dude you need some shadowline trim-you have dark wheels, side grilles and overall car is dark-get some shadowline!

Ya I cant wait to put mine on however waiting to talk to RPI guys

Already got shadowline; that's a out-dated picture. Waiting to get the exhaust to post new ones. Let me know how awesome your pipes sound

I dont know if RPI reads these boards much or this thread but I would sure like to hear an explanation as to how a 2.5 inch diameter pipe is going to be better than the stock OEM 2.75 inch piping coming out of the muffler-so right after the resonator the RPI attaches and basically converts a stock 2.75 inch pipe into a 2.5inch RPI pipe and then out to the muffler-so a DECREASE in pipe size-Now I have never heard of or seen that-I mean the engine is small-3 L but is making 258hp or 272 in the 08s and already have plenty of velocity with a 2.75 inch pipe IMO-not sure how dropping size pipe can benefit, ESPECIALLY at the 5-7k rpms where velocity is fast enough and flow seemingly would be lessened by a smalller diameter pipe yet the dyno on the 225hp model shows gains throughout the entire rpm range

could anyone tell me how this setup works

Love it! That was like a commercial interruption from your own thread, to comment on his car. Hahahahahaha! So funny.

Thanks for clarifying. I wasn't 100% sure since you had mentioned in only four previous posts in this thread, and once in another thread on the same topic.
