorpion any good?

[tonybtonyb]

Yes they are very good I've had mine for just over 10 years now,still going strong they do come with life time guarantee and are cheaper than buying a standard system from a main dealer

[mattqf77]

Is scorpion loud compared with standard exhaust?

[tonybtonyb]

They are when you put your foot down.

What would be better option between Fritz system and Scorpion???
