Yeah, something like that ... they ain't cheap ... to buy or install ... parts are about 55% of the total cost.

 

ZXsaint,

I dynoed where the sport z magazine exhaust shootout dynoed. There is no Z on that dyno that is going to gain 15 rwhp with an intake and exhaust, it just aint going to happen. Borla gained the most at 8 hp. Also if you are at all familiar with vishnu performance, you would know that it is a known fact that their dyno reads extremely low. They have dynoed four different z's, and their numbers ranged between 195 and 200 rwhp, some had exhausts and some did not. I dynoed with cams,intake and exhaust at 232 on their dyno, and 238 after the xede. Which are damn good numbers considering how conservative his dyno reads. I think the cams are helping out just a bit!
