3 inch ehaust

[quattros2]

Hi everyone,

i'm about to build an ehahust for my s2 coupe. Just wanted to know if someone has done that before, because i'd like to know if puts the 3 inch pipe like the standard pipe over the back drive shaft, well is it possible or does one have to put it undeneath the drive shaft? Does a 3 inch pipe fit there?

cheers

Depending on what power levels you are going for, you can drop the diameter to 2.75" or even 2.5" to give loads of room and keep the exhaust tight to the diff. The only advantage that I've found from this on my car is that it stops the exhaust from booming and has meant that the sound is quite quiet, even with only 1 box - I'm even looking at ditching the rear box all together!

3" is extremely tight, just made some tweaks to mine but couldnt get it to fit as well as id like without occasionally clacking front subframe or boot where it goes over rear driveshaft

3" is no problem. Just tack it together and test before welding

i just got a 3" turbo back done its mega tight over the axle was rattling a bit so ended up having to flatten it ever so slightly. the system need to be super solid as not to bounce off the cv joint

Yeah mine was pretty rigid before, but has a little more give now so rattles a little now so will need to tweak the brackets and rubbers to suit

i put mine UNDER the subframe so no issues on catching the shaft,nor does it foul the road
