You crazy loco mon, they look sweet in person. From 10 feet away you cannot tell the diff in size between the MD twin and the Stomung twin; I own them both.

There is one more dual availalbe and one single tip, then we are looking at another couple of weeks.

Happy Driving...

I'm getting the 2.5" single-tip Whisper for my RS, after I do my WRX swap later this year. Can't wait.

Came to this thread hoping for a sound clip, but I guess there isn't anything just yet. I'll keep browsing around!

Look what landed on my front porch today!





Rich, I'm very impressed with the craftsmanship of your exhaust bits. The welds are perfect.

Thanks a lot! Look forward to the DP and posting sound/video clips.

say, would it be possible for anyone to put a review of this exhaust in this format?

http://www.turbomagazine.com/tech/02..._dyno_results/

i know the above is an old review, and you can't necessarily get apples-to-apples comparison, but it would be helpful. I wonder where TurboMagazine put their decibel meters to get their sound readings? Given the dB levels, it seems like just a few inches off the tail pipe? Don't forget that for every +3dB's, that's a doubling of sound energy. And for every doubling of distance from a sound source, you cut your sound by a quarter. Inverse Square law. (You can guess what I'm interested in. :-))

it would be great to have some standard form format, so we can compare reviews...

i.e.
  • Car tested: Stock MY2003 Subaru WRX Wagon with/
  • Manufacturer: MadDad
  • Model: Whisper Dual Tip Cat Back Exhaust
  • MSRP: $679.95
  • Weight: ?.?? pounds
  • Tip Diameter: dual ??mm tips (?.??? inch)
  • Sound Decibel @ Idle: ??dB
  • Sound Decibel @ 3000 rpm: ??dB
  • Peak Horsepower: ???.? Hp @ ???? rpm
  • Peak Torque: ???.? Tq @ ???? rpm
  • Largest Horsepower gain over stock: ??.? Hp @ #### rpm
  • Largest Torque gain over stock: ??.? Tq @ #### rpm
  • Piping Diameter: ??mm (?.??? inch)
  • Exhaust System Construction: Polished stainless steel canister with stainless steel piping

Oh, BTW, that thing looks great...

One of the tough parts about comparing exhausts at idle vs. 3000 rpm is that 3000 rpms with no load is very different from 3000 rpm moving the vehicle. It's amazing to me that about 35% of the guys that have bought a Whisper actually owned something else first. Some of those exhausts were not known to be the loudest but some exhausts just don't sound that great inside the car under load, in particular if you have long commutes...still I guess getting the 3000 rpm db level in neutral is better than not getting it at all. We did have customer tell us he passed a CA. Db test(he challenged a ticked) on his catless WRX. Just made it at 94.5 db with a Whisper single tip. I forget who's downpipe he had, but it was a catless bellmouth. In my mind there are two sound qualities to a catback...one out side the car and one inside. The thickness of the stainless steel for instance can have an effect on the loudness level you hear inside the car....lots of little details can make a difference.

True.
a sound test on a moving vs a non-moving vehicle will give you different results. Also the sound transmission thru a thicker-walled pipe will be less than thru a thin pipe. There are a lot of variables to play with, including turbo size, downpipe, headwork, etc.

Actually, the test that most States recognize and use for vehicle sound control is the SAE J1169.

The exhaust test is measured at about 4500 rpm @ 0.5m from the tip. The specifics of the test can be found at the bottom of the page on the APS website here:
http://www.aps-wrx.com/us_spec/subar...wrx-hoe-r5.htm

I have the 3.5" APS - it's gargantuan and LOUD. But it's going bye bye in favor of the MadDad Whisper Dual Tip - I just got it delivered last week and I the quality is top notch. Rich - thanks for the prompt delivery!
I also love the fact that it looks rather "stock" (no huge tips) so appearance helps to go undetected.

A Review in the above format would be helpful to get a good idea of exhaust - for sound level measurements you do have to specify the distance the microphone is placed from the tip. Since noise level decrease with distance is a significant factor, as well as the RPM of the engine and the sound scale used. "C" scale will give you higher levels than the "A" scale. I believe you need to use the "A" scale as that one is weighted for human hearing.
