I need opinions on exhaust setup.my current setup:-m52 extractors-twin stainless steel bullets/resonator (15" length if i remembered correctly)-E46 330i supersprint exhaust (twin inlet)- 2 x 2" exhaust pipingmy current dilemma is that my centre bullets (oval shapes) are too wide and due to e30 have limited space underneath the car, my bullets need to be placed lower to prevent the bullets from hitting the chassis, by mounting it lower, i tend to scrap almost every bump even when i travel alone in the car. After 1.5 years of scraping every bump in KL, its time to change my current setup.with my current exhaust setup as above, im having drones no matter what speed im travelling, but it sounds great during WOT.Now my goal is to reduce the drones but sounds great when WOT. Any ideas?my question to those who have changed their exhaust system,1) How long is your bullet/resonator?2) Is a single 2.5" piping size equivalent to 2 x 2" piping size?3) Do you have an "X" pipe welded before the resonators and do i even have to bother about the x pipe?I hope sifus can chime in thank you for your timeChris</p></blockquote><p></p>
