Anyone using one before their muffler to quieten down or deepen the tone? I put on my Longtubes and ORY this past week on my 2011 Sierra and with my heads/cam the Dynomax Ultra flow welded cat back is a bit obnoxious for me. The Ultra Flow is already a straight through design like magnaflow, and im thinkin about a 12" body race bullet in front of it to help quieten it down a tad and not lose any flow at all.

 

Lots of people do that and have said it works some but it could still be a little loud.

I went with a volant resonator, they make a straight through 3in res. Worked prefect for stopping the rasp after adding a offroad y-pipe and magnaflow muffler. It's more money but was worth it to me.

 

Yeah bud im definitely also getting a tad of rasp and some nasty tones when the trans shifts.. ill look into the Volant.. i got the bullet for like 29.99 so i may throw it on and see what happens lol

 

I run 12" bullets before my magnaflows to quiet it down abit and take the rasp away.
really cleaned up the tone

 

Bullet works just fine.

 

To save a few bucks, I would look into the Summit Racing bullet mufflers. They are louvered with fiber packing inside. And the aluminized version is only like $25. I have one as my muffler and its holding up pretty damn well.
