According to diverce sources the recommendations is to go for an 2" exhaust when power exceed 100bhp. Any recommendations considering manifold as well on 2 box system with side exit? Preferably with the slide on fixations. Any good stainless steel options for the system?

Nah, what power exactly?

would not, did not go that big for 124.

 

but application and build will determine what size you need.

7-port, supercharged (~9-10psi), fuel injection (port injected), rev limit at 6500rom. Not sure how much power/torque I will get.
What I do not want is things going hotter than needed due to too much back pressure.

I did wonder why a 2" exhaust and now I know :)

 

I don`t think you can go wrong with a Maniflow system, you can talk to them and they can get you what you need.

If you can get hold of one, playmini used to make a 2" stainless system, but stopped producing them a few years ago. They often turn up second hand.

Bagsport do exhaust with your choice of size number of boxes etc
