I got mine from completeexhaust.com Goto their web site to get the phone # and give John a call there. He's real friendly and has great service. The packs were $322 shipped to NJ by UPS ground AND he shipped them out within 20 minutes of me hanging up and emailed me a tracking #! UPS says they will be here Wednesday and I ordered them on Friday @ 5PM. Can't beat that.
He also had the catted X's for $375 but I opted for an MRT catted H from ninosport.com for $460 shipped because I wanted a deeper rumbling sound and a stainless midpipe so I don't have to worry about it rusting out.
Yes, I can validate this. Completeexhaust.com has a special deal going still for about 300 dollars plus shipping for magnapacks or magnaflow catbacks. I had mind shipped to chicago for 318 about two weeks ago. You need to call them to give you the special price...
I went with the 'flows and catted x. But then again I have a vert and I'm right out there with the top down. Plenty loud in the open air. My car doesn't get driven in the rain so the top is always down. Plus I'm an old bastard too.
