[Pele96]

[judec]

I fond nothing on UUC website, same on corsa website. would U be so kind and provide a link? or are U some kinda joker?

[Pele96]

No joke. I found it by doing a search under 335 and this is straight off their website:

p 2007+ 335i


Reflective Sound Cancellation technology for the 335i

CORSA is one of the largest automotive and high-end marine exhaust tuning companies in the USA with engineering and manufacturing facilities in Ohio and a patented, proprietary technology called Reflective Sound Cancellation™. CORSA consults to General Motors, Ford and Daimler-Chrysler.

The result of the UUC and CORSA partnership is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm.

How does it work?

Reflective Sound-Cancellation™ (RSC™) - a non-electrical noise control system without the complication of incorporating the use of electronics or speakers. Essentially, engine sound (pressure) waves are reflected in passages inside the muffler to cancel out unwanted sound waves. The result is a "tuned" muffler that "cleans up" the noise without eliminating the pure sound of power associated with a high-performance vehicle. Using this Corsa technology, the stainless steel Corsa Performance line of mufflers are tuned to eliminate passenger cabin resonance and produce just the "right" sound. .

The Corsa Performance muffler design does not use conventional packing materials, and provides a totally un-restrictive exhaust flow for maximum power output.

The RSC335 is fully emissions-legal in all 50 states.

Construction enhancements include 100% mandrel-bent pipes and TIG-welded seams.

SOUND LEVEL CERTIFICATION
Many statutory bodies around the world currently mandate that vehicles comply with stationary exhaust noise tests specifications - Generally based upon the "SAE J1169 Measurement of Light Vehicle Exhaust Sound Level under Stationary Conditions". California and various other states now have legislation that makes exceeding this limit an offense, resulting in a "fix it" ticket and required testing certification.

RSC335 has been certified to meet the SAE J1169 sound test for 95dB noise limits.

The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983 noise level meter, specifically as illustrated in the diagram to the left. Positioning is relevant, the tests are extremely specific in their scope and must be conducted under controlled conditions.

Thanks.

It's really hard to judge since it was recorded inside. But it seems to provide a good solid sound. A lower tone. Which I like.

Any pictures of the exhaust and tips on your car?

[Nyulak]

Yep.

[Nyulak]

I meant to record video of me moving with the camera outside, but I never got a roundtoit.

[Gen_E92]

sounds great, but seriously not feeling those angled cut tips, looks like they belong on a domestic

[judec]

I may be lame but I still can't find it.

Am I looking on the right sites?

Go onto uucmotorwerks.com and do a search under 335. It will come up..

I'm interested in this exhaust I think. I've always loved their sound. As they say on the site, mild tone and loud at high rpm. Which is true.

I wonder if they'll offer a cat-back soon?

I may take a chance on this exhaust in a few months. We'll see.

[Nyulak]

yes, i let them borrow my car on several different occasions to work out their exhaust. I like it, although I may be biased considering how it's free for me. It serves its purpose well when I visit my father, because he can clearly hear me pull up the driveway between his house and the neighboring building. Helps to have that extra dB or three when you get passed 50 and live in an attic.

[Pele96]

Have you dyno'd your car after installing the exhaust?

[judec]

ehhh...

[Nyulak]

I had a dyno when my PROcede (1.4) was installed in April last year showing 320+HP and 370+ Torque with bad gas, winter tires, and no adaptation. The last time I had it dynoed here (1.4 still) the power went to 330+ and ~400 torque. Both cases had the exhaust, but the first case was the original prototype and the second case used a pre-production model. I think the pre-pro model felt better, but my butt isn't calibrated.

[judec]

buy a butt calibrator

[Couch]

Is there any baffling when downshifting/slowing down in low gear?

Just curious, I love that sort of thing.

[Nyulak]

If baffling means some popping in the exhaust, then yes. I drive by a shopping district on occasion to listen to the exhaust bounce off the walls (too cold to enjoy it now) and I often cruise in first, let go of the accelerator, and enjoy some popping.
