Unhappy Remark FT-86 + Resonator Exhaust Drone

Hello all,

Back again with another stupid question. My friend recently gifted me a Remark FT-86 Catback Exhaust with a welded in 3" resonator. I installed it yesterday and noticed while driving to work this morning that I am getting a ridiculous amount of cabin drone anywhere from 2k rpm and up. I have stock headers and have read on other posts here that the resonator should eliminate most cabin drone with stock headers. My question is, is this drone I have "normal" for this setup, and if not, is there anything I can do to reduce the noise? I love the sound at low RPM's, but with this being my daily driver there is no way I can keep this on with the drone driving 50 miles each way every day. For example, the stock Pioneer radio playing at 34 level volume is almost completely drowned out by the drone.

Thank you guys in advance, keep being awesome.

Yes I was interested in this exhaust but was told by owners of it that it’s probably one of the loudest/ raspiest exhausts out there so what works for most people likely won’t for your circumstances. If the resonator is making little difference then you probably need to make it bigger or add another

For reference I have a 2.5 catback (with a muffler bypass valve that is always kept open) with uncatted headers, rest of my exhaust stock and my car has little to no cabin drone- and that’s with the backseats down so I can hear the exhaust more

Damn, I feel so bad not liking it as it was a gift, but I guess I may have to swap back to stock. There's a ~12" resonator welded into the mid-pipe so I'm not sure if there is anything else I can do. It's really only truly bad with the droning when I'm at highway speeds, but that's the majority of my drive.

Yea it’s unfortunate, I’m assuming the catback you’re talking about is the quad tip. Looks cool and I also wanted it but 3”, small mufflers and no resonator as it comes sounded like too much. Especially if you’re unhappy with it with the rest of your exhaust still stock.

If I was you I’d sell the catback or trade it for a decent pair of headers. That way you can have a slight tone/ sound increase that won’t cause drone and more importantly have a noticeable performance gain- would still be putting your friends gift to use

It is the burnt quad tip with a resonator welded on. If it was bought with my money I'd sell/trade in a heartbeat, but since it's a gift I would feel like an ass getting rid of it. I'll most likely just reinstall stock and quietly put it off to the side for a few years until my 86 becomes the "weekend fun car". Thanks for the reply
