Question TSP True Duals Muffler Options

I am leaning toward buying the Texas Speed Rumbler X True Duals. There is 3 muffler options: sweet thunder, moroso spiral flows, and dynomax bullets. I am not to sure what the difference is between them or which one is better. Any advice would be great. Thanks.

I have the spiral flows on my car and think they sound awesome. They are the most quiet of the bunch. Dynomax bullets are the loudest. Not sure about the sweet thunders.

That should help you quite a bit, I have been trying to decide for a long long time and still dont know what I would prefer. Ive heard a lot of clips too. I just picked up a set today for a good deal and they have the spiral flows on them. Ill let you know how I like them after install, dont know when Ill find the time though...honestly I dont think you can go wrong with any of the three.

Yes and I think the best way to look at it is how much of each is straight through, the dynomax bullets are completely straight through and will probably make the most power and be the loudest. The sweet thunders neck down to 2.5" straight through inside roughly and will probably wont flow quite as good. The spiral flows neck down to about 1.5-2" straight through inside with fins around the outside I think so will probably flow the worst out of the three but also the quitest. The power differences between the three are probably almost immeasuable atleast at my power level I am not worried...

I thinking about the true duals also. I was thinking about trying something different. I was thinking about putting some Borla XR-1 mufflers on it. http://www.jegs.com/i/Borla/157/40943/10002/-1# Has anyone tried this?

I have heard of people running them but with them being 5" in diameter you are gonna have some clearance issues without beating in the rear floor boards. Ive had several friends run the magnaflwo 4x9's and that is tight but was doable and only scraped on crazy inclines or bumps without any modifications to the floor. 5" would be pushing it I think...

Just got the duals on this weekend and didnt totally know what to expect from the spiral flows. I had only heard a couple clips, but I am a big fan of them now, the car sounds awesome! They are definitely loud but I love loud, has a nice deep tone and gets real mean when you open it up
