Exhaust on e90 330i

[yaseent381]

Hi

With regards to the free flow box installed - it had just the one pipe leading into it and then had twin outlet. One outlet was used on the left side with twin tips and then the other outlet using 57mm pipe was run to the right hand side finishing it off with twin tips.
Performance was not affected at all - just great sound.

Damn! Now I'm stumped lol that 4 pipes also puts another thought in my head, very interested to hear how it sounds, but I doubt it very much that someone going to charge me R1300 lol here in Cape Town it will probably cost around 3-4k , will go speak to this guy Don, he makes up custom systems to the spec or sound you want, does some nice work, @vicky can you remember the specs of that 4pipe setup you had like what size piping was it and what boxes were used and was it twin pipes or a single pipe leading into the rear boxes with twin tailpipes? And lastly, did it affect the performance negatively?? Very afraid of that. Sorry for all the questions, just want to go the right way

Thanks man, ok cool so basicly you had a twin 57mm setup splitting into 2 singles at the rear into the freeflow boxes with twin outlets on each box, sounds good will look into this, thanks for sharing bud :coolShake: anyone else care to share their e90 330i exhaust setups and maybe some power figures if there were any gains??
