Come back to this review down the road once I've installed and car doesn't really get driven much this time of year anyway but it's for as the build quality and attention to detail is everything I've come to expect from killer bee everything is 100% absolutely flawless and perfect can't speak to the fitment yet although I'm sure that will also be on point but as I previously mentioned I have not had time to install yet running a tomei equal length right now had it on the car for about 4 years now was very reasonably priced was really great for the price but it's certainly starting to show its age was also curious to see how it would change my torque curve in the middle of the band might even drop in and overlaid before and after Dyno graph once I get a chance to put it in
