HI GUYS, MILD DILEMA.

RIGHT WANT TO FIT AN EXHAUST ON MY CAR RIGHT,

I CAN EITHER CHOOSE TO FIT A BLITZ NUR SPEC R (BACKBOX AND CENTRE)

OR

FULL SCOOBYSPORT EXHAUST (CENTRE, UP/DOWN PIPES AND BACKBOX)

OK FOR ALL YOU CLEVAR PEOPLE.

WHICH ONE OF THESE SYSTEMS WILL GIVE ME THE MOST GAIN IN BHP, CONSIDERING THAT I HAVE A UK300 WRX.

CHEERS
PEOPLE.

REGARDSS
BIGGY
