Fitted this today and like the sound and seems to spool up quicker?

The old rear box is a "Race Box" and did have nice quite burble and will be up for sale, was new 6 months ago.

 

My raptor made mine spool up about 200rpm quicker, good exhausts I think.

 

I have a full system 2.5" from the turbo and they are awsome exhausts. make a huge difference over the stock ones. if you havent already I highly recomend getting the down pipe (open bell mouth) as that really helps with the spool up, makes your turbo sound epic as well lol.
