Can I get an Apex GT spec muffler?
 

Is it possible to get just the muffler? I would get the rest made at a exhaust shop. Or would it just be worth my time to buy their catback vs. the price of the muffler?

Nope, you can only get the Dunk and N1 as canisters only. Why not go with the N1? Damn near the same as the GT but not all SS. Mine have lasted on both my N/A and TII application with no signs of anything corroding or even changing color with heat exposure.

I want an ass cannon screaming muffler. I heard the GT spec was the loudest, thats why I asked.

On John Zanol's HEAVILY modded GTUs, he has the N1, and his car is by far the loudest street driven FC I have ever heard in my life. Even with the silencer it is beyond an ass canon :) Just get a HUGE street port, mindtrain headers straight to the N1 and you are in business :)

i have an apex GTSpec catback coming straight from a full 3inch downpipe. i dont find it to be that loud actually. it sounds weet as hell. im also running a non-stock turbo setup. which with a stock turbo the exhaust will be louder than with an aftermarket T04/manifold setup.

i love it, and highly reccommend the full exhaust though
