I have got the standard back box on my P1 at the moment and I would like to replace it sometime.

I was thinking of just a P1 WR back box. Would I notice any power gains from this?
I don't want to go de - cat because I want to pass the MOT.

What are you guys 'n' girls running out there, and thats worth buying?

 

I switched from the normal exhaust to a HKS Hyper 3" exhaust on my P1. Didn't notice any power gains cause it's an already powerful car.

Difference is in the noise

Do you want noise? If so the HKS Hyper is well loud and releases the flat 4 grumble nicely

 

i used to have a full scoobysport system on mine, you could replace the mid section and back box and still pass the mot
mark

 

For example, how would a scoobysport back box and a tsl center section sound or instead of a scoobysport BB how about the P1 BB.

Which one would give you the best power gains?
