Default Popping noise in exhaust

Just installed Milltek Superduals. When I accelerate quickly in 2nd then let off the gas I hear a low sounding "pop-pa-pop-pop." Is that normal or a leak of some sort?

2001.5 Tiptronic - Stock, except Milltek pipes and Milltek DVs.

THANKS!

Default i got that also w/ the G2..did u install yourself? the problem is the exhaust rubbing up against

a heat sheild. Mine was rubbing up by the Y divider, i just had to reajust....does it make the popping noise more when the engine temp is hotter, cause that would make sense....and mine did it mostly under decel. this happening w/ the superdaul makes sense also cause i've heard that its almost too wide under there and may rub.

Normal for a performance exhaust system.

This may it rubbing, but just pretend it is a cool backfire noise. Myself, I love it!

Is it an off-throttle burble, because that's one of the nicest features of that system.

naw. The off-throttle sound is just monsterous. I LOVE IT! Just the knocking between shifts was a bit suspect. I'm gonna go to a pipe shop and have an adjustment. I think it's hitting a control arm down there.

You have to give the pipes enough clearance because it expands when it gets hot.
