Hey everyone!
New to the forum, had my 135i about 2 months now
Have already put on the VSRF kittyless DP's and that made such a difference in sound!
I got a little rattle on the subframe after the install though, tried to readjust the piping to no avail, ended up using the radiator clamps that I saw on e90forum IIRC. Sorted the problem out and cut the drone down to almost nil!
Just wondering if anyone has any experience with catless DP's and axel back or resonator delete? I would would a little more noise but not a huge difference and I suppose my main issue is drone, which is a hard battle being an auto!
Thanks for any advice
EDIT: I have read that the resonator delete doesn't make much of a difference, wondering if this is still the case with downpipes installed?
