My question is will the coupe exhaust system from y pipe and mid pipe bolt directly to sedan muffler?

 

I'm pretty sure the coupe y-pipe is the same as the sedan. Coupe mid-pipe is a direct bolt-on to the sedan muffler, you do lose 1 exhaust hangar, but I haven't had a problem with mine. Where it bends to meet the muffler it sits slightly closer to the ground. You wont get the exact coupe exhaust note, but it will sound nicer.
