im gonna be putting mine on the track soon and keep seeing loads of race cars with side exit exhausts



whats the advantages of these?



thanks

was looking into this for my track car (also a S1). I'm put off about the noise limits at most tracks now so have opted for a custom exhaust with swappable boxes etc.

 

Most track days noise limits are about 108DB i think...

So you'll need a Re-packable silencer


As for the side exit its self, i dont think theres much advantage tbh ??

 

might go and have a chat with hayward and scott tomorrow and see what the damage is on complete custom one


as i think i will struggle on the noise restrictions on full boost










and i like the idea of a CUSTOM one, not much of my car is run of the mil

 

I know


Custom would be best

 

Main reason for a side exit is less weight, cheaper, and potentially less restriction for the bore size due to shorter length.

As well as it looking the bollocks, of course

Depending on the track, a side exit can HELP you get past noise limits as the exhaust may well be facing the opposite side to the micraphone that picks up drive-by noise limits

Get a custom 3in side exit made with two silencers, should pass noise regs anywhere and no restriction on a RST

 

Its far from your RST trust me steve

 

In my honest opinion, don't bother. Most people charge you MORE for a side exit even though it's less fucking pipe............

PLus, it's bloody annoying as you can hear perfectly well out of one ear, but not the other............ Get a regular one out the back of the car, least that way you'll be evenly deaf

 

Ive not got an RST so it would be far from mine

But 3in exhaust on his car, unless he got 450+bhp, aint gonna be a restriction is it

 

Fitted one on mine for a very brief moment, it was waaaay to loud and was certainly not a performance upgrade, had zero back pressure which isn't good. If you get one, make sure it's thought out

 

Never said you did and i know you havent

 

do different turbos have different mounting patterns to exhaust?


might get one made with a small interchangeable sectionas i shall be going roller bearing soon

 

im gonna be having a side exit made for mine, but will have an exit on either side.

gonna try and get 2 silencers in too lol
