has anyone tried to do this yet? resonance cancellation tubes

It gets rid of the exhuast drone in cab by cancelling out frequencies.

I just put dynatech headers with high flows on 2004 f150 with slp loudmouths and the exhuast shop talked me into 4 inch magnaflow tips.

holy crap!!! The drone is SO bad, i got a headache! Its good at 2000 rpms, until you push the gas a little. I'm not sure if the tips is causing it or the SLP's. I like the sound, but the drone is NO good.

I was wondering if any of you tried this? I read on another forum they been doing this to mustangs

Think it will work?

 

Well thats a hell of an exhaust system so it will be heard inside pretty well.

I've seen a few set-ups like that on a few GM trucks ( Escalades, Denalis ) back on the GM Forums. It helps minimally, if you really want to kill a vast amount of interior sound, pull your door panels, seats, and carpet, layer down dynamat throughout, re-install all.

 

maybe i'll just take off the SLP's and sell them. IF thats whats doing it.

I want something with DEEP idle, but little when on the throttle (probably can't have my cake and eat it too)

what do you think Darren?

I know the SLP's are under the cab, i might try moving them back towards the box and see what happens too

 

headers and highflows is gonna drone prolly with 95% of the mufflers made

 

I like my Magnaflows but even under the bed and spaced apart 3"s they still drone. True duals, headers, and hi-flow cats theres no way it will be quiet. The Dynamat would help a bit but would be a load of work.

 

i'm going to have to figure something out.

Its like woom..woom...woom in the cab

 

get you some 22'' maganaflows lol

*magnaflows

 

i'm probably going to have to try them.
They already hosed me for 500.00 (yeah, no crap) tips were 140.00

How do i post a sound clip?

 

i wasnt bein serious bc those are the quietest mufflers made im sure but go for it lol. idk how to post soundclips

 

Record a video from your camera/cam corder, upload it to your computer, then to a Photobucket account or better, a Youtube account and host it.

 

here is clip

DUDE!!! That is sick! thats unquestionably the best soundin f150 ive ever heard. How could you wanna change this?!?!

 

Wow that sounds wicked. Who would have thought an F150 could sound like a Camaro SS! Wheres the revs?

 

We definitely need revs and fly by's
