Anyone know of any mufflers that are quieter at lower rpm's but sound sweet when you get on it? Kinda like Borla without the $$$?

I run the dynomax ST's along with a Car Sound/ Magnaflow HF Catted H pipe with angled turn downs and it's legal. I called a referee to ask about it. His reply was *as long as we can reach down to insert the probe, it's no problem*

BTW, The Dynomax ST's flow 410 cfm per muffler. the 50 series flowmasters flow 362 cfm per muffler. ST's are quieter at an idle with a deep BB rumble to them versus the flows, yet plenty loud at WOT. I have no 2k exhaust drone either.

I'm moving up to the ultra flows as they flow 1133 cfm each. I need a higher flowing muffler to match my output with N20.
They have the calculator to determine how much flow you need per muffler for a given HP.
All cfm ratings are with a 2 1/2" muffler with center/side configuration.

I need my mufflers replaced next spring also. Joe DaSilva at DaSilva Racing sells Bassani's. I'm getting both muffler's and the pipes replaced. Bassani I was told are stainless so they won't rust out on you. He quoted me at $499 for the muffler's and the pipes.

If Im not mistaken,the factory pipes on 5.0's are already stainless.I have a 93,and mine are!The 3 chamber flows were made to perform like the 2 chambered ones,but they were designed to cut out the drone you get one the highway.(Flowmasters)

I have flowmaster II series with the mac o/r h-pipe. I don't think it's that loud at idle but it really screams above 3k... 92 green gt, where are you in VA? i'm in Norfolk stationed on the Truman...

FYI, Borlas can be had cheaply on Ebay and other online sites.I got my Pro XS mufflers for $75 each on ebay and it was worth every penny. more power than my flowmasters, nice and quiet at idle (even with dumps) and sounds badassed at WOT

I also have the Force II catback mated with flowtech off road h pipe and bbk headers. It's not too loud at idle but its pretty loud at wide open throttle. The 3 chambers also tend to keep the sound outside of the vehicle instead of booming in the interior so you can't listen to music.

3-chamber Delta Flows: Same sound without being over-the-top. Alot less drone than regular Flowmasters. I'm running 3" 3-chambers now. Pretty docile until I slam the loud pedal.

FWIW, I passed CA emmissions with both 2-chamber and 3-chamber setups and Dynomax Super Turbos. All tests were taken with 1 5/8" shorties and a 2.5" inch h-pipe w/2 cats. Havn't tested with the long tubes yet (fingers crossed until jan 05).

I am on the other end of VA. And the cops down here are just pricks. They love being what they are too.(No offense to any police officers on here )

I want a 2.5 catback but havent fully decided what to buy. I would like Borla's or Spintechs. But havent made my mind up.

I wouldn't buy Flowmaster they drone all the time no matter the model, or rpm ! MAC or DYNOMAX are the quitest I've heard! I have 1 5/8 bbk unequals a bassani x w/cats and MAC flowpaths! sounds nice and not as much drone as the rest of the stuff I've heard out there!
good luck!

I hope you know that running an exhaust setup like that is hurting your TQ and HP. it may sound loud as H, but your going slower I guarante ya.
These motors need back pressure to run right.

A real sleeper is the Goerlich's Xlerator. It is straight thru design like the DM but have an 18" body. They are suprisingly quiet but flow as good as you can get. 99% of straight pipe.

Only problem with the Xlerator is that they have really cheap fiberglass packing in them and sound like complete ass after 6 months

I am well aware of that...but my flowmaster broke on one side....and considering winter is here, I decided to drive it like that...for a week...and park it...especially considering I have no money for new exhaust...

Flowmasters sound good when your idling in the street and are revving it to impress your friends, but they really dont make very good power and the drone is aweful. I have them on a stock H-pipe and they sound good, theyre loud and ballsy, but If I could do it again I would get a straight through muffler like Hooker Maxflows/Aerochamber or Magnaflows.
