2002 Ford Focus St - Cat-back Exhaust Drone? Roush Cat Back Exhau Review Youtube

Yesterday i installed the novus catback on my focus, but i noticed a lot of drone while accelerating or driving at highway speeds, any idea what could help getting rid of the drone? I really love the sound note and it becomes aggressive after 4000+.

We focus on designing exhaust systems that enhance and increase the performance of your car I have installed the aftermarket roush cold air intake and the 3 cat back performance exhaust on my 2014 focus st I'm thinking about cutting out the resonators and adding a vibrant bullet style and an ultra quiet resonator in their place

The cmt exhaust to take a little work to get rid of the rattles.

I know it always come down to personal preference but any advice is welcome.

I use to road trip my st with an mbrp exhaust very long distances 16.hour drives from eastern missouri to central colorado It was livable but i like a performance sounding exhaust all the time. The mk3 focus st touring edition exhaust brings it when you're ready, but is refined and sophisticated for around town cruising

As the title states, i've got a bad drone at highway cruising speed (70mph steady on a slight uphill) that makes using the car as my daily almost impossible Wife is a gearhead but won't ride in it for any length.

I've been reading and reading and reading, and it seems that with every catback out there, one guy says it has no drone, only to have someone else respond saying the drone from that.

Its all welded shut professionally so i know there are no leaks When i purchased my son's st it had the roush catback on it Lots of interior drone at any speed I would also say it's nowhere as deep or aggressive sounding as the mbrp that replaced.

Hi people, i've had my exhaust fitted well over 6 months now which includes a mongoose downpipe, 100 cell bcs race cat and a mongoose cat back but i get drone in the usual places. Hi all i originally had the cobb turboback exhaust and it was just too droney, ok at idle and nice sound at wot but just daily commuting was too much, so went to exhaust shop with my. I have the roush cat back right now and it’s just too much and i plan to road trip the car and don’t wanna deal. Tightened the actuator back up and all sorted
