Does the testpipe helps reducing drones?
I have 63 v2 t1r catback it drones pretty bad at 3000~4000.
If it does, i'm getting one.

Also, my catback touches the rear bumper and about to melt down..
If I change the rubber hanger exhaust to ap1's then will it be solved the problem?

Thanks guys!

 

Can't tell you if a tp would help on your car...can tell you I have a tp and 63mm v1 and have no noticable drone.

AP1 hangers or go to a parts store and get a generic hanger. Otherwise, carefully bend the hanger hook on the exhaust. If you had the exhaust installed by a shop...go back and ask them to adjust the exhaust.

 

I bought a berk and it dropped my droning down a lot, weird thing is that it made the exhaust louder, but I can't hear the difference from inside the car unless the top is down.

 

I have a Berk on mine as well. My Fujitsubo Dual got a lot louder, the drone is basically gone (but i really never had much)

 

How does it sound... im looking into getting a Berk test pipe and want to know if its going to be too loud....attention grabber.

 

Gonna be quite a bit louder.!!!

 

I have the T1R 63 mm V2 with T1R test pipe and I really only have drone about 75 mph. It should help.

 

The cat acts like a resonator so by removing it your going to get rid of a certain drone range at the expense of making the exhaust louder overall.
