just got my 02 ws6 bout 2 weeks ago. the previous owner had a flowmaster installed thts the only mod. i know from reading on ls1tech that flowmaster on an ls1 sucks. MY question is how bad will it hurt my times in the 1/4. im going to the strip friday to get a base time.

I doubt it will HURT the performance at all.

It wont hurt anything but you wont get the same results as a better catback.

Here we go again.................. lol. It wont hurt anything at all, the car does gain from it and I have dyno numbers from that set up to prove it. You just dont gain as much as other kits out there thats all..... If you like the sound leave it. If you dont or believe in the "it makes your car slower" then change it.

All these guys are absolutely right. Flowmaster will NOT hurt performance over stock (unless you had a Firehawk or SS with SLP dual/dual stock). It's just that the gains are a bit less than the straight-thru style mufflers.

Until you do other mods the FM will not hurt you.... It will just sound good.......

Don't forget the SLP CME on the SS

The CME uses the same dual/dual muffer as the non-CME cars that received dual/dual systems as a Y2Y option from SLP.

There is only one flowmaster that sucks, thats the crossflow. Is that whats installed on your car?

If you like the sound leave it there and just get a cut out.

I bought my WS6 used, and the only mod was a Flowmaster muffler. I had full intentions of changing it to something better, but I'm leaving it.

Damn it sounds good.

im more then likely gonna change it when i get headers. How are the tsp headers anyways?

I have a flowmaster and nothing beats the sound who cares if it's not the highest flowing system thats why you get a cutout.

That's what I did (well...I run two cutouts, but the same idea applies)

i have true duals with sweet thunder mufflers right now and they sound great, but if i went with another catback i would say slp loudmouth, i used to have one and it sounds so good, way better than the flowmaster on my old z28

can a catback make more power than a a pair of 40 series on true duals?

ArcticMissile

Quite frankly no cat-back is going to out flow true duals.

I have a FM on my stock TA. It sounds like a rocket ship. Interested to see what it sounds like when I throw on LT's. Will probably go with a Magnaflow at some point and sell this one for dirty cheap.

run your car at the strip with the flows, add some longtubes, ory and see how you like the sound and performance.

On top of what everyone says, blowmasters are made out of galvanized aluminum and will corrode and rust rather quickly. They tend not to last very long in comparison to those made out of stainless steel (such as Borla, Magnaflow, Corsa, and a few others.)
