I used to have LM when I had stock manifolds and a cat... it was loud!
When I added LT headers and took off the cat it was unbearable so I switched to a Hooker catback and I love the sound. To top it off I got a DMH e-cutout so that I can make it loud whenever I want... it's great!!!

 

I currently run Jet Hot Long Tubes, Carsound cats, LT4 Hotcam, and the Loudmouth. Sounds AMAZING. The cats really clean up the sound, and WOT makes you **** your pants. Here are some clips:

Vote for Hooker, however biased it may be

 

Looks as though Hooker wins! Where can I find this system? I've searched around and could only find it at ThunderRacing.com for $299. Anyone else know of a cheaper place? Thanks for all the opinions.

 

I got mine from Ramchargers... they don't have it listed on their website but I'm pretty sure they can order it and I think I paid less than that but I can't remember. Anyways here's their # if you're interested:

1-888-293-7267

 

Thanks I will give them a call...anyone else?

 

Looks like the Hooker has this one by a long shot
