Ok..so I have searched and searched, but cant find any concrete evidence as to how a set of Sweet Thunders will perform flow wise in a 3" TD setup. We all know they neck down into a 2.5" core that looks like its ready to kill any flow....BUT I know they sound incredible...so does anyone have any PROOF that they will hinder flow?

I was originally looking at Moroso Spiral Flows and I found plenty of people claiming their ETs went up, and their HP went down...some even had dyno sheets....yet I find nothing for the Sweet Thunders...I just dont want to read about the cons after I have them on my car.. so speak now or forever hold your peace..

Im picky about my exhaust note, and I KNOW what the sweet thunders sound like, I wouldnt think you would hear much difference between them and the powersticks, but I also didnt think you would hear much difference between a flowmaster 1 chamber, and a Cherry Bomb 1 chamber knock off and you definately can.

im very picky as well with my exhaust. let a lone everything on my car. but i doubt youl have a poblem with the sweet thunders, and they do sound badass im sure theres other threads that discuss the flow of them vs others but have never read anything bad about them.

Unless you are running 500+cubes then 2.5" is plenty of room for flow. 3" is actually a little overkill but not entirely.

You'll be fine with them, and they do sound badass. I miss mine sometimes, but they were just too loud with the cam. I went back to the Dual/Dual with an E-cutout and couldn't be happier.

Just found out they started making them in a High Flow version with a 2.75 inner core vs 2.5 so that a bit better.
