oscar90 0 Report post Posted November 30, 2009 So slowly dealing to my to-do list and after brakes is the exhaust, so what size is reccommended for a 325i? single pipe, or twin system like factory? what have people typically paid for a full exhaust? I just want a nice one that doesn't choke the car and sounds good! opinions and feedback appreciated Cheers, Andrew Quote Share this post Link to post Share on other sites
Jamez 2147483647 Report post Posted November 30, 2009 I've heard that a 2 1/2" pipe is the optimal size. Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted November 30, 2009 (edited) I paid $450 for a full 2.5" exhaust with a 14" long resonator in the middle. That was from turbo back though, Would be alot cheaper I'd imagine without having to make a dump pipe etc. Edited November 30, 2009 by e30ftw Quote Share this post Link to post Share on other sites

Nobimmer 694 Report post Posted November 30, 2009 Wayney headers onto single 3 inch pipe. One muffler one res. Sounds tuff Quote Share this post Link to post Share on other sites
oscar90 0 Report post Posted November 30, 2009 Headers will be coming! but at this stage my exhaust is rusty and has afew holes, so needs replacing for its rego test haha as much as I like that remus exhaust a muffler shop job will do haha Quote Share this post Link to post Share on other sites
Apex 693 Report post Posted November 30, 2009 (edited) 2.5 twin into twin inlet outlet centre muffler twin 2.5 to twin inlet out let 2.5 at rear. Most of the restriction is in the squashed rear section, you can build a less restrictive system without increasing noise. Should run you $350-400. Also, your exhaust is only as big as its smallest point. Edited November 30, 2009 by Apex Quote Share this post Link to post Share on other sites
bravo 35 Report post Posted November 30, 2009 Als Mufflers do great work. Know their stuff and will design a system to your requirements that will increase performance, not just make more noise. Expect to pay $500-600 depending on the choice of muffler. More if you want wayney or similar headers. Quote Share this post Link to post Share on other sites
