I've got a 1999 classic with a Sports back box and i'm after a new exhaust.

On the back page of True Grip magazine i have seen the Revolution advert for their exhaust, they sell one that can give 39 extra bhp if you buy the system and downpipe for around £480.

Is this good value?
Will it give the power it claims?
Does any one have one?
Will my car still pass the MOT?

Sorry for so many questions

 

Can only tell you that if this is a decat system (which seems almost certain at this price) then you're most unlikely to pass your MOT.

There is a Group Buy on H&S exhausts at the moment, BTW. Check out the Group buy section.

Best,

NS04

 

I don't know much about revolution, but for a turbo back exhaust that seems a reasonable price, Japanese brand exhausts such as blitz and HKS etc. are around 500pounds for a catback system.
Probably not alone! In conjuction with an ECU/ Remap then yes.
If it's a turbo back decat system your car is highly unlikely to pass. Options are change it over for MOT time or find a performance friendly test centre

 

Go for Hayward & Scott, you will not regret it.

A good selection of back boxes to suit all needs aswell
