Freeflow Exhaust -

[Toby]

BIT OF HELP: I CURRENTLY HAVE A RACTIVE BACKBOX ON MY CAR (MASSIVE THING) WHICH I BOUGHT WHEN I WAS YOUNGER AND FOOLISH AND TOOK MUCH HARD WORK TO ADAPT AND FIT ON. IT IS JAP STYLE BUT AS IT'S SO BIG AM I LOOSING BACK PRESSURE? I WANT TO GET A CAT BACK SYSTEM TO HELP HER BREATH DOES ANYONE KNOW WHO CAN SUPPLY ONE AND WHAT BORE SIZE I SHOULD GET? ONE MORE THING, IS IT WORTH ADAPTING THE STANDARD TTE BACKBOX SO THE CENTRE EXIT IS WIDER (WELDING) SO IT CAN BE USED AS IT IS QUITE TASTY! CHEERS EVERYONE

toby on a n/a car a free flow exhaust is wat u dont want. u loose back pressure leading too loss of torque and power. i dont honestly think that u are loosin a hell of a lot though u are loosin some through ur back box.. u do still have ur cat in place? this will keep alot of back pressure.

ive a blitz nur spec from a glanza on mine and it runs super jus keep the silencer in.

yeah i still have my cat. Do you suggest i levae it on. If im to keep my backbox shouldn't i increase the other exhaust parts, ie everything but manifold? By the way cheers for yoyr info on the 5efe, really helpful and will use it to my advantage!!!. tobs
