Uppipe and downpipe noise levels???
Just got an New Perrin up and down pipe and wanted to know what kind of increase in noise should I expect. No other mods other than silencer removal mod. Please post even if you don't have the exact setup and specific brand.

Thanx,
Jun

It shouldn't be much louder. Mine isn't except for the uppipe leak I introduced

With the radio on and windows up you still don't hear the engine much.

My wife noticed no difference at all

You will hear the whoosh of spool up, and the whistle of the BFV recirculating.

If you keep the stock muffler, you won't hear much of a change in the exhaust sound.
