Default new single 3.5" exhaust

the new th350 is going in soon and the old exhaust wasn't going to clear the different shaped pan. so i built this new system with a single 3.5" bullet muffler. it sounds insane! here's some pics and a video









and video, sorry about the pic quality on the video. the sound turned out ok though

Wow! I am assuming that the 305 is not stock...? It seems to rev up really quick. I like... :-)

haha, for the moment yes. been 1.65 60' on them before (not necessarily this one) so i'm just gonna trust it for the moment. it's got a solid pinion spacer in it so we'll see how it goes. i know for a fact it's gonna HATE me when i launch off the transbrake with the new 4000 stall converter!
