MK4 twin system exhaust - possible?

[HOLEIN1]

just wondering if anyone has an exhaust setup with dual tips similar to the MK R32?

have seen most of the guys here have just the one, but not sure whether this is due to difficulty, price, sound or whatever

if anyone has or seen anything like this, post em up

I reckon you can buy the rear valence for an R32 from the dealer and get a back box made or buy a system.

I'd spend money on a chip first though.

The man is right - get the chip first.

I don't know why you would want the dual system - you will lose backpressure, and the extra weight..

I agree with DIDZ. The twins look cool but is of no beneift. In saying that - carshine in Melb do them:

Is there room behind the rear bumper for it?

I had a look on my a3 and its very very tight there. I really want twins though

Didz - Backpressure is a myth - You do not want backpressure under any circumstances, even with an NA motor. And besides, a couple of extra tips coming out of the same muffler would have no affect on anything.

The on car shine does I think is still a single muffler, just a pipe that runs around to the otherside...

im pretty sure miltek makes a duel system. there was a white mk4 for sale in glen waverly with this system and he loved it. i still prefer the single

Backpressure is not a myth. You do need some but at the same time not a massive amount. Otherwise you could put a 5" straight through exhaust on your car haha, i know im exagerating a bit, but its just an example to say backpressure does make a big part in torque figures high and low end.

I'm lead to believe the turbo will produce most of the back preasure that's required as it also acts as a muffler too. I would have thought having a bit of back pressure beyond the turbine would also help generate force to spool the turbo faster?!?

Note: I just heard this - not sure how true it is but it kinda makes sense too...

Nah; backpressure is a myth. The quicker and faster you can get your exhaust gases out of the engine the better for a turbo car.

You never need backpressure; ever.
