has an one had one and is it ok??? mines a bug eye 52 reg ppp

just guna get it dectaed and mapped later on

 

If you have the ppp you have a prodrive sportscat,so I wouldnt bother with that, I would get your up-pipe decated instead!

i dnt no if it has...it had it added at 33k mines got 63k nw

 

do you have an invoice for the fitting? was it done by subaru?

all i hve is a certificate mate, i ran prodrive them selves 2 days ago sed it had prodrive added....

 

in that case you most certanly should have the ppp downpipe!

I would personaly leave it in there

regards
Rob

 

whats diff between ormal down pipe and ppp one? i want more power lol so my mates say decats lol

 

normal downpipe has a power stangling,thick mesh of a cat for the exhaust gasses to pass through. A PPP one has a less thick 200 cell cat that allows exhaust gasses to pass through it with greater ease. Plus you stay mot/police friendly!

 

beat me to it, if you replace the up-pipe as that also has a cat, this will increase spool up i belive, you will also need a remap to keep everything safe

 

Sorry merlin. Up pipe is a good way to go! Then off to the mappers for more horsies!!! neeigh!!
