Agency Power or BB exhaust?
i just built a twin cone cold air system for a friends 997 this weekend. total coast with crinkle paint aluminum pipe and K/N tubular air filter $230.00 not carbon fiber but looks good and does the same thing............
Did a lot of research last night and now think I may be going to direction of the "After Hours" Exhaust, it is that or the agency power.... After Hours seems extremely light, basically a muffler bypass with resonators and has some really good reviews
