    I have an 04 with a Steeda Catback and Steeda High Flow X pipe. It is a little quiet through the rpms. I have a UPR offroad X and want to install it, but the car was tuned so I dont want to do the mod for sound and get less performance. Would this effect the tune significantly?

    I have a 2.80 upper pulley with idler, Steed CAI,

    Not worth the money to retune until next round of mods, unless your tuner is willing to make the adjustment for you (nice guy)

    You will get more performance out of an o/r pipe not less, also you do not need a retune for it unless your just looking to turn off the rear 02s, which btw check with your tuner because most wont even do that anymore with the new EPA stuff and if thats the case just run MIL eliminators or non foulers like everyone else.

    IMO you are not going to gain much HP with OR vs hi flow cat mid.
    Your exhaust will be considerable louder and attention getting with the wrong folks..mainly LE. It's all fun and games until you get a ticket.
