Low dollar single in/out catback info/vids Got tired of being teased about running my stock catback, and probably choking off some horsepower, so I finally swapped it out. Keep in mind I already had a Borla adjustable and a Magnaflow...didn't like the sound of either, so stuck with the stocker for most of the Summer. Ironically, the new setup sounds damn near identical to the Magnaflow, lol...Maybe the new setup will free up a tenth or so. Car went 11.67@115 with stock catback FWIW.
I pieced it together for about 175 bucks total and the car actually "feels" better at most any rpm when driving.
Parts used:
$54.39 Dynomax #54064 I pipe
$66.39 Dynomax #53061 over axle pipe
$25.00 Force Pro-Series 3" chambered muffler (new, but secondhand)
$21.98 Riker 3" 90* elbow
$18.98 Riker 3" turndown spout
Five 3" Stainless steel band clamps (already had)
I did have to make/weld a hanger onto "tailpipe", but was able to use stock rubber hanger. I need to figure out how to keep exhaust from "moving"...It sort of moved around with stock catback as well. It doesn't hit anything, but in last video, you'll see what I mean by "move", lol.
Here's a couple quick videos...
One of car idling and revved, a couple others taken in-car, and another quick warm idle vid...

I pretty sure thats the new muffler thats copying the flowmaster 40s. I heard a story about flowmaster lossing the patent or somthing and a company is now making them in China and selling them cheap. Sounds good !!!

FWIW, remainder of exhaust consists of JetHot 1-3/4" longtubes & JetHot ORY...with an assist by the "baby" 226 cam, lol.

Any vids of yours by chance?
In all honesty, this Force muffler is built almost too well. The pipes are much thicker than any muffler I have ever seen, and are impossible to crimp. I used the band clamps, but still am having a difficult time with muffler pipe to exhaust pipe connections being tight enough, even with 1/2" air gun.

Now that's FUNNY!!! 
I must have watched a couple hundred videos...with several being watched several different times.
Your vids were the ones I kept going back to when planning my new setup...IMHO, almost every crossflow muffler catback sounds the same and still have flow issues due to their design. The single in/single out setup has to outflow any of them IMO.
