Well I got my shipment from Brenspeed last night. I got the mac axle backs and the tunable induction intake (Demolet) in titanium with the green filter and last but not least the SCT Xcal tuner running 93 octane tune. I installed the macs last night needs some very minor adjustments and just finished the intake and the tune and I will say that this is a totally different car now, I am just amazed. One quick question, I don't know if it is just the macs or if all after market exhaust do it but does anyone get the gergle kinda pop noise when you let off of the gas , kinda hard to describe.
At low RPM's you will get that sound when letting off the throttle with aftermarket exhaust. It is normal, don't worry about it. I happen to thing that "gurgle" sounds mean and nasty.
