hey, i installed this exhaust (2.5" with magnaflow muffler, aluminized) and it sounds REALLY nice going up through the rpms. Well my question is that when i let off the gas or downshift, the exhaust seems to be "bubbly" i guess you could say. is this normal or do i have a leak or something??

IIRC the popping/gurgling is caused by a lean condition when the throttle is closed and the engine is decelerating. Injectors won't make a difference.

<font size="2" face="Verdana, Arial">I was under the impression that the popping noise was due to the injectors dribbleing fuel out when the throttle is snapped shut. At least i thought that was how jackson racing described it. Maybe he was wrong...either way I wish there was a way to get rid of it completely...

do you think a turbo will make a difference?
