@spmufflers: This went viral on reels so TikTok do your thing Custom valved exhaust set up built by one of our customers, giving the best of both worlds. Quiet mode for regular cruising, “track” mode for when he wants it louder. Valve placed after the first small muffler to refine the note on “track mode” #exhaust #exhaustsound #exhaustcontrol #muffler #viral

Joe :

Ppl in the comments not realizing how modern performance cars already use valved exhaust setups from the factory. Almost entirely for noise control

user1942450417686 :

Being installed after the muffler defeats the purpose of cut outs

Hennis :

doesnt that effect the turbo if you close the valve?

Bmullens23 :

Track is supposed to be open header not this lol

Scott Myers :

it would be cool if it was done right don't take your car to them

Mark McKeehan :

After the muffler! That doesn’t work

Mendoza Juic3 Carlos :

Wow the weld is amazing

Poppy :

The caption isn’t accurate. In my opinion open would be before the muffler for best TRACK performance.

Chuckles :

We got a whole generation thinking active mufflers is a new concept

Dilastkgarie :

The Secret is out😂😂😂

Tenrawjt_93 :

So if we look closely at this exhaust system, it is connected up to the heads. It comes down for a two into one and goes directly to this muffler, and all this flap does is while it’s closed, be restrictive and cause a crap ton of unnecessary back pressure and then when it opens up, it allows the natural flow of the exhaust to happen. There is no performance gain, but when closed absolutely it is hurting it as a matter of fact, actually there could be performance gain as a normal exhaust, but this flat being right here is useless in this particular exhaust design because it’s restricting the motor unnaturally like I don’t know any race cars that have this.

Gogleye :

I don’t hear any difference.

People not seeing the rest of the exhaust going above this valve and saying “this does nothing” genuinely need to make an appointment with the optometrist.

Apollo big dog cane corso :

This was done over 20 years ago. This is old.

wedgy1 :

Nothing sounds better than Zoomies

StormsNstuff :

Those welds tho

T-RO96 :

So you’re only changing it from coming out the back to coming out under. I thought The Who purpose was to run it before the muffler so you can have open type headers and then close for the muffler.

Librul Slayer :

Do yall make those or is it a pre made valve muffler

Benji Krebs :

Rage bait

𝕸𝖔𝖗𝖓𝖎𝖓𝖌𝖘𝖙𝖆𝖙 :

im curious, whats the purpose of this, im tryna learn more about like, automotive mechanics and stuff, and so im confused, is this to make it louder? its placed after the muffler, so id assume not, so whats the purpose?

user690912 :

Neat however if you really want to eliminate the muffler and all the piping you should have a electronic cutout at the very front on the down pipes or where exhaust comes down from the motor.

ericcaligiuri1 :

before muffler ,makes no sense
