How do I make My Exhaust Louder?

Pharaoh2716 · 10-20-2009, 11:21 PM

I have a 2001 BMW 330Ci, and I installed a Borla Catback exhaust on it. The exhaust sounds nice, after the car has been running for a while, but I am looking to get it louder. I do not want to put headers, as I do live in Cali and smog test will be a pain. any suggestions??

Remove it and replace with tubing.

Do this.... I had my muffer taken off and replaced with glasspacks (search kpeng exhaust)... at an idle, it had a deep tone....when you step on the gas, had a nice eve deep tone to it... on highway, the drone was ok....
Had the 2nd resonator taken out and now sounds so much sweeter... more like a bmw rather than any other car with a loud muffler... at idle and highway, it's actually quieter than before but when you step on the gas

Well mine has cut-off muffler, ex-owner must loves muscle cars

anyway, try that..
And if you want it louder....put a speaker on muffler. make it loud

1) Straight pipes...remove both resonators
2) Headers and no cats
3) Remove exhaust
4) Get after market exhaust/ ZHP exhaust

He has a catback exhaust.. and probably not best to recommend people buy a ZHP exhaust. I'd be pretty annoyed if I spent a few hundred shipping and installing an exhaust off a ZHP just to have my car sound no different.

I did a muffler delete on my 330 recently and it sounds pretty good. Loud enough, but not too loud and not too raspy. I wouldn't remove the resonator though. I'll try to get some video up soon. It's definitely a cheap alternative to a catback system or even an aftermarket muffler. You just have to pay for straight pipes and labor + some nice tips.

He has a catback so im pretty sure he doesnt want to cut off the muffler.

Get a M3

ZHP wont make too big of a difference on 330, true. Will make decent difference on 323/ 325.

It all depends how loud you want it...
