Installing Zoomers Catback this weekend
 

I have a 2006 A6 Tranny Vett, and I was looking for a catback system w/t x-pipe with no resonance. If you are an owner of the A6 Tranny vette, you would know there really wasn't a system out there. I think Corsa makes an axle back system for $1,600, but their x-pipe doesn't fit.

Anyway, I've decided to take my chances with Zoomers. I'm getting a before and after dyno to make sure that what they claim is true (I'm very skeptical, so I'm spending an additional $150 to perform dyno tests from another tuner). One thing for sure is that I like the sound and the look (which is all subjective). I've already doen the before dyno, my base line is 340 hp with SLP Intake system. Hopefully, I can gain another 20 hp with the system, which is hard to believe. But they gave me a money back guarantee. I'll let you guys know how it turns out. Hopefully by Monday, I can post some pictures of system and post a dyno graph. I'll put by thumbs up or thumbs down pretty soon. Here is the "before" dyno graph.

That's right we are working on Jooyoung99's car test fitting the first 5 systems off our production run. Here are some pictures of the progress... Pictured below are the jigs for the x-pipe section, the muffler and tip assembly and the car ready for test fitting.

RE: Installing Zoomers Catback this weekend
 

Ron, lookin' great... and very familiar! ;) - JooYoung99, congrats on your decision!
These guys are great and really put their heart, as well as their expertise, into their business. They are well-known on many auto forums. I moderate 9 Dodge/Chrysler/Jeep boards and Zoomers has become legend in the LX world of the 300's, Magnums and Chargers as well as making rapid inroads with the new high-performance SRT8 Jeep Grand Cherokee.

I'm lovin' mine and I look forward to your follow-up... when you post your review thread, please be sure to post a link here so we can find it!

RE: Installing Zoomers Catback this weekend
 

Jooyoung99, good luck with everything but I doubt you will need it. These guy look like they know what they are doing and I'm pretty sure your system will come out great. I look forward to see/hearing a clip of it once its all bolted up.

The Verdict
 

My overall rating on the system: 9 out of 10 (I reserve giving full 10 out of 10, if all claims the manufacturer make is verifiable).
First, the system is 95% drone free, not 100%. Between 1500 to 1600 rpm, there are some resonance. But you know what, I actually like it with little bit of drone.
Second, on WOT, it sounds amazing. To compare the sound, it's mixture between 2000 Lambo Diablo and stock. Very hard to describe, you just have to hear it. But I love it.
Third, I've gained 10 rwhp. Zoomers claimed that it gain 22 rwhp. My base was 340 rwhp with SLP intake, and with the Catback, it was 350 rwhp. I'm a skeptic, but a fair person, so I didn't ask for my money back. 2 main reasons (let me know if my thought process is logical): First, the weather was 12 degrees hotter on the "after dyno." Second, I've dyno the car without putting additional miles on the "after dyno." And lot of people are telling me that it takes at least couple hundred miles for the ECU to syncronize with the new modification. I'm sure not whether that's true or not. So, I am going to do another dyno after 200 miles. Interesting thing during the dyno test was that it seems to gain little bit more horsepower with every dyno run. The first run, 3 rwhp gain, the second run, 6 rwhp gain, third to sixth run, it was 9 to 10 rwhp gain. So maybe I do need to put some miles on it to get the full benefit of the system.
Anyway, I'll post some pictures and the graph by tonight. Overall, I give it a thumbs up. Those guys at Zoomers are planning to do a dyno day/BBQ sometime in the near future, and asked me to bring my car. I'll be happy to show you my car if you live near Brea, CA.

RE: The Verdict
 

Here are the power and torque curves of Jooyoung99's car good solid gains throughout. I think with a few more hundred miles on we'd get a few more ponies out of her. Check it out...


Note base line stock and Zoomers was run with a aftermarket CAI (Brand SLP)

A few more...

RE: New Aftermarket Exhaust
 

Nice looking system. Does it work on '07 C6? How much does it cost? Really wish you had 4 tips on there, like that look better. If I bring my car to Orange County on a Saturday can you install it there?

RE: New Aftermarket Exhaust
 

Price is $1399.00 and it works on the 07.. 4 tips are not available but most say the dual tips really clean up the back end.. Ron 949-916-3240
