Title: thinking of changing to twin exhaust
Post by: Smiler174 on 24 February 2017, 16:43:58
Hi
I would really like to swap out my single exhaust for twin exhaust ie both sides of rear of car.
will this cause less pressure and less performance or make no difference, or even better the performance.
Would love to hear from anyone who has done this as an upgrade


Many Thanks


Steve

Will make the sum total of sod all difference ;)

You already have separate pipes all the way to the back box, and twin exit pipes both come out the rear of one silencer, regardless of design :y

This.
Plus, back pressure is a bad thing in an exhaust(although inducing it is often the easiest way of keeping one quiet), and the stock system is already generously sized for the small engine it has to deal with.

Technically you'd be adding weight...  ;)

And as Nick says, back pressure is not req, however consistent flow/speed of exhaust gases is for best performance.

Regardless, in a 2.6 omega you're still going to be looking out the front windscreen at the back of the 316d that's just battered you away from the lights  :P  :D

As said, will make no difference at all, if my Irmscher setup is anything to go by.

Does a heat shield have to be put in place above the new silencer ?

It sounds like you are meaning having a seperate exit pipe on the other side of the car.is that correct ?. rather than twin pipes as in 3.0/3.2 style.if so surely the petrol tank would be in the way /nowhere to put box or were you thinking of splitting the pipe after the box and across the back and back out again ? .? .would be a lot of work for no power gain

With Irmscher, the pipe runs between tank and bumper.

And i assume that will also mean an additional cut out / recess below bumper for pipe to exit from.

you will need to cut out the other side unless you get a irmscher twin exit bumper.

Emd.. my irmscher one had a metal plate protecting the fuel tank.

You mean that plate that is supposed to be around the tank, but is currently sat in my boot, having never been fitted ;D

Given that there's never any petrol in it, you might as well remove it and fit a proper sized LPG tank ::)

Remember that its classified (by who I do not know) as her car, and this time of year she keeps it well topped up with petrol for added weight, in order to stop it getting too lairy when the slippery stuff comes :y

My car, however, petrol? Wot dat den? Much the same as LPG really :P
