i am thinking of removeing the front cat
which is best a twin or single down pipe and why ?

 

look at scoobysports web site and see the size of the group A downpipe and you will find less restriction a guy at work has put one on and the turbo spins up earlier.the twin pipe thou ok if you look at power engerneering or tsl web site you will see what I mean

 

Paul go for the single matey boy. I heard that you may get problems with a twin but that said, nothing will sort your piece of junk out!!!!!

 

I went for the twin dump Scoobymania system no problems only massive grins

As for comparing a WRC car to the std road going version would you compare a BMW-Williams to the 316 compact?
(~ok a bit over the top on the comparison~)

 

 

c&k in manchester said a bpm twin is the best also the most costly are they worth the extra £££?

 

There was a massive opst recently on the merits of the twim dump, If you look back in this forum over the last 10 to 15 days it should be there, entitled BPM downpipe.

 

okay, it is back now anyway by conicidence.
