I'm not sure what muffler it is, I told him what I wanted for performance and sound, and he nailed it. This system is a trade deal, I'm installing a system in his boat, and as far as numbers go we don't have a track around here, but on a lonely road it pulls stronger from start to finish!!
I'm not sure of the brand but I'll ask, he refers to them as escalade tips. Thanks for the comments and you guys are right I do need the liners but the dealer wants to much. Let me know where I can get the best price on them, thanks!!
