I _finally_ recieved my Spec D today, and as far as I know, nobody has ever done a review on it. I figured i'd fill everybody in on this awesome exhaust.

For those that dont know, the Spec D is the cheapo $400 version of GP Sports N1 style muffler. This is a cat-back unit and the muffler is all stainless with non-stainless metal piping (its coated black to detour rust.)

Heres a before video.
also, heres a before pic, from down below:

a special thanks goes out to my buddy mike for pointing out the dangers of a rusted muffler

Heres the box I recieved it in:

as you can see, it's a 2 piece set that came with a silencer, metallic gasket, and hardware.

I was superbly impressed with the overall quality of the unit, as you can see here:

heres a compairason to the stock assy:

the pic doesnt do it justice, but the piping on the Spec D is amazingly wider than stock. sure its kewl, but this is an assy designed for a turbo setup, ill deal with the torque loss untill i get my motor :crying:

during the install, everything fell into place perfectly. the only issue I ran into was bolting the cat to the pipe. the pipe is so thick that its very hard to get a damn wrench on it to tighten the nuts. Mike and I ended up making a D-Shaped washer to allow proper space for us to finish the job.

with the job done, heres what she looks like, from below:

and to everybody else:

On first impressions, this exas is LOUD!!!!! It's probably because i have a dummy cat, though.

Heres an after video, for a taste. Just an FYI, too, that the exas changes sound when it heats up, it get a lot more mellow and kewler sounding.

All in all, I think this exas is great, and I recement it to anyone seeking an effective N1 style muffler for a turbo application. all though, my recemendation only goes as far as fit and finish, as I cannot dictate how much power it generates because I dont have turbo. :P

cheers!

Nice write up. Looks good!!!

wow dude, your gas tank has been owned.

exhaust looks pretty though, for 400 I think I'd get a full stainless one tho. Rust IS bad and I wouldn't trust that black steel.

Hey nice exhaust.. to complete the GP Sports look how about the G4 kit? it will look great with your gunmetal kit and your s13 front end
