Ok ive used the search function and i come up with too much different info. some say it frees up 3 hp others 8+, does anyone know for sure???

 

I dont know about 8 HP, maybe 5 at the most if your lucky, Auto say they really dont feel it, but people with 5 speeds, say they can feel it, it helps more off the line, personly for 5 hp, for $200... I dont see it being worth it

Why not, people pay $500 for a catback exhaust which gives about the same gains.

 

I feel it, mostly in the lower rpm range. It's not like nitrous or anything, but I could definitely tell the difference. BTW I'm autotragic.

 

Yeah, but they were probably also interested in the sound and the look...
