What's the loudest meanest exhaust out for the 335i?

CoolGuyNilo · 05-30-2013, 03:39 PM

How much horsepower gains?
How much does fuel mileage drop?

I'm thinking eisenmann quad racing ?

ken1137 · 05-30-2013, 04:01 PM

nope...HPF but are out of business so you'll have to find a used one. Gains are insignificant with exhaust except for DP, and even then not much.

This one looks pretty mean

zeenon53 · 05-30-2013, 04:13 PM

HPF has top be the loudest....straight pipes, no cats.

tinnsoldaten · 05-30-2013, 04:14 PM

Remus race......

Car comes with a true dual catback exhaust. No gains will be had by switching it, only sound will change. Get your performance down pipes for increased power and an axle back exhaust for a better sound.

HPF was... Turner might be close. There's is basically a straight pipe with bottle resonators ( dont quote me).

1chanc3 · 05-30-2013, 05:25 PM

I don't think I've heard of any HP gains with ANY exhausts. It's mostly all for sound/looks.

I've heard of small hp gains on this car (around 5-10hp) from getting rid of the 2nd cats (which aftermarket catbacks do).

That's right! Forgot about their 335 exhaust.

Szemenyei · 05-30-2013, 05:55 PM

My vanguard is pretty loud..

09BMW335i · 05-30-2013, 05:58 PM

did a lot of research and for the money HPF then Tuner. I modified mine a little bit to get a better fit at the down pipe. I had the first section cut out and made into one tube, moved the flex section.

dirtmaster666 · 05-30-2013, 11:19 PM

Keep the stock exhaust but go cattles dp, cut out secondaries and replace with 1792 vibrant resonators. Lose the mufflers and put 4" tips. Just did it. Wasn't sure at first but it grew on me. It sounds pretty Damn good. Think it would be pretty similar to hpf

Just run open downpipes if you want loud LOL

Tiago@VRSF · 05-31-2013, 01:54 PM

We've had a couple customers pickup our single 3.5" catback and delete the muffler.

It's a great option if you're looking to go deaf

There's really not a lot of gain at stock turbo HP levels, the only benefit is the removal of the cat but we designed our system so you end up shedding over 40lbs in comparison to the stock system. The weight loss is going to offer a larger gain in comparison to the 5-10whp gained from the removal of the rear cats.

Electric cutouts right after dp's!
