Race Only Exhaust

[just_racing]

Guys wanting to know what I should run for an exhaust? At the moment I have a 3" one piece dump/front pipe.

Do you need any mufflers for track only? If so what would you use?

Is there much advantage in coming out the side instead of the back? Obviously shorter but could it be straighter going straight back? Does coming out the side give clearence issues?

well....assuming your racing has no regulations (including drive by noise regs which most Aus tracks do have....)

side pipe and a screamer for the turbo is the best, because it sounds brilliant.

Yes you will have heaps of trouble with clearance for a single side pipe going over the chasis rail, so maybe go 3 pipes side exit like the super taxis do.

Truth is, these 4" monster exhausts that evey car on george st has are plenty

Yeh, be careful your not gettign pinged at the track for noise. Its happening a fair bit in Vic It makes for an abrupt end to the day

hey, im running a 3" straight through with no mufflers and its not too loud so it should be alright for track use only.

but is it rear or side exit sam?

side exit points straight at the noise meters on some tracks like Oran Park, asking for trouble.....

but they sound and look sweet

i always thought a screamer was a particular breed of woman

screamer = extrenally venting wastegate

Screamer = wastegate pipe that doesnt go back into the exhaust, instead just dumping to atmosphere

We have a side exit pipe on our R33 3inch no mufflers We havn't had any problems at QR and honestly some of the road registered cars are quite a bit louder than us.

We had clearance problems getting on some of the hire trailers.
