I am beyond unsatisfied with their replacement intercooler pipes to the tune of several hundred dollars. I would like to know their response as to why it does not clear the battery in an effiecient way, and why the connectors do not fit the throttle body. This is not to take into account paying overnight shipping for the correct fittings, going without a car for several days, and having my car towed when the fittings burst. Still after all this the car is slower than before the "upgrade"! This is without a doubt the biggest waste of money on a useless upgrade.

 

maybe you might want to get tuned for the IC pipes. but call gruppe-s if you want too, i have seen plenty of evo's make power with them after a tune. anyways good luck.

 

I use them on my car, but seeing the clearance to the battery, I opted to go to a mini-battery. With that, it works great.
