Resonator Delete?

Yep. If you change out the stock mufflers on the stock stainless system, the stock resonator can't cut the rasp from mufflers like glasspacks.

Uh, no. Been behind a bunch of SHOs and the rasp is definitely out the tailpipes.

Of course you are going to hear it out the tail pipes, especially if you are BEHIND them

But it certainly isnt created there.

Rasp is created at the Y in the y-pipe.

And thinner, "tin" exhaust tubing like aluminumized steel allows much of that noise to emanate from that point. Stainless is simply better at containing it.

man, you are talking in circles!

Of course the stock resonator cannot "cut the rasp from mufflers"..... the muffs dont create the rasp, and they are DOWNwind from the resonator.

 

[CademiaX]

guess if you like raspy ricer sounds... go for it.

been there done that...

punched out cats, no resonator, big ass aero turbine mufflers...

 

[Clem]

will wraping the y-pipe with heat wrap work to tone it down a bit?

 

[LOUDSHO92]

Not really, just rust faster.

???

I'll type s-l-o-w-l-y.....

The stock resonator is adequate for the quiet stock mufflers. Go to more open/louder mufflers, it will be raspy.

Change to a bigger/more resonator(s), the rasp goes away.

Has nothing to do with the y-pipe.

BTDT on 4 SHOs myself, and dozens of other SHO folks I know have found the same thing.
