I decided to do a resonator delete because most people here said it adds a little bit of noise when you get on it, but there isn't any drone. The last part was a lie. There is noticeable drone and it gets extremely annoying on all the long trips I do.


I want to put the resonator back on, but I was wondering if there's a better resonator other than stock that will make it even quieter than stock?

best bang for your buck.

Honestly though, you can't have it both ways and the stock exhaust is pretty damn quiet. Why pay more than you've already invested into it. Just put the stock one back on and be done with it. If you want it even uieter, then do a symposer delete.

Just put the stock back on, then get the Ford Racing exhaust. Nice and loud when you want it to be. Not loud when you are just cruising.

I thought people said there was minimal drone with a Reso delete?

I went the other route (mistakenly) and deleted the rear muffler. 6 months later and I can't stand it. Getting it put back and the resonator deleted instead.

Before you throw the heavy, huge OEM muffler back on I suggest you consider getting with a shop and installing a Flowmaster Super 10, I did:

It is as quiet as stock (I was hoping for more noise, tbh), except in the 4500-Redline RPM range & at WOT, then it's not 'loud' it's just that you can hear an audible but low volume 'whoooooosh' because the exhaust is flowing out so fast.

I'm not pimpin' the Flowmaster, just sharing my experience, this muffler is really, really quiet [with the OEM catalyst and resonator still in-place]. 10/10 would *not* know you have an aftermarket muffler. I would get with a shop and see about fabing this thing up, you'll have to get your own tail pipe - or have them plumb the OEM tail-piece back on, there are lots of choices out there. Just wanted to share this because I really don't see any advantage to putting the big ol' OEM muffler back on when this is a very inexpensive (around $75 and better performing) alternative - that is just as quiet.
here's more photos and discussion on it in the 'exhaust thread:'

I ran a resonator delete for 2000 miles, drone? WTF are you driving the car at 1100 rpm???? It was dead silent for me.

If he thinks resonator delete is too loud, any aftermarket is exhaust is going to be "way too loud" for him.

Not sure you can get quieter than the stock exhaust without buying a Tesla...

What RPM range are you at when you're driving? I get some mild drone between 1500-1800 RPM on deceleration with my res delete, but otherwise I can barely hear my exhaust unless I'm romping on it (in which case the symposer is still louder inside the car). I regularly drive ~700 miles round trip between St Louis and Cincinnati and I never have issues with drone. I even took a trip from STL to Cincy to South Carolina and back and had no issues even when going through the RPM range driving up and down the mountains in TN and NC.

I'd suggest putting in a Flowmaster or Magnaflow resonator to replace the stock one if it bothers you that much, or just put the stock one back on. But if a res delete is too much, I don't think you're going to find a "magic pill" to give you a perfect combination of tone and volume.

I agree, stock is the best sounding exhaust for these. Do a sound symposer delete and it is quiet in cabin, which is exactly what I want.
