hey, the flowmaster crossflow sounds mean, but it might get anoying when cruising at one speed, this is a crossflow style muffler which is 2 40 series 2 chamber flow's that they modify and put together,it has the pipes out the back like a STOCK 69 WITH DUALS. if you want something that sounds as good but quiets down when cruising, go with the 50 series 3 chamber mufflers, you will have to go with seperate mufflers but they have a kit for this also, this is the route i would go with your 4 speed and probaly farly low gears, goodluck, summitt racing offers both kits. goodluck

I have the dual muffler system with 40 series delta flow mufflers. It sounds great to me.

I agree with Boodle-man...dual 40's are nice and it's not too loud for me, nor is there resonance in the dreaded 2000-2500 rpm range. Nice tone for cruising, but she really let's you know you have a good exhaust system when you jump on it. I run 2.5's from the headers to the mufflers then 2.25's from the mufflers out the back of the car.

Hey 68redcam, I also have Fmstr 2 chambers in a 350 4 speed. They are music to my ears. Hear it in mi sig. Sound level, not too much, just enough to let everybody know a "Muscle Car" is coming.

I put the american thunder 40 series on me Z.
My only complaint is the resonance inside the car. The system sounds great outside. I have a factory chambered car that is much quieter inside (no resonance), but louder outside.

I have the American Thunder system with delta flows...I have no interior resonance, and it sounds awesome...even gets complements from the Mustang guys!! Getting replacement parts for the system is like pulling teeth, though. I smashed my H-pipe and they wanted me to buy a whole new kit. I finally got them to agree to send me the replacement parts (cost me $130 with shipping!!), but I've been without the car for going on 3 weeks now. Parts should be here tomorrow.

I installed the AT series Flowmaster kit. some cutting of the head pipes, but well worth it. duals with an H pipe <40's>,and dual tails just behind rear tires. Sounds great, with resonance being loud at idle and about 2000rpm. but you know they're flows for sure.
