Quiet fully 3" catback exhaust
You will not be disappointed with the RRE stealth cat-back. Its relatively quiet, obviously stealthy hence the name and it performs very well. I want one. All the cool kids have them in Cali, to avoid the police/ not draw attention.
i bought a similar one to the below link (loud) but had a muffler shop weld in a large resonator and replaced the rear exhaust with a quiet muffler, think i spent 120 buck on top of the ebay exhaust. the exhaust lasted me for 4 years and was still fine when i sold the car last march

RRE Stealth was installed today at CBRD. A tune followed. Results:
The good: At 20" from the exhaust at idle noise went from ~95 dB to ~90 dB. Cabin noise at ~3500 rpm (~80 mph) in the highway went from ~88 dB to ~82 dB. I felt that the quality and level of the noise inside the car were much more tolerable.
The bad: Lost 5 fl-lbs of wtq and 37 whp with respect to the last dyno from 12-sep-2011.
The question: It was 97 deg and humid during the tune, so that may have affected performance. Since the car was not baselined immediately before swapping the exhausts, it is hard to say if the comparison to the earlier dyno is 100% fair (max temp on on 12-sep-2011 in York was 80 deg and the mean was 69 deg). For what is worth, I did not feel a loss of performance between the drive to and from CBRD. I plan to use Evoscan + VD once the temps go down to something more reasonable, and will report what I find.

Most of that power loss you see on the dyno is weather related. I had a 30whp difference in power one time forever ago on their dyno just from weather. Didint change anything on the car at all, just was dynoed on a cool day with no humidity and picked up 30whp
A brief update: Yesterday I ran my car again using EvoScan + VD (Mustang settings). It was a cool 50 deg F. Made 349 whp/311 wtq. This is very much in line with the 340 whp/303 wtq I made back in March before the exhaust swap (same stretch of road). This would point to a temperature effect, and no real losses due to the new exhaust, and consistent with the before/after butt-dyno. Who knows, maybe I even gained a little power with the new exhaust and tune! Car is still much quieter than with the HKS Carbon Ti. Happy-Happy, Joy-Joy!
I love my RRE Stealth. Great sound (if your looking for stealth that is (unless you are still in F & F mode)) and great quality. I have one with a stock tip welded on it so it looks oem
