They make a twin loop catback exhaust for the coupe. I say this because they advertise the product as 06 si. Take a look at their website:
Hy Tech Exhaust----The Leader in Race Exhaust Technology Click on pricing and scroll down you will see the 06+ SI for $850.00 Mugen also makes a twin loop that runs about the same price (unfortunately it doesn't fit out cars - yet.... :). The mugen is very very quiet and sounds good. I would assume this hytech exhaust would be quiet as well. |

I think "lowering the flow" actually refers to the fact that it is a twin loop. Having the second loop I am sure lowers the flow a bit. With that said it will still have a greater flow then stock. The piping is 2 1/2 inch for both their header and the full cat system. On a type R they are quoting 20hp and 22 torque gains. I think I have actually found the exhaust system to replace stock now :) I know king motorsports has been playing with the mugen twin loop for our cars. They have stated that to much fabrication is needed at this point..... This is a great alternative.

In reading the write up on this product on their site, am I wrong, or did I read that they are also offering this with a cat? Couldn't tell from the pictures, it looks like there is a bulge where the cat would be but it seems to be on the cat back side of the flange. What do you all think? From what I read it sounds like with the exhaust and header that you could still have an application that includes a cat, which is exciting to me since I am currently weighing my options for such a modification.

the twin loop design makes it quieter while not restricting flow
