A must do if you want to be able to have a conversation in your cabin with the engine running.

Pictures!

I wants!

Welds are not picture worthy but at least the tips are aligned and you get what you pay for

If I was doing it again I'd just buy the WORKS AB-M (that isn't even for sale yet).

how much did the resonator cost you? considering it

Whiteoutjames · 01-02-2013, 12:19 PM

It was was around 60 before tax. Maybe get one that is straight through but offset to center it on heat shield but happy with the turn out. It makes me wonder why both pipes get muffled on most systems

I have the Mach V Dual muffler delete, and it's too loud for me. I'm thinking of putting in a 14" magnaflow like you did as well. Did it really decrease the sound and drone a lot? Currently the drone is unbearable!

Can't do a before, and come to think about it I won't do an after, cars parked for the winter. Trust me if you are at the point where you'd rather go back to the stock muffler and would feel guilty selling the delete to some one, then get a competent welder and get the 14" magnaflow

Ya it eliminated the worst drone. Decelerating from 4000rpms was when It kicked in. Now there is a whisp of drone around 5000 but it's nothing close to the original muffler delete. I can't believe that no one mentions the drone in the muffler delete reviews. They just say it's loud

blkwrxwag · 01-04-2013, 10:56 PM

Thanks for your input... I'll see if I can find a local muffler shop to do this. I don't mind loud when you step on it, but it should be quiet when you are just cruising or decelerating.

blkwrxwag · 01-05-2013, 01:49 PM

Had mine fixed this morning. Now the sound is perfect and all the drone is gone.

Whiteoutjames · 01-07-2013, 12:41 AM

Like I say ugly welds, my concern now will it be too close to plastic. Can someone measure or take a quick pic to see the clearance between muffler and backup lights? There looks to be around 4" but I don't want to explode my bumper from excessive heat

Thobjo · 02-17-2013, 11:46 AM

Just installed it and i would regard it as quite a lot of drone.
Anyone who has noticed this toning down after a while of use.
A bit to muh right now to get used to.

jshadeck · 02-17-2013, 12:20 PM

I dont have a berk, but a custom muffler delete. And ive noticed on very cold starts the exhaust is biased to all come out one tip (path of least resistance). Now i see these pics of a "muffled muffler delete" and im wondering... The added muffler is only affecting one tip, and if the berks are biased as mine is at idle, between the bias and the added resistance of a muffler, wouldnt this further bias the exhaust all to ur one tip?

MrTranxD · 02-17-2013, 12:30 PM

To those of you that just installed it, after a few hundred miles, it quiets down a bit. used to be unbearably loud. but now its bearable and im used to it. sounds great.
