Does anyone have this setup? Im getting Kooks LT's with ory . I currently have a flowmaster 80 series 3in catback with a 3in flowtech cutout. I have heard alot of people say it will be too loud if I keep the cutout open. So what if I have it come out the flowmaster and keep the cutout closed? I know that the flowmaster is restrictive. I just want to use it to keep the noise down. Is anyone currently running this type of setup? Do you think it will sound good like this?

I got the flowmaster and the LT's and ORY. ALot of people don't like it cause of rasp, but i say its not loud enough. I love the sound. It sounds like just a muffler at idle but when u get on it it screams.

Thanks for the reply. Got any sound clips by chance? I dont want to just toss the Flowmaster really. Its barely had anything flow through it due to the fact I currently runt he cutout open all the time.

I had Hooker Long Tubes and an off-road Y-pipe with the Flowmaster American Thunder Catback and I didn't like it. It droned really bad and it was annoying. I think the problem with it is that it's loud at all the wrong times. It gets really quiet up top compared to other mufflers and it's really loud/deep in the lower RPMs, which is why it drones so bad. I would prefer the sound of the cutout to the sound of the Flowmaster.

I have the Flowmaster 3" cat-back with Dynatech LT's. The above statement describes it perfectly.

i have the flowmaster muffler with headers and ory, I personally think it sounds like hell . It didnt sound that bad when it was all stock but after heads and cam, it sounds good reving and all but drivng it in low rpms just makes a farting sound in the muffler, really high pitched. On stock tune i gained 24 hp opening up the cutout.

Thanks for all the replies guys. I am going to have the flowmaster hooked into the LT's and ory . I just cant afford a new exhaust now . Im paying about 2000 bucks for Kooks with ory , installed with a good tune and dyno . If I dont like the sound of the flowmaster I could always open the cutout until i get $$$ for new muffler .

Its gonna be surprisingly quite on the highway, my car was louder with the stock manifolds and gutted cats with the flowmaster than with the headers and ORY.

I have the Flowmaster 80 Series with the Hooker LT/ORP and sound like ****. It rasped so bad, I was embarrassed to give the car any gas. It makes a V8 sounds like a ricer and hated the sound.

flowmasters do NOT flow. and they are extremely loud. inside of the car will sound like a helicopter is riding on your roof.

I have SLP LT's ORY and the 80 Series and I think it sounds bad ***. I can spin the tires at a 20mph roll now too in an automatic which I could not do before.

What do you think about borla? I have the borla cat back and it sounds real good. Now that I put the 2.75 diameter g2 y-pipe I can feel the rear wheels spin! But the only problem is a little stutter noise the car makes after I installed the y-pipe : But when I accelerate it goes away, and you cannot hear it from the outside of the veh only on the inside. Does it have to do anything with changing the EGR valve?

your power cam from headers and no cats.
i have seen 15RWHP on a head/cam ls1 car (cutout) over a flowmaster
ive seen 20RWHP on a hot cammed lt1 (cutout)
same car with a dynomax ultra flow only picked up 5hp with a cutout and lost torque.
others have posted the same.
