Which do you like better? Which ever you choose put the specific muffler that you like and you can even put why if you would like.

spintech by far it is not raspy like flowmaster, although spintechs are heavy they are the best quality muffler i have ever bought. there flow is much higher too than flowmaster.

i will say nothing bad about spintech. ive never had one but ive heard a couple and admit they have a nice tone

but i have a flowmaster sounds great imo and i dont think it flows terrible but ive never stuffed on another mufler tofind out

Depends on what muffler. I have heard a spintech and it sounded good, but i have heard a few mufflex kits that used flowmasters that sounded great. Depends on the motor tho, hotter the combo the better the sound.

My friends car had a single chamber flowmaster on it and it was one of the best sounding cars i've heard. Has abit of a rasp but i like that sound. Straight pipe dumped over the axle had the same rasp and was much louder but the car still sounded good with the flowmaster. Those 1 chamber race style mufflers flow good too.

I had an 80 series on my L98 and liked it. Wasnt too bad. I like my chambered tube much better. I have yet to hear a spintech on a L98

ive never heard one on a l98 either but ive got a buddy that put one on a stock 94 lt1 car and it sounded good

spintech sounds good, but flow like ****.

Here's a video of my current exhaust (spintech on a modded L98)...

that thing sounds nasty! I like it

Car sounds great, nice cam roll.

What can you tell me about the prom tune? I just did a T56 swap in my 350 Z 91 and had promforless do the chip. I have not driven in long yet but it seems like the engine may want to stall. I had hoped these guys knew what they were doing. Any suggestions?

Flowmaster but not the 80 series, I like the 30 series that my Force II has, No rasp and not loud at all. I really think that it has all to do with the motor, If it's stock I think there are better sounding mufflers out there but on a modded motor I like them better then anything else. IMO.

Here's a vid of me a few years ago after I just put the 4" mufflex with the Spintech muffler on. Im running a 383 Miniram with Hooker longtubes.

Yeah I have a hard time believing a spintech will flow as well as a flowmaster. Flowmasters arent exactly the king of flow, but the spin traps arent the most aerodynamic either.

Very nice! But I think you could use some drag radials.

What, and bust open my 10 bolt??? No way! LOL

That is exactly why I'm not going to do that.


Sorry to steer the thread off course.

I really like the sound of my 4" Spintech muffler, but have also heard of the horror storys about how bad they flow. This past fall I picked up a 4" Dynomax ultra-flo round 17537 muffler. I put down 413 rwhp with the Spintech muffler, so we'll see what she does with the ultra-flo powerwise this summer.

I voted for "none of the above".

flowmasters 80 series with 3.5 inch tips, hedman headers, no cat 3 inch y pipe equals muscle car sounds.... very loud and bassy and people think i have a monster underneath the hood...... who cares which one flows the best if its a daily driver, not everyone is hellbent on numbers...... here is my clip

SPINTECH!!! I am running two Sportsmans on my car. They sounded great when the engine was stock but now I have a new set up they sound down right nasty.

My vote is for Spintech. My brother has them on his 05 GTO.

I pitched the Flowmaster that was on my wifes 1990 IROC convertible for a Borla system.

I still like the sound of SLP's single 3" TOTL system though.
