hey yall i just joined here tonight and dont know how this all works. hopefully someone can help me out. my truck is a silver 2001 supercrew 4x2 and i have a custom H pipe, true dual flowmaster 1 chamber mufflers, and pipes comin straight out the back. ive been thinkin about gettin my tips relocated to before the rear wheels on each side. that being one pipe on each side of the truck at about 45 degrees angle or less. similar to a lighting but on both sides and with one tip each side. has anyone seen this setup? i cant find a picture online of it anywhere. thanks

 

You cant do it to the drivers side because the fuel tank is in the way, and its un-safe to route it below the tank.

 

Yeah, you won't be able to do that.

 

yea i had a feelin the gas tank would be a problem, although i did actually see this exact setup on one and only one supercab f150. i just saw it drivin down the road and didnt get a chance to look under it. so heres another question.... my truck has 4 cats. i wanna get rid of the rear 2. can that be done with my truck bein able to pass inspection?

 

ditch the front cats and replace the rears with high flows

 

Go with the highflow cats from Magnaflow

 

andy-jr ive heard ur truck on youtube and its nice. but honestly, how much of a difference would i notice if i replaced the rear 2 with magnaflow high flows? and what type of difference would it be... im sure glad i joined cuz this is all so helpfull haha

 

First, let me say welcome. If you replace the cats with Highflow cats then you will notice the sound will be two or three times louder then what it currently is. When you do the highflows you replace all four cats not just the rear two. Performance part you will not notice much of a differance except maybe in the upper rpm's. Hope this helps.

 

thanks for the welcome... that would be awesome if it could be that much louder than it is now bc it is very loud right now. so on your truck in the youtube video, you have 4 high flow cats? if you dont mind me askin, how much did that cost you with installation? i dont exactly have alotta money im a senoir in highschool and dont have time for a job--->too busy with baseball

 

You take out the four stock cats and replace them with two highflow cats. It's been a while since I had it done so I'm not sure of the cost. If I had to guess I would say 350 for everything(parts & labor)

 

ohhh gotcha. am i gonna be able to pass inspection with that?

 

If you remove your rear converters you may get a CEL. The front ones you wont. Hi-flow replacement converters you'll be fine.

 

ok well heres the problem with that...no exhaust shop will take them out bc its illegal....and i deffinitely cant do it myself.....

 

What state do you live in?

Either find another shop, or obey the law and dont risk a cat converter modification fine.

 

North Carolina.
