is there any way of upping the output of the 2.7 without going the chip route?
Just looking for another 10-15 hp, not necessarily wanting to chip it. I'd like to avoid that if I could. I don't know of any HP gains from an exhaust, does anyone else?
How about the Bailey valves? Will they help performance any?

Jim De Arras

And Bailey valves *might* affect warrenty also, depends on dealer and situation.

vehicle with one that had an aftermarket intake, downpipes, exhaust, and a stock chip. The mods brought the car up to about 280hp. Of course that is a single data point and not a real scientific test. FWIW

exhaust doesn't affect warranty? (or not as much...)

i did road dyno testing--Awe turbo back exhaust/Sflo intake and stock chip-282hp and 317lb/ft

I would think Drop in K&N and Quality CatBack system would see 10 - 15 HP
