I was wondering if anybody has fit a 370Z Motordyne Catback on a G37S coupe. Or any information in general. As far as I know, an extension piece is needed, but just wanted any info or tips that could be useful. Thanks in advance!

 

It would fit you'll need custom extensions. Length would probably be around 12-14 in as I ran a tomei on my coupe with 12 in extension.

 

Have exhaust shop weld in extension to make it fit

 

Would I have to weld in an extension? Could I just add an extension pipe? I’d prefer to not cut up and weld the exhaust if I don’t have to, but if that’s what’s best then I’ll do that.

 

You can buy extension piece but nothing wrong with welding in new section since it would allow you better fitment
