I was looking through the Quadratech catalog and came across these, does anyone have them? or know someone who does? What's your opinion of them? Would they quiet the engine down?, make it not so diesel like? lol. Thanks

i messaged someone who ran em a while back. he loved them. worth the money in an otherwise stock 4.0? absolutely not.

if youre trying to quiet the motor down try a quart of marvel magic mystery oil or run slightly thicker oil.

or just turn up the radio.
