If you got an 05/06 getting a couple midpipe isn't worth it. However if you got an 03/04 it is totally worth it. I put an 05 coupe middy on mine about a month ago and it's awesome. Really gives the sedan a much better coupe sound. The heat shield blocking the driveshavft is the only thing that usually people run in to. Like myself, I found that it was leaning up against it, so I simply took a rubber mallet and bent it away from the mid pipe with a couple hits and it cleared fine. Got no rattles or anything. It's a very simple install and well worth it

What if you have a GT Spec front bar, will the coupe mid pipe still fit with it?

I don't see why not. It should. Some type of pipe needs to be going through that area whether or not you have a gt spec front bar or not. Plus, the coupe middy is an OEM part so it should fit fine, that's my guess.

Just installed mine today, along with HKS muffler (thanks dunglan7), and Stillen Sways. No issues with clearance. Guess I got lucky. With the Hks it sounds awsome, very very slight drone at about 85. Here are a couple of pictures of two side by side.

Yes, it will fit just fine. I have both. See my sticky at the top of the "Brakes and Suspension" forum.

GGRJR wow I don't recall ever doing 85 mph so I never notice the drone at that speed. But maybe someone else can answer the question if it drones at 85mph or not. If it doesn't maybe something is loose.
