Sound tube Delete

[Rapid Red]

In my opinion it does sound better, no "wall of sound" crap that the 70s made popular.

I knew of taking the inner fender well off, just more work to do, so I didn't.

Oh and I have one that is complete, so in 50 years when everyone is looking for them to complete a restore, more $ for whomever gets it.

LMAO me too ......

Removed after seven hundred miles, nut not included. Special pricing for the numbers crowd

Okay so I got around to removing mine, and wow it makes a large difference. For one thing, the exhaust is a lot quieter with the windows up, especially in certain RPM ranges. Secondly, with those certain engine frequencies gone, my music volume magically increased by possibly double? Seriously, I can hear my music at a way lower volume, even cruising on the highway with the windows cracked. Maybe it's just the type of music I tend to listen to, but that intake noise was cutting all sorts of it down without me ever realizing it. The car in general is much quieter in highway driving, and feels much better insulated overall if you have the windows up.

I guess that's the main thing about this, most of the noise that's gone must not really be in the audible frequency range, it's almost like white noise with the exception of the extra exhaust note that comes in with it. The car feels less "powerful" as a result with all that generic noise gone, but overall I think I prefer it. Also, throttle response improved like 1% on my manual car. Perceptible, but only just. Which makes sense, there's only a small amount of air going into that first portion of the tube and reverberating against all the baffles and such. Redirecting it to the throttle where it should be going gives just that little bit extra.

Also, if anyone reads this who is thinking about doing it, don't bother trying to go through the fender well behind the liner, there's so much tubing and crap going through there I don't see how it's any easier than going from the top. Or, just doing big brain time and giving it a yank.

I noticed this also when I pulled the tube on my '13. The first time I drove at highway speed, the speed compensated volume control cranked up the volume to an uncomfortable level. But that's apparently what was needed to overcome the pumped in noise when the tube was still connected. Had to cut back the speed compensator down a few notches.

Just picked up a Dorman expansion plug for $5. Size 3/4 - 7/8, fits perfect into the air box. Had to adjust the nut to expand it a little for a nice tight fit. Washer is large enough that it won’t get sucked in.
Thanks again all

Glad to help when I can!!

Wow what a difference!! No more droning with with my h pipe and stock mufflers. Much quieter and all the sound is out the back.
