Muffler delete or resonator delete or both?

Grad12 · Sep 10, 2014

I'm looking to get a little more sound (very little - a little throaty you know) and more performance out of my engine. I was checking out videos on youtube with muffler delete pipes and resonator delete. Should I do one? Both? WOuld this increase performance, decrease performance? Does it have an effect on gas mileage as the factory backpressure has changed? Computer problems (again, with the backpressure)?

I drive a new pentastar 3.6l v6 and love it, I've done few mods, but and mostly looking to get a little more performance and regain a little bit of that truck sound coming out of the pipe. Thoughts? Anyone tried it on this engine?

Thanks,

Not familiar with the V6 in these trucks, but I would recommend a bolt-in muffler replacement and leave the resos in. I have not heard of any gains from removing them and, if nothing else, they add more expansion room for the sound and could help to deepen the tone a little. I believe the Magnaflow bolt-on that guys have used for the V8 would work in the V6. I think the pipes are the same, from the cats to the muffler, but not 100% sure. Maybe someone else will chime in? Good luck to you!

Also, if you don't have exhaust tips, you could put a little larger diameter stainless tip on to help deepen the tone.

Thanks guys. I'm seriously considering it, but I've heard from different forums (for cars) that it decreases the gas mileage, is this true as well? I figured more airflow might increase the gas mileage or at least keep it even with the power. This truck needs to breathe!

The fuel mileage, in my opinion, is lost because of a loss in bottom end torque. This causes people to give it more gas to take off and the raised fuel consumption. If you open it up too big, it will lose some bottom end grunt, but a mild chambered muffler will have plenty of backflow to keep the bottom end like stock while giving more power on the top and a better sound. Also, dont forget the larger diameter tips. It made a world of difference on my exhaust rumble by deepening the tone to have more bass. Good luck!

I need to google what the penstar sounds like with exhaust.

Most V6s sound like crap with exhaust. Except the VQ motor. Yes take from me, since my other car is a Supercharged V6..lol. Although the blower whine drowns out the exhaust.

if you really want an exhaust on a v6 then I would suggest an 18 or 22'' magnaflow muffler, and leave the reso's intact.

here is the best video I could find, all the mods are in the video description.

Not sure I've ever heard any body use the words throaty, bass, or rumble when describing the exhaust tone of a V6. I agree with BlownGP, every time I've heard an aftermarket exhaust on anything smaller than a V8, it sounds like it's coming thru a soup can, like those noisy little tuner cars.

You are too kind - here in Texas this is simply referred to as a "fart can"...

I might be a little biased but mine is not too horrible.
This is actually straight pipes no mufflers, no resonator with a thrush glasspack. :naughty:

You guys havent heard the right set up then. Not sure what was on it, but my wife had a 2006 Mustang with the 4.0 V6 and a 5 speed and it sounded awesome. I think it had Flows on it but not sure of series. The tips were Silvertine I think. Anyway, it sounded better than most GTs that I have heard and everyone, that heard it, thought that it was a GT. V6 cars can sound great with the right setup.

Before I traded in the Jeep, I was looking at the Flowmaster HP2 muffler or the HP2 shorty (a little louder /more aggressive ).
