Im pretty sure im going to be getting a flowmaster 40 series muffler si/do. Im wondering what sounds better on a 3.0, an original 40, super 40, or delta flow? Also, for all you guys that have this exhaust, did you buy it as a kit, or buy the parts separately?

 

On these trucks......they all pretty much sound the same. It's when you add two cylinders and a carburater is when they start changing sounds. MOST folks run a Delta Flow 40, as that's whats usually avaliable....I've ran a super40 and currently running an original 40....and the original 40 is slightly louder than the super 40. The delta flows, are quieter than the originals. One thing about the delta flow 40s, they have ALOT more avaliable in/out/size combos.....2.25 in, dual 2 out. that sorta thing. One duals you can get in the super 40 is the 3 in/2.5 out.

Hoped i helped a little.....i know you have a 3.0, but just tryin' to help.

 

Thanks, yea it helped a lot. What do you think would be a good size for piping. 2.5?

 

Also, did you buy your exhaust as a kit, or buy the parts separately?

 

i got the orginal 40 3in in and 2.5 out and its loud and i love it...you have to buy the muffler then get a muffler shop to run the pipe...i love my flow makes my 4 banger sound like a mustang

 

Yea Im pretty sure im going to get the flowmaster original 40. I just have to decide on what size piping im going to run.

 

I have an Original 40 dumped before the rear axle. SI/DO 3'' in 2.5'' out and it's loud as hell. I love it.

 

I got the original 40 si/si dumped before the rear axle. I love the way it sounds. 2.5" in and out.

 

Yea its a hard decision. Im leaning towards 2.5 in, 2.5 out.

 

You really don't need 2.5 in/2.5 out......on my brother's truck, fx4wannabe, he's got 2.5 all th way, and he wishes he got 2.25 all the way. And he's a got a 4.0.

 

Dangers exactly right, for the 3.0 you will be fine with 2.25 and 2 out, but I think its even better if you get it sized down to 1.75, then you can put whatever size tips on there and won't lose a lot of backpressure. I'm no expert tho so I could be wrong.

 

Ok so the 2.5 piping sounds worse than the 2.25? I guess i will downsize it then. Would 2.25 all around sound good?

 

Thing is.....for what power we put out in our trucks, combined with displacement.....you really don't need 2.5. Heck, my 450hp 406ci chevy uses dual 2.5s. As my brother said above, I wish i went with 2.25 on mine. Lost some power w/ 2.5. The muffler...that's really no biggie what the sizes are, the shop can enlarge or use those transitions things to change the size. Like the Super 40 is only avaliable in 3 in/2.5 dual out.

I wouldn't say 2.5 sounds worse, just performs worse...and you honestly don't need pipe that big.

4.0 calls for 2.5 in/dual 2 out.....i'd do 2.25 in/dual 1.75 or 2 out for a 3.0L.

 

So if I get 2' piping compared to the 2.25, will I lose any sound?

 

has anyone tried the new Flowmaster 44 series?

 

Yeah, my current is a 2.25 dual out right now.. works perfect, nice and aggressive when you romp on it without it sounding muffled... nice bark to the engine =)

Soon as I get my JBA headers and my other stuff installed over the next 2 days.. I'll make a video.. comparing my stock truck with just the exhaust.. compared to me now with a CAI and headers

 

A Flowmaster Super 44 is the same as a Super 40, but in a smaller case.....more compact. 4x8 vs 5x10 cases. I had a Super 40 and loved it. I'm trying out an original 40. Both mufflers were used in different exhaust setups...so that changes it as well. On my 406ci chevy, the super 40 is pretty mellow at idle and cruising...then when you romp on it, its MEAN! The Original 40 on the same truck, is loud and beefy at idle, and when you romp on it, it's mean, even more meaner than the super 40. Hope i helped.

 

helped me understand a but more about the differant setups, but now i dont know if i want a original 40, super 40 or 44

 

Big, Bigger, and Biggest.. from Origional to Super to 44... what do you want? We cant really describe it unless you tell us what your looking for...

 

Ive ran so many different mufflers just for 2 reasons......1. "I wonder what this sounds like on my truck". And 2. IT's cheap to swap mufflers. Okay....maybe not "cheap" but it's relatively cheap to swap out. $65 here, 5 months later $50 for a new one, 6 months later.....

I've had stock, Dynomax Ultra Flow Oval, Magnaflow, Cherry Bomb Glasspack, Flowmaster Super 40, and currently Flowmaster Original 40.

Pretty much, any Flowmaster 40 series all pretty much sound the same. Original 40 doesn't have the delta flow technology, and from my experience and alot of other peoples experieces, the delta flow makes it a little quieter. But it's got better flow than the Original. And the Deltas are better in the interior resonance department.

 

I'm looking for something with a deep tone that sounds healthy but really i dont want something that dies away at higher RPM's

 

ive got the oricinal 40 series with 2.25 out duals sound mean at idle but the higher the rpms the more ricey it sounds especially for a 3.0

 

I like the sound of the super 40 personally, but it's to loud for me on my truck. I like my Borla.

 

How is the cab noise noise with the original 40?
