that my exhaust is slowing me down!!!!! back almost a year ago that i was a stupid kid and figured that bigger is better right? NOT! so here is my issue i have a 3INCH flowmaster 40 sieries cut the flange off of the last cat welded the exhaust stright to the cat and then its fully welded all togeather so here is my question is there any way i can figure out how to fix this with out buying a new cat and cat back.....? cause i dunno if i wanna spend that much but u pay for u mistakes right

 

if you have 3" piping, only way of fixing it, is replacing it... Thats WAY to big for your truck..

 

ya i know but how can i go about replacing it and 2.25 is good right

 

2.25 or 2.5 will be fine with SI/SO

2.25 is good for duals.

 

i have 2.25 and it sounds really good and i didnt lose anything when it was installed

 

from the last cat to the muffler i got it put 3" then from the muffler to tip its 2.5" with a 3" tip and i didnt lose any performance when it wsa installed its just loader then everyone elses.

 

well im running that set up a K&N ram air and a bama chip for mileage and im still going threw a 1/4 tank a day and also the fact that when i run the 97 prog i dont feel anything and its kinda scaring me cause everyone is saying WOW i feel the differance and im not

 

Maybe you can add 2ft of smaller pipe after the muffler to gain back a little backpressure . Shouldn't cost too much $. Just so we'll , know what kind of milage are you actually getting ? Divide gallons by miles . I checked mine yesterday and averaged 26.5 which included some 70 to 90 mph driving and about an hour of stop and go . E-fan and pulley really help!

 

YOU AVERAGED 26.5!!!!.... uis it electric??.. cause im geting like half that lol

 

same here man!!! i get like 16 if i'm LUCKY...and i'm on the hwy a lot. but i do mash the gas a ton

 

wow i get about 19 city and 26 hwy... always have too but i do drive like an old man

 

When I first got the truck , I could only get about 23.5 mpg ; and that was driving like an old man . To get that I had to keep the rpms in the 2300 range. With 4.10 gears , that means slow . E-fan added about 1.5 miles per gallon. The pulley after that added about another 1.5 mpg. And both mods add to the usable power. I do a lot of hwy driving, so I put on 32's to bring the gear ratio from 4.10 to about 370. Automatic transmissions use a lot of power just to force oil through the system [ some like fords c6 use over 60 hp] , so I drive a manual. I couldn't believe how much the damn clutch fan weighed. Do yourself a favor and ditch the damn clutch fan soon. As you already know . 3.0's don't have any power to waste. bob

 

i thinking i might by the e-fan and an underdrive pulley and if nothing helps then im switchin it out
