upon looking for an exaust system for my truck i of course ran across the ever popular flowmaster. can anyone who would know explain the difference between the different series (40, 50, 70, etc.) and the difference between regular and delta-flow.

and does anyone have a website link or somewhere i can get info on the UPD intake. it sounds like the best bang for the buck as far as intakes go.

www.ultimatepd.com for the intake
as for flows the 40 is louder - 2 chamber
the others i dont know summit or jegs usually tells the diff

 

the 40 series is a 2 chamber
the 50 series is a 3 chamber
not sure what the 70 series is

the delta flow is supposed to produce more horsepower than the regular flowmasters. the delta flow 40 series isn't as loud as the the regular 40 series. i think that you pay about 20 dollars more for the delta flow.

They have sound clips of their mufflers on various vehicles.

if you order from the UPD website type in "group purchase" in the comments section, they are going for $179. I got mine for 159 because I already had the K&N filter..
