Mine hardly doesnt drone, with or without testpipe..

I had a invidia dual/70RR before.. now THOSE droned your ears off... very annoying.. but the 60rs? compared to the 2 mentioned before.. only about 10% of the drone left!

 

especially with the top up. there could be a difference between the single and dual setups thou. after a while, your body does get used to it (sensory adaptation). new passengers seem to comment on the drone.

 

I just had T1R 70R Em installed, love the sound~ very very nice

 

I just had j's 60rs installed by a shop 3 days ago. Like others said, j's drones between 3-4k, but it's not too bad in my opinion but it does exist.
it's realtively quiet, and super lite.. & looks reallllly cool.
keep this in mind, only very few people can "Really" feel the +hp by only change the exhasut. buy the one looks/sounds the best as simple as that
was going to get t1r instead, but couldn't pull the triger on the new priced blue tip t1r. got a good deal on used j's though

 

haha mike? that you ?
