Damn dynomax super turbos and glow masters will drone.
2 1/2 Summit low buck turbos. Got the old turbo sound. No drone on mine.
I don't like the Flowmasters because they make everything sound like a Mustang. Lol
I found a huge difference in the way my exhaust sounded from my cam change. I knew I went from completely nuts to Wild. So to say what one would sound like with the 340 doesn't even make sense to me. With which cam? With headers or stock manifolds? Stroked or not stroked? X pipe? T pipe? All the way out the back? Out the side? Location of mufflers? I think there's room here for all kinds of different sounds...
Borla ProXS 40659 or 40658 fit in the stock location and sound pretty bad-ass. Don't balk at the price... these are 100% stainless steel, and as they say "you get what you pay for". I have em on my 340 with shorty headers, H-pipe, and 2.5" pipes. Fantastic. Borla® ProXS™ Muffler - Center / Offset | Borla Exhaust
I had Dynomax Super Turbo 2 1/2 with H pipe on the 340 Valiant, they had a drone. The Flowmaster 50 Deltaflow have a nice rumble on the Barracuda, no drone. On the freeway the Barracuda had no exhaust sound, we love that for 200 mls rides!
I am Happy with my dynomax vt with a cross pipe on my 340.
Dynomax VT R.I.P. I too loved the sound and the concept of having the best of both worlds, but it's been a while now since they discontinued the VT. My guess is that anytime there's mechanically moving parts inside a muffler there's going to be warranty issues at some point...
The Jones Max Flow mufflers seem pretty well liked and they're relatively cheap. They sound weird on my combo for whatever reason but the build quality looks good for the price and the flow-through design is pretty hard to argue with.
So I am going to give you three different examples of Flowmasters. I have a Maxwedge with Flowmaster 40's that sounds open with the dumps closed that sounds wicked... It does have a cam to back it up. It does drone slightly at certain RPM. My friend has a L78 with stock exhaust manifolds and pipes... With 40's sounds rediculus! At a car cruise I saw a C 3 with a a stock engine, manifold and exhaust with Flowmaster 40's that sounded very healthy. So I just installed an Accurate Exhaust with stock manifolds and 40's on a 340... can't wait to start it. It may not be the muffler of choice for racing but if you want to feel like you are driving a hotrod, value for pleasure can't be beat. Flowmaster haters can knock it all they want, but no other muffler makes you feel like you are riding a Harley in a car!
That unique Flowmaster sound is what makes that company profitable and has made them a household name. The bass notes that are typically lost on a Turbo or straight through muffler with glass packing has given them that signature sound. I can tell a FM muffler blindfolded. The downside of the 40 series is it’s loud and they typically drone like crazy. FM has done a nice job in quieting things down and greatly reducing drone with their 50, 60, and 70 series while keeping that bass, FM sound. People don’t realize that and tend to use the “ dronemaster” description for all FM mufflers. Do they flow like a good turbo or straight- thru? No. But they flow enough for the street, where you spend 99.9% of the time.
Kooks polished stainless mufflers. Love them
I like my flowmaster hushpower pro's but they aren't necessarily quiet!! The 3" are kinda big cans to tuck up in there also
Yes i had a set of turbo mufflers on my 68 s 340 start out mellow but sound better as you go but don't get to loud
Flowmaster Deltas. Crispy, throaty love em’
I run Black Widow Venom 250's on my 340 Dart Sport
I recently switched from flowmaster super 40s to magnaflow pn 11229 and all I can say is wow. The car sounds 100x better. They were $100 a piece but well worth it in my opinion
AP Xlerator is a decent option: AP Exhaust Xlerator Performance Mufflers or the AP turbo muffler Big Max for a quieter option AP Exhaust Big Max Turbo Mufflers
They’re currently dumped in front of the rear axle with turn downs so it’s tough to say. I have an appointment at the exhaust shop next week to have my cutouts and tailpipes installed
Summit 2 chambers. $29.00 Each 418 Stroker,3" exhaust.
