Description:	The most aggressive-sounding street and strip muffler in the Flowmaster product line. The 40 Series Delta Flow generates a powerful, aggressive sound outside the vehicle with minimal interior resonance. with increased horsepower, torque and fuel economy. If you are looking for the traditional "Flowmaster sound," the 40 Series Delta Flow offers more of it than any other muffler.

Pros:	more torque
Cons:	not loud enough

Installed on 93 F150 5.0L. Wanted a more manly sounding truck. Some noticable increase in engine performance.

Not loud enough due to the fact that, by nature, the catalytic converter cuts down on engine noise b4 it gets to tail end exhaust.

Has a good hollow sound though.

Pros:	Deep Tone, Not Overpowering
Cons:	none.

Third Vehicle with one of these. You can never go wrong. Not too loud at highway speeds to drive you friggin' nuts. Sounds great at startup and idle. City driving is throaty enough to set you apart from the rest. Just a hint, Buy the cat-back DOR on Ebay for $125.00. Same components, same results.

Pros:	Better sound
Cons:	no performance of mpg gains

Switched from stock muffler to 40 series, a little bit better sound, but not much, no performance of mpg gains. Upgraded to Super 40. MUCH better sound, and no not obnocious. Very slight increase in performance, no mpg gains.
