Berk Technology Dual Exit Muffler Delete Questions - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

JohnAyySays · 04-03-2014, 07:04 PM

Hello everyone! I just wanted to hear different opinions on people's experience with the Berk Technology Dual Exit Muffler Delete. I am currently about to pull the trigger on this mainly because I want something cheap but also to make the car sound more alive. I was going more towards getting a full headerback system with the Perrin 2.5inch Catback mainly because of how people talk about no drone which I do need seeing how I daily drive my car.

My question for owners who had experience with the muffler delete how bad is the drone? I've heard that adding a resonator will eliminate the drone. If so what kind of resonator do you guys recommend? size of resonator? I honestly just want to be able to carry a conversation in the car during cruising speeds and listen to my music normally without turning it up all the way. Thanks!

I had the single exit and it was too much. I got it for the same reason, cheap and I needed to hear my car. I regretted it and sold after 3-4 months. The dual exit is supposed to drone a bit more even.

I came from a sti running an invidia n1 catback with a hfc downpipe and no resonaters what so ever that i loved, so my definition of loud is pretty high. I had to either blast the radio and it was hard to hear a conversation. A phone call was basically impossible without almost yelling.

Maybe look at the nameless track pipe with the muffle built in?

Ooo okay! Yea I've been thinking of just welding on a 14" or 18" magna flow resonator like others have been doing to get rid of the drone. What do you think?

Maybe. I havent really dealt too much with resonators myself. I know they can reduce rasp a bit, not sure how much they help drone. Maybe talk to a local muffler shop? I know @PMok has had work done at Neal's Muffler over on the corner of Grove and Redwood and they seemed like good people.

Another option may be a custom exhaust? I am going that route as it is usually cheaper than production pieces ($300-400 for a catback).

Edit: one thing I forgot to mention is the drone happens at lower rpms. Around 3000-3500 it tends to get better. I have an AT so at 75mph im only at 2300-2400 rpm. I know the MT is higher so it may not be as bad, around town would depend on your shift points and cruiseing rpm/speed.

Thanks for the input! I'm still debating whether I want the muffler delete or going with either the 2.5 or 3 inch Resonated Perrin Catback Exhaust. I'm pretty sure you've been to more meets than I have in the bay area but have you heard any of the Perrin exhaust?

The 3" is a bit raspy n/a even with a resonator, but sounds pretty good. The 2.5" sounds nice, but is a bit quiet with just the catback. slap on a FP or OP and I think it'll sounds hella good and definitely is worth the money. Another great option is the resonated FT86-Speedfactory (whatever one is dual exit). That is my personal favorite.

the srt 2.5" midpipe with custom muffler delete I'm selling didn't drone

unvevo · 04-05-2014, 02:35 AM

I love my Berk duel muffler delete I think it's the perfect sound in the low end. It does lack some sound in the higher RPM's. The only drone I get is from when I engine brake. It gets pretty loud in the cab. The tone is really low. I get asked if it had a v8 a lot. Idiots lol.

Absolutely, only when down shifting do you really run into problems with drone. Even then you can still talk easily over it.

If you use your car daily, I would use regular exhaust system with resonators.
