Once the Jet-Hot headers went in, the SLP Loudmouth was making the car way to loud. It's sounded awesome, for about 10 minutes when the popping from the removed cats soaked in.

I ordered a Hooker Aerochamber Catback from Texas-Speed for $325 shipped to my door in 2 days. The Hooker made the car sound more refined and gave a good deep throaty sound. I noticed no power loss.

 I like the Duel straight cut chrome tips better than the cheap looking ones that SLP had on the LM.
