Quad Exhaust System?

gchassapis · 02-19-2012, 12:38 PM

I'm thinking of putting a quad exhaust system on the 35i (Eisenmann) but I can't seem to see it fitting on the standard single exhaust cut-out... Does anyone know if I need to make any modifications on the rear bumper to fit the exhaust system (Plus a 3D design diffuser)??

You will need to modify both side of the stock bumper to accommodate the quad tips.

You just need to cut the bumper to fit it, make sure you go to specialist to do it right.

i did it myself with a heat gun to soften it up and a utility knife.

I have an M bumper and would like to fit the quad exhaust myself. However I drive a N20 2012 Z4. What diffusers fit the Eisenmann quad exhaust? Don't think the stock one fits?

For the 35i use Art No: B5270.00902, this is the model with 2 90mm outlets.

They haven't done anything for the 20 or the 28 yet, but expect something towards middle/end of summer.
