hey guys i have a 68 rsss 350 4 speed which flowmaster sounds the best to you.do i want the stock location or the straight duals thanks jeff

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. http://www.camaros.net/forum/biggrin.gif

I just bought the flowmaster american thunder

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!! http://www.camaros.net/forum/smile.gif 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. http://www.camaros.net/forum/smile.gif

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. http://www.camaros.net/forum/biggrin.gif

I have the crossflow kit in my Nova, with a Hedman X-pipe and Hedders...sounds mean as hell, but not too loud inside at steady speeds- and i have very minimal sound deadener and 3.70 gears. no one else has ever complained, either.
