Re: Muffler Question
Dunno how quiet you want but a 70 series Flowmaster may work for you.

Re: Muffler Question
Just went through this myself.
I have Corsa DB mufflers with an x-pipe. Have a 383 stroker also with headers. Exhaust was very loud. It did sound good, but it was just too loud at my age. Have three layers of sound deadening in the cab and didn't phase the exhaust sound. Took it in to the exhaust shop and had turbo mufflers added, in front of the Corsa DBs. It quietened it down considerably. Still has a grumble, definitely not "stock" sounding at all, but considerably quieter. Very quiet on the highway, which was a welcome relief. Turbo style mufflers are one step up from stock mufflers in terms of loudness.

Depending on what you're looking to spend, Magna Flow has some very quiet mufflers that still have a low throaty tone. If I had the money, I definitely would have gone in that direction. There are sound files all over the internet to hear what I'm talking about.

Re: Muffler Question
An exhaust cross-over & running the tail-pipes all the way back will also help curtail noise level.

Re: Muffler Question
I have Dynomax Super Turbos, 3" with h-pipe and tailpipes. Nice sound at idle but almost too quiet cruising or WOT.

Re: Muffler Question
A turbo muffler is about the only quiet(er) option out there right now (ie: Walker Super Turbo, Hush Thrush).
Most of the other performance mufflers (ie: Magnaflows) are straight through, not much muffling going on there, about as effective as wrapping a strip of insulation around an exhaust pipe and calling that your muffler. I had a set of Magnaflows on my truck when I went stainless, those where on there for all of seven days before I had them hacked off and replaced with a pair of Super Turbos to get things back to a reasonable level. Just way too obnoxious--And that is coming from a guy who used to drive with open headers without any hesitation. Yes, they where relatively reasonable at idle. But unlike EFI vehicles, carb'd vehicles tend to be in a high idle when you start them up early on a cold morning.... outside your familys, and your neighbours bedroom windows (2.5" pipes, exiting by the rear bumper), makes everybody love you. =-) Alex. |

Re: Muffler Question

Re: Muffler Question
veinbar- i have an extreme cam from comp cams and the requirements are 3000 stall, 3.73 gears, and 3'' pipes and exhuast....i called magnaflow and they told me to go with their 5x8x18 performance mufflers....but that it really wasn't too quiet...lol....
I'm really shooting for a sleeper with cut outs and i like the loud noise all....But i have two little girls and they love riding with me...I enjoy their conversation a little more when i can hear them.....lol bruthaman - thanks, i believe i am going to go with some type of turbo muffler, just can't decide witch yet... axle - dude your story was funny as hell....i had to read it twice and try not to laugh the second time.....but i hear you man, definitely it has to be quiet...the engine alone is loud already..... project77 - where i stay, i don't need people wondering what i have....you know what i mean...plus i prefer to have the loudness with a click of a button..... everybody else - thanks for the advice, i will keep you updated with my choice of mufflers....tomorrow i will be calling thrush and walker.....

Re: Muffler Question
That is one beautiful truck... The fact that it can look like that and and run circles around most makes it the model sleeper. Post a video so we can hear the exhaust you have now. I too wanted a quieter ride, so I grabbed Thrush (Cheap but good) Turbo Mufflers. Thrush even carries a product called "Hush Thrush Muffler" which is supposed to be even quieter with good performance and flow. Not sure of their size ranges...
Since I put my Thrush Turbo Mufflers in, I can enjoy conversations, music, and the sound of my failing rear end... It was exactly what I was after. http://www.thrushexhaust.com/products.html

Re: Muffler Question
3" is going to be loud, and to be honest you don't need it on the average street 383 even with the xtreme Comp Cam. 2 1/2" exhaust will support 550 hp 454 easily, I run 2 1/2" exhaust on my 406 Monte Carlo and it pulls like a freight train. Run the pipes over the axle will keep the noise down and make the interior alot more enjoyable.

Re: Muffler Question
I run Flowmaster 50 series Delta Flow on my 383 with 2.5 inch pipe. It actually sounds really nice, has that old school muscle car sound without too much boomy resonance. It actually fools a lot of people because it's not overly loud and it hides how radical the motor is...well until I floor it anyway, the only give away is the choppy idle.
I know if I had gone with 40 series mufflers I would have ended up hating it. They are OK on a stock truck with catalytic converters, but with a wild motor and headers they are just too much and too boomy for a daily driver.

Re: Muffler Question
I have 2 1/2 on my 408 Roller motor, although I will be going to a 3" pipe on mine, but it is 550HP ... I am getting older and the 2 chamber flowmasters are too loud, so I am going to go to the Magnaflow's myself...

Re: Muffler Question
I put a set of 2 1/2'' Borlas on my 454 and I love them. Whwn I got them I was worried they'd be to loud bc they have a straight threw desigh but They are pretty quite and still have a great sound when you put the pedal to the floor.

I have run Flowmaster muffs and right now I am running Magnaflow muffs. I like the low rumble of the Magnaflows, but they bark as loud as the Flowmasters under a heavy pedal. I have been running my 383 around the country since 1996 and it has worked well for me. I also have the engined cammed up with a Comp Camstroller set up.
