What the difference between the orignal 40 's and the super 40's. I heard the orignal sound better. less drone,less ricer sound. Is this true, also I can get 2 chamber orignal flowmasters. Whats the difference between delta flow. I also heard delta flow makes the mufflers sound bad. Everyone tells me to get the orignal 40's because they sound the best.

delta helps out with interior resonance. only major design with it. why not just get the american thunder setup

pretty sure delta flows are more compact if u have clearance issues? super 40s are the newest they r the black ones which make most hp and small interior noise, and sound the best which is why i ordered them the other day. they have a very unique sound to them and do NOT sound ricer....

wasnt their a rumor going around they were the same muffler on the inside?

Quik

delta is for interior noise. nothing else no they arent smaller and the newest flowmaster out is a hushpower

i didnt mean newest flowmaster... i meant out of the 3 he named obviously.. and r u sure, on tv today on trucks it showed a 40 series and a 40 series delta flow and it was half the size saying its for tight fits.... [&:]

it had the delta design doenst mean it was the delta muffler. trust me my truck has the delta, my z24 has the delta and my stang has non deltas. stang is louder in and out of the ride cause of it. sounds are close but i have different series. in the end the sound is the same but on different levels

dc_mann8

ever think it might be louder in your car because of the mustang vs a z24....


Significantly Outflows The Older 2 Chamber Mufflers...

for even more horsepower and torque. The Super 40 Series gives you less interior sound, while still giving your vehicle a deeper exterior sound. The new patented, 5' x 10' x 13' , 19' long black case design is modeled after Flowmaster's Race Muffler. The Super 40 far exceeds older models on Dyno Tests. The sound of the patented Super 40 makes everybody stand up and take notice! So get that beautiful hot rod sound along with increased horsepower and gas mileage!


thats copied off of flowmaster site so there u go for the guy who was asking about them.

I have a set of 40 series I used for three months if you want them. They are already broke in so they will sound great right after install. LOL They are in almost new condition. Name your price.

Ok i just got some info, the delta flows are quieter than the original, the originals are the best beastly,monsterly muffler you can get from flowmaster.
