[08' g6 teen]

I have an 08 G6 Base 2.4L and i found this rear bumper for the GXP http://www.gmpartsdirect.com/catalog/frameset.cfm and my main concern is that there are two cutouts for exhaust when I only have one exhaust and will my single exhaust fit in the left hole or is there a way to upgrade to a dual exhaust and how much would it cost to do so?

You can add a GTR dual exhaust..I think after installation its usually btwn 600-800 depending where you purchase from

the bottom valance that has the dual cut outs is different from your bumper.

brand new a dual out back GTP valance is only about $80.

Part number is posted if u do a search. You dont need a new back bumper.
I have the GT-R. Its an awesome exhaust.

Some of the covers that come on the G6 GT coupes have the street edition package and still have the single exhaust it is a GXP bumper just the passenger side isn't cut out. Check around that one may be the same
