They work to D@MN good! Lol
Well, these things work too good! I was running straight pipes on my truck but needed "mufflers" to be street legal. I thought I was getting one over and buying some cheap mufflers to squeak by state law. But, no. These things took my truck from an obnoxious offroad rig to something I could drive through a retirement village and no one would even know. I would love to leave a negative review but I can't. These little things WORK! My truck is quieter but still has a healthy rumble and is plenty loud when I get on it. I just can't annoy the people at the end of the street anymore while idling in my driveway.

Dampens drone 21/4 outlet 21/2 inlet
Easy to install really helps damped drone down and give a deep tone to the exhaust

Great product and worth the money!
The only reason I am not giving this product a 5 out of 5 is because i ordered the 2.25" diameter thinking both sides, inlet and outlet, would of been 2.25" but it turns out only the exit side is, the inlet side was 2.5". I was able to make it work regardless and the product did exactly what I was hoping for, it took a lot of rasp noise out of my system which is what I was wanting. I will be interested to see if they hold up over time. Overall great product and well put together, it was not cheap junk!!! I would defiantly buy again.
