muffler choice? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got dual stainless borlas under my nova. 350/350 combo with x pipe. Looks awesome, sounds great. They are quiet for regular driving and get louder when you get on it. I love them. Expensive but worth it to me.

When I get there I am hoping for a low rumble at idle...then when I get on it, heads will turn

I am a ways from that though, but I like to gather the information of this thread, good to know for when I am ready.

Added: magwakeenercew2jh, I like the sound of those on your vid, and that classic Cali plate is sweet!!!

LilD · 02-10-2011, 10:18 AM

I have Flowmaster 40s with 3 1/2" pipes and turn downs a couple feet ahead of the axle. I love it.

Im sure the neighbors dont at 5:30am when I start it to warm up to go to work though

BOZO · 02-10-2011, 03:31 PM

If your system ends up being a little louder than you care to listen to, another option is to put inserts in your headers. These can be bought through Jeg's, Summit, and other vendors. Just drop the pipes at the headers,insert the pieces and bolt it back together. When run with loud mufflers they do a lot to eliminate the resonating pulses at lower rpm.

Relish · 02-10-2011, 03:48 PM

i got 2-1/2inch dual exhaust with 12inch long cherry bomb glasspacks and it sound sweet but i'm sure the neighbors hate it.

Magnaflow will do just that, you won't be sorry

19seventeeCustom · 02-09-2011, 11:07 AM

I run Full length headers, into a 3" Y pipe into a single 2 chamber flow turneddown just before the axle, has a nice little grunt and not loud. Even though loud is subjective.

A lot quiter than my LS1 w/cam an long tubes and no muffler

big_al_71 · 02-09-2011, 01:28 PM

Doug thorley headers, with dual exhaust no X pipe going into Dynomax mufflers out the back under the rear bumper. Not too bad definetly quiter than flowmasters..

Sounds louder than my FM-70's.

Hooker long tubes with $16 Cherry Bombs. They are the radio! Period correct too!

$19.99/ea thrush

can't beat the price.
and i have to say flowmasters or dynomax is the way to go for what you're looking for.

Stano · 02-10-2011, 12:40 AM

I love flowmaster 40s. Have them on both my trucks. However if I wanted to go quiet at idle and party with the pedal down I would choose ss borlas. I put them on my bosses hemicuda I built and it sounds sweet. You may have heard it on the season three bullrun show. Alot of people liked the way it sounded. They look good and sound good what more could you want. lol

This is my set up on my truck loved the sound for a while. But take a long road trip and I start thinking I need to do something about it.

Jacfourteen · 02-10-2011, 04:16 PM

I have longtube headers, true dual, and 2.5" flowmaster 40s. The mufflers are mounted under the front of the bed and are dumped (no tailpipes or turndown). I think it sounds good, but from what you want I don't think it would be for you because of the raspy sound. If you want smooth sound I would suggest magnaflow or something similar. I have a magnaflow on my 01 tahoe and it is deep and relatively quiet at cruise, then you get on it and it really livens up.

Heres clip of my 68 with Flowmasters, the rev is to about 4000 RPM (sorry you can't see anything it was raining so I set the camera under the bed).

And here is a clip of my tahoe, I know it has a different engine and catalytic converter so it doesn't sound the same, but you can get a feel for what magnaflows sound like.

I'm not sure why I can't get the player to show up on the screen, but I guess the image takes you to the clips.....sorry

bfay17 · 02-10-2011, 06:53 PM

Im running thrush welded on my 71 and my 88 and really like the sound of those. I put a set of glass packs behind the 454 in my 70 4x4 with true dual 3 inch and its way louder than even I like and im 19! My buddy said he could hear me well over a mile away.

1968CHEVYC10 · 02-14-2011, 03:11 AM

Here's my '68, gotta stock '75 350, with LMC's dual glasspacks kit.

Love my hooker aerochambers but only with turndowns

jhwkns · 02-15-2011, 12:55 AM

I had my exhaust re-done last summer. I told the guy I wanted the biggest quietest mufflers I could get, and to run the pipes all the way to the bumper. After twelve years I was tired of the sound of the flotech turbos. It's Cadillac quiet now. Literally. My rumble used to set off alarms. Now they don't hear me coming.

Nice, I sometimes think about doing that to my burb.
I personally like to hear my motor, than to hear an obnoxious exhaust system on an otherwise mostly stock motor.

jakeblues652 · 02-15-2011, 04:33 PM

oh, i forgot to mention, dont forget to get one with a good muffler bearing. those things are a dog to replace

crazy longhorn · 02-15-2011, 08:06 PM

I was a big fan of the Dyno Max Superturbos for yrs....a good flowing muffler, that ran mellow@ idle & low revs .....till you stepped on the loud peddle! Last trip, I wanted something more aggressive, & tryed a set of 40's flows. I could not get with the drone in the cab & the tailpipes exited under the back bumper! I tryed a set of 50's Flows, & I like em....nice rumble down low,no drone on the hyway.....& they are about as beligerent as the 40's when I stand on that loud peddle (I am a mid 50's teenager
