Im planning on getting a SI/DO Maganflow muffler soon, or would just running a straight pipe be better? $45.00(straight pipe) vs $225.00 (Magbaflow fabbed by muffler shop) Anyone with a 5.4 w/cats have a straight pipe setup?

 

You like having to pay money to get the ehxaust all re done when its time for SMOG? Yes I live in Orange County, CA to .

 

I also am running no mufflers on my truck it sounds great to me also some people would not like the loudness but a truck should be loud and mean lol. I am running duals and summit shorty headers (pacesetters)

 

Love my straights....I had a magnablow and hated it....Straight pipes is the only way to go on these trucks.

 

I have true dual straight pipes (no crossover) and absolutely love the loud sound!

 

I have 2.25 inch true straights with a small H and stock cats built in... I love it...its really quiet on idle but when you crack on it... or pass another vehicle.. or... i just love it!

 

here is how i have my setup and i have done this on my friends truck too, these pics are of his truck only a few days old

remove muffler, by unclamping it not just cutting it off


cut off the last 2 straight pieces with the 1 bend


then cut it down to fit and weld a 24x3" tip and a hanger or two


finished product may cause people to fall over backward because of how much they love it


then a vid

azmidget91 that thing does sound pretty damn good..

 

I have a 98 f150 4.6L with a bottle muffler and a 4 inch tip i wanted to stright pipe it but i was told u have to get it retuned did u have to do that?

 

total bull****

 

yea thats bull, my truck runs just as good without the muffler if not better. I think i even get better gas mileage (but that could just be in my head. but no you deffenetly dont have to retune.

 

Yep i totally agree and i am gettin better mpg with my straights then i had with my maggy.....
