wing exit exhaust

Post Fri Aug 03, 2007 12:39 pm

any ony ever seen one of these on an e30? i want to do a side exit but i thought a wing exit exhaust might be a bit different? but what muffler to use to drown out some noise but not too much!!!

Don't bother with a muffler and go straight out of the drivers wing

My turbo placement means I could do this via the battery tray and out through the wing but I wonder if I'll get a car full of exhaust everytime I drive it with the windows down, which is most of the time these days.

My single box system only gets loud around 2.5-3k and then over 5k, idle and off boost it's rather quiet, although my neighbours wouldn't agree

HTH,Mark.

You can just about ( some have failed ) get a 3inch pipe down past the steering and round the bottom end.

If you're going to do this you'll need a tiny back box or not one. If the exhaust pipe is kept really short you won't need one at all.

I spent some time with a racing truck that a company I work with run, it has NO exhaust at all, just a 6 inch stub welded onto the back of the biggest HOLSET I've ever seen! The noise is sexual, even tho it's a straight 6 deisel!

3inch downpipe is plenty for us, only 500/600bhp engines need more.

HTH, Mark.

p.s. if you want a few really loud and cool noises, vent your wastegate to atmosphere, my screamer pipe is just the baddest thing on my car, it scares everyone in a mile raduis!

Our local postie fell off his bike when I boosted past him a few weeks back, he's since been round to see, in his own words "what the fuck was that!"

guess the turbo take out some of the noise?

would be cool!

you could have it coming out the sills if you bought a Y-piece?

maybe i ought to get an atmospheric dump pipe after all, mine still feeds back into the downpipe

Post Fri Aug 03, 2007 3:56 pm

i would have thought no muffler would have been too loud for the road though?

Post Fri Aug 03, 2007 4:12 pm

It's not that loud is it?

is that with no muffler yeah?

Post Fri Aug 03, 2007 4:16 pm

Just the one and the wastegate dumping to atmosphere.

TBH that's not a good clip as I was doing 80 in 5th and should have dropped to 4th for the pull.

5th goes like 3rd @ 7psi, can't wait for more again!

Ideally a system with both options would be the best, some times I want too turn it off, some times not!
