Might be trading my OEM exhaust from my 6MT for sombody's fast intentions exhaust that they have on an auto. Are the OEM exhausts the same regardless of which transmission they have?

 

Fairly certain they are the same. I believe that some aftermarket manufacturers will make slightly different versions depending on transmission, but it should be a direct bolt-on (Infiniti wouldn't want to waste money making two different systems).

An OEM for a FI exhaust? That's a damn good trade.

 

80k OEM + 500 hahaha definitely not a straight trade. Considering people get like 200-300 for a clean exhaust I'd be happy to get rid of it all at the same time.

But yea exactly I saw that some aftermarket mfrs make different ones and it threw me off.

 

The only options I've seen for coupes were RAS equipped or not, everything else is the same travel path of the pipes.

 

Any Sedans exhaust will fit a sedan. Any coupes exhaust will fit a coupe and a 350 exhaust will fit a coupe with a 8" extension.
