Alright guys I have no idea who makes this thing. Looks kind of similier to my old J's N1, its makeing me think that this is the circuit version. There are small differences that I could remember in the muffler shape but its been years. I thought maybe a ebay cheapy but the welds are beautiful. Plus this thing only weighs 13.8lbs. Any ideas

 

perhaps custom tubing made with j's muffler

 

I doubt J's would use an exhaust clamp. Looks really cheesy. That and a slip joint spring no less...

 

+1

Custom piping + N1 esque muffler

 

 

I have an N1 circuit spec on my car right now, the muffler is not a slip fit. It is for sale btw!

 

That looks a lot like the FEEL's Twincam single stainless exhaust (5 different types of FEEL's exhaust). At least the muffler looks a lot like theres, but a lot of mufflers look similar . Although there's a few reasons why I don't think its the FEEL's:
Piping looks custom; I believe that strap on hanger thing is only on there demo car; very rare in the states.

I have FEEL's newest catalog but its all in Japanese, so i can have my japanese friend translate to see if there's any description about resonators. If it is, sell it to me I'm trying to go all out FEEL's stuff

Here's a picture of the FEEL's Ti canister with stainless steel piping on their demo car. Note how the piping goes straight after the FEEL's canister and they are not using the back hanger, which is different from yours.

 

The more I look at this, I don't think it is a custom job. If it is, it's a very nice custom job, since the piping is one piece, mandrel bent. Plus you say the welds are amazing, and the slip fit leads me to think that it is possibly:

One of the RS*R prototype stainless exhausts that they made when they turbo'd their drift car, but before they went to their current exhaust. How big is the piping?

I used to have one of the older RS*R prototypes (w/ the carbon fiber muffler), but it had the same slip fit muffler and the same hanger bracket on the muffler. Where did you get this exhaust?
