I was about to do the 392 cam and longtubes but I wanted to try some longtubes that not mentioned to often on this site. I ordered stainless works longtube and was going to make a video after everything was installed but the idiots at autoanything.com waited until 4 in the evening on the day they were suppose to be delivered to email me saying they won't be sent out for almost 2 weeks so I canceled the order. Now I'm considering obx or flowmasters. The guy thats driving 1 of the fastest challengers on YouTube is running the obx and I kind of want to hear how flowmasters super 40's and flowmasters long tubes will sound together. I'm wondering why nether 1 of these longtubes are hardly ever mentioned?
