Engine size and what exhaust you have would be helpful?

If im correct, you have a mtec2 sport - usually this would have a 2 piece system

Scorpions usually are 3 piece systems - so you may need to get an exhaust place to weld it on or create pipes - or get the centre and front pipes to do it urself.

otherwise its an easy job probably 1 hour or so

mines a scorpions back box mate its got 2 pipes same as the exhaust on it and yes its a 325 tec 2 would u think its simple unbolt and bolt on ?? if so mostly would u think i would be able to do it on the driveway or should i just pay a mech to do the work as i wanted to do everything on my e30

The key thing is if its a 2 or 3 piece exhaust.

You will need to get under the car to know for sure as there is no hard and fast rule as to what cars have a 2 or 3 piece system at this age as it could have already had attention.

If you have a 2 piece fitted and the scorpion box is for a two piece system it should just bolt together. But if one is a 2 piece and the other a 3 piece you will need the pipes extended which will take some work from an exhaust place.

o ok when u meen 2 3 piece my back box on the scorpion that connects to the rest of the exhaust has 2 pipes same as the back box on it based on that would that mean its a 2 piece n would u say doing it myself would be easy if not il just drive it down worst case if ifuck it up

No, the exhaust on a 325i can come in two or 3 sections. A 2 piece exhaust front section is connected to the manifold at the front and the rear section connects to the front section.

A 3 piece system has a downpipe from the manifold, a mid section and a rear section.

The back box for a 2 piece looks like this:

And a 3 piece has much shorter pipes where it would connect to the middle section.

just out of interest, does a 2/3 piece exhaust include the manifold or not?

i.e. is it manifold + 2/3 other sections? if that makes sense

[Rtaylor2208]

A 2 piece does not include the manifold. Basically the front section connects to the manifold and runs to the middle of the car, the back piece is the backbox.

I believe the 3 piece is downpipe from the manifold, center and rear sections.

yep -
manifold + front section + rear section = 2 piece

manifold + downpipes + centre section + rear section (shorter) + 3 piece)
