Posted more for archival purposes. Supertrapp sent me a pair of their most expensive mufflers, the polished stainless steel 17-inch model as a goodwill gesture because the black muffler Summit Racing sent me (I initially went with a single system) ended up melting away a small part of my black rear fascia.

I told their customer service rep (super cool guy) that this was my forth Supertrapp system I was using and I guess he wanted to reward me for my loyalty so they sent these babies ($200 each) free of charge. Incredible gesture.
I had the 'trapps installed today using the connecting pipe originally off of my Tanabe Racing Medallion catback. It worked incredibly well because the inlet of the 'trapps are 2.5-inches which allowed them to be adjusted at an angle that would nearly eliminate any restrictive bend coming from the Tanabe section used to host the two 4-lb mufflers.

I knew that my priority of lessoning the exit angle between the Tanabe section and Supertrapp inlet would result in the mufflers coming out of the rear fascia at an angle (not straight) and that was more than fine for me. The closer to keeping a straight flow path the better.

The polished stainless steel (fairly fingerprint ladden at this point) mufflers look super nice and the accompanying body hangers also came polished as well. The entire system weighed came in at 26.5-lbs, or roughly 12.5-lbs less than the dual Tanabe RM and 25.5-lbs less than OEM.

The final product looks much less "in your face" like the huge cans of the Tanabe and leans more towards the OEM appearance (4-inch compared to 3.5-inch). I still love the look and performance of the Racing Medallion but wanted to get back into saving weight. To continue, the performance of this dual 'trapp system has NOT been tested yet by my Tazzo but first impressions are very, very encouraging. Too much rain to go out and have fun with the car doing test runs but I'll be surprised if it doesn't come close to the single Supertrapp I've been running for the past week in which the Tazzo results were VERY strong over the Tanabe which in of itself, was 4-5hp above the OEM system. It's hard to look at how much of the increase in power comes from the Supertrapps themselves or how much can be attributed to the weight savings. In reality, perhaps 75% of the former and 25% of the latter. Essentially, the Supertrapps are nothing more than polished SS cherry bombs with discs to control exhaust flow and thus, backpressure. I decided on using all 12 discs per side because I wanted maximum flow. If I was to go race the car on a track or in such cases where I intend to take the car to the dragstrip, I would remove the end caps and go with the straight thru look which is loud, but certainly most conducive to free flow.
As for sound, I could not be happier. The exhaust note at idle burbles nicely with just a hint of aggression. Nothing obnoxiously loud but definitely lower in tone than stock. Think more bass, just a touch of volume. Once rolling, the feel inside the car is velvet smooth delivery of exhaust note and feel. There is no interruption of the tone right up to VTEC, just a very smooth sound which I attribute to the attempt by me and my tech to keep the pipes as straight as possible between the Tanabe mid section and the Supertrapp mufflers. Once I hit 6,000 rpms, it was almost as if something "opened up" underneath the car and the sound became VERY aggressive with a hint of superbike to it, if that makes any sense at all. Right up to 9K, it sounded like a cross between a Honda CBR and Honda VTEC. Hard to explain but I'll get a wav file or two when I test the system, hopefully tomorrow. I do have a wav. file taken last week with the single and it sounds fairly identical to that, only in harmony.
Overall, a tough mod to get all the loose ends resolved but I'm very happy with the system. Chasing different paths is something I enjoy and I know there aren't many S2000 owners willing to try these mufflers because they're so closely associated with muscle cars but the sound is really what makes these so popular and that's why so many pony cars have 'em. Anyone who has owned American iron knows an aggressive sound is always a top priority with V-8 owners and yet the Supertrapps deliver just as nicely with a four cylinder. It is VERY closely associated with a "race car" tone. It is NOT a sound associated with fart cans or "rat-a-tat-tar" exhaust systems and the look of the tips always seems to start conversations at gas pumps. "what the hell are those?", etc.
Hopefully, this thread will be of some help for those in the future browsing through the search engine looking for Supertrapp info.

 

i am not too sure about this exhaust....im a little uneducated on these.... but umm where is the exhaust outlet.... looks very interesting.....

 

it looks like it is closed Russ

is it supposed to be like this?

 

That is the way this exhaust works. The exhaust exits radially via the discs behind the cap. The cap can be removed for track use. You can also "tune" the exhaust via the number of discs you use.

This should help with the explaination of how Supertrapps work. Below is a pic of my single "race-ready" 2-piece system I will soon offer for sale. You can see the end cap is off and it's straight thru all the way. When I went back to the dual polished look, I asked my muffler tech to be very careful removing this two-piece system because I thought it would make a great "race day" exhaust for someone looking for the most possible gain from an exhaust. My Tazzo backs up the claim. This set up made some serious gains for an exhaust but it IS loud. You can clearly see the look without the end cap, which is the main reason people raise an eyebrow when they see this type of exhaust. They're not used to seeing a muffler without a visible hole.
