Oops, too loud. Pics, video and an offer.

So I finally installed the beautiful Cat Bypass and 1 in 1 out muffler from M&K/Rarlyl8. Fit and finish are fantastic and once I was able to remove the old OEM exhaust system, installation (with the hardware and gaskets provided) was a breeze.
A word about removing the old system: this can be a royal pain in the ***. 24 hours of PB Blaster and plenty of elbow grease resulted in exactly one bolt out of six removed. This obstinance allowed me to fulfill a lifelong dream and buy a Dremel tool. Get the quick release option and a pack of metal cutting blades and wear eye protection. I know this stuff is old hat to many of you guys but raising the rear of the car and placing it on jack stands with my new floor jack and stands was nerve wracking at first but became second nature by the end. This was a phenomenal learning experience.
So here's the catch. It's too loud. I mistakenly bought a cat bypass when it appears I should have purchased a pre-muffler. Don't get me wrong, it sounds great (as the video will attest) but this is not a track car or even a weekend car. It is my daily driver for work, kids soccer practices, etc. so much of my driving is done in the close confines of NYC and quaint historic neighborhoods of Brooklyn. And the sound is so intoxicating that I simply cannot drive it slow. So I have decided to order a pre-muffler from Brian and Ben. Here is where the offer comes in. I will give this barely used cat bypass to the best offer one of you can come up with. But I don't want cash. For example, a couple of pounds of freshly roasted coffee beans or a gently used Porsche book. A Cuban cigar would be nice but I don't drink so no booze. Be creative. Bonus points for people who do not require shipping (I'm not Doyle) or are currently enrolled in college. Send me PM's if you're shy. Remember, this is for the cat bypass only (retail $195). Allow a couple of weeks for me to get the new kit.
Here's what came off:

That sounds fantastic!! Is the rest of the car stock?
I like your trade idea, very creative and reflects on how great the Rennlist community is, will be fun seeing what people come up with.
Looking at the picture of the bypass and the muffler, it makes me wonder if any company makes the 2 as 1-piece, avoiding the need for a flange and gasket/hardware to join them and maintaining a smoother inner-pipe.

Great idea, Robey!
Good luck with it.
I just put in an M&K 1-in 2-out GT3 muffler and a pre-muffler in my car and this is what it sounds like...great workmanship on both by M&K. I got a great deal on the muffler on the other board; it had been ceramic coated and used only once, so the savings paid for the SW chip.

I'm sick of loud cars (perhaps I'm getting old..). I've got an M&K pre muffler and the stock, factory muffler. It's pretty darn quiet.
The nuts and bolts on this car have spoiled me - having spent it's whole life in Socal and AZ. When I removed my cat for the pre muffler, every single bolt came off with ease! They were in such good shape I reused all of them.

It is impossible for anyone here to recommend keeping it that way, from only listening to a video on a computer. I sympathize with you, in light of your usage.
PS-I think the "blue wrench" is a more effective way to remove exhaust, than a Dremel.

Would the 'blue wrench" be a torch? I don't think I could be trusted with that yet.

Strictly speaking your cat bypass is not the issue. I have a cat bypass on my stock muffler and it sounds fine .. not too loud or obnoxious at all. Having said that though maybe you need a premullfer to match the muffler you bought.

No question, but this is M&K's most restrictive muffler (1 in 1 out) so my best (least expensive) option is to replace their cat bypass with one of their pre-mufflers. Which, of course, was the point of this whole thread.
