Whats the best/cheapest way to get a bigger and better sound from stock 335 exhaust?

gamma335i · 07-23-2008, 12:36 AM

I know little about modding cars but I'm interested in what can be done to get a better sound, for not a lot of money, what are everyone's thoughts?

There you have it.

delete resonator is a very easy mod

Hate to say it, but if you don't have 29.2, you could upgrade, but then you have the lag, throttle closure, rattling sound issues.

Cheapest way would be poking a hole in the exhaust. One of my old cars had a one inch diameter hole in the back it sounded like a super car. It was so loud I couldn't bear it. Is that what you want?

haha, correct me if I'm wrong, but won't this destroy the backpressure?

SV Concepts III · 07-23-2008, 11:56 AM

I'd recommend the Active Autowerke High Flow Stainless Steel Cat Back Exhaust System if you are looking to upgrade the sound, looks and performance. This is a complete bolt on cat back system that replaces all of the stock piping with high flow stainless steel piping that improves air flow, sound and reduces weight. The great thing about this exhaust is for the price of many muffler only systems, you get a full cat back that is an easy bolt on.

Here are a few shots of the display unit we have on our wall:

That was a 84' 300ZX I had in college. I did not purposely poke a hole in it, but the exhaust was so old so it burned a hole by itself next to the exhaust tip. It was amazing how loud that little hole could produce. What's wrong with soy sauce and chopsticks on a old beater?

Azrielsc · 07-23-2008, 08:27 PM

Do this:

Removed the secondary cats and leave the rear mufflers as they are. Louder

Is this your car? Any sound clips?

Azrielsc · 07-23-2008, 08:43 PM

No sound clips though... Never recorded it as no one else has driven the car. Feedback from mates is that it does sound louder than the miltek exhaust.

sambonator · 07-23-2008, 08:44 PM

Did you delete the resonator too?

Is there any droning when cruising? I installed the borlas and in addition to shelling out $900 plus $150 for the install I got a horrible droning when cruising on the highway

.

Thinking the secondary cat delete with the stock mufflers (which apparently are designed to and do a very good job of eliminating drone) might be the way to go since I love the stock E92 exhaust sound (coupes have no resonators I think), just stock its too quiet for me.

+1

Straight pipe!
Just keep the mufflers on for show and remove the mid-pipes!
then you definitely be LOUDER

Hi Sambonator, if you mean the resonator being the x-shaped box closer to the mufflers, then no, they were not removed, only the secondary cats and replaced with 2 straight pipes as shown in the photo above.

The secondary cats (removed):
