Seperate wastegate exhaust

[BaS2]

Whats the forums thoughts on a seperate exhaust for the wastegate, running a chipped S2, no further engine mods wanted. Sounds like the noise from the wastegate exit could be to much for everyday driving, any advantage of coupling the exhausts together before/after cats or going to rear with the wastegate exhaust, will there be flames? or is this mod pointless?. Just had cats back from Longlife in Leeds, cats now blowing so upgrading from turbo to new exhaust. Cheers.

Dont do it, I had it done and was to much noise for me, get 3'' turbo back system and ask them to join waste gate pipe lower down DP thats my 2p, good luck.

I'd agree the noise of an open WG pipe isn't for everyone. It sounds lovely on full chat right enough, but at part throttle when the WG starts to open it sounds a bit pharty.

If someone could engineer an elegant valve (controlled by boost pressure or disabled entirely) that directed the WG output into the main system or out to atmosphere it would be perhaps the best of both worlds.

Mine is too noisy for me, great for scaring the cr@p out of people when overtaking them.

I'll be keeping it though, and sticking a small silencer on it to hopefully 'sweeten' the sound a bit. Get around to doing it sooner or later, just got a zillion other things to do first.

WG sound is awesome! But not really stealthy. On 1/4 throttle you don't hear it.
Think i need to get used to it. If it's still to load after a few months then I'm doing a small silencer aswell.
You hate it or you love it.......
For a "standard" S2 i don't know if there would be a benefit to it. Maybe quicker spoolup. And a feeling that you'll go faster because of all hell breaking loose.

Thanks, going for 2.5" from turbo, sports cat, just had cats back exhaust from Longlife. Leaving wastegate standard, was tempting though.

why 2.5" and not 3"

I was lead to believe standard S2 exhaust system is 2.5" and RS2 is 2.75"

[Jeffer]

3" indeed.
here's a nice example of e screamer pipe Why bother making a long exhaust.

That must be from the US. No way would that car handle now, with all that weight so far forward!!

I love the WG pipe, it sounds mad. It is not very discreet, but i dont really care about that. It the shear noise on full chat that i love.
