thoughts on flowmaster super 10's

9mph on a muffler delete? Come on.

i posted the link to the thread, and i know the car personally...i wouldn't have believed it either unless i saw it with my own eyes. spintech's flow terribly. i know other people who have claimed .3-.5 drop in ET by going from spintech to a proper muffler too.

I'm all for better times and believe he ran faster but I don't think people are running a half second faster just from a muffler swap, there had to be other variables involved? I mean if all I had to do was throw a cutout (i.e. muffler delete) on to gain a half second in the quarter everything I own would have one, I'm positive your right about flow and picking up some time but if it was .5s that thing must have damn near been capped off lol

i absolutely agree. i suppose it's worth it to say that all the combos i've posted about were much more than mere bolt-on-only trucks. one is an 11:1 383 genI with trickflows, the other is a 400+" genI with brodix heads, etc. so these combos were probably being really held back by the restrictive spintechs. my combo that picked up 2mph was a run of the mill 370" genIII build.

Fact is a lot of facts are left out of this equation.

I've done plenty of testing over the years to see what gains are to be had with what mods and a muffler or lack of exhaust is not going to net you 9mph. Other shit was skewing the equation

Damn all those times I went 12.0-12.1 n/a I had a spin tech I could have ditched it and been solid 11s.....doubtful

Honestly, based on our findings, I believe it would have been worth trying.

^Just turn the boost knob up



I had a 3 1/2 " Flowfaster Super 10 on one of my setups, and it sounded like poop. I also had a 3" SLP Loudmouth muffler and it sounded like dump, I switched to a Magnaflow and loved it.

That was two years ago before boost haha. Ironically I went the same et and within .5mph with the true dual SpinTech and with the cutouts open.....

weird...i suppose we could chalk that up to every combo is a little different. i'm sure there is more to the story on my buddy's car, but the findings were consistent with others in the group.
