i bought my truck with straight pipes. it was obviously done by a professional shop because its new piping from where the cats were all the way back. new hangers and everything.. i love the sound myself, but it is REALLY loud. Is this setup hurting my performance or the motor itself? if so, what is an exhaust with the most sound and performance for my truck? 06 FX4

 

straights make you lose tq man..and as far as hurting the motor..if its still got cats i dont think it hurts it...i kno that without cats you will burn up valves...but i dont think straights hurt the motor

 

Does it have any type of crossover?

If not, adding one will definately help with the loss of low end power.

 

mudterrain, ive been meanin to ask..is that a ranger or a f150 in that picture

 

if done properly you wont lose anything. i think it is openclass who has duals and gained power. maybe he will chime in but i think his is 2 1/4 inch pipe with a crossover.

 

park a ranger underneath my beast and then you WONT mistake it for any little mini truck.. are you hating or is this a serious question?

 

ok. my bad, just made myself look like a dumb ***. ha. you were talking about the other truck. sorry man!

 

naw its serious..those headlights look like a rangers...and that little bullguard or whatever its called isnt helpin much

 

definately F150 headlights.. i would like to see a few diferent pics of that truck

 

Nope, just make it super loud.

Na thats a F150 body. Grill and headlamps same as mine are

 

yea i see it now...since the bumpers off it kinda threw me off lol i do appologize lol

 

im kinda diggin the bumper.. i would def choose thicker piping tho..

 

If you dont want your OEM front bumper I'm sure my truck would like it! I envy all the '06+ owners with that sweet round fog bumper.

 

another thing that has been happening in the past 2 weeks or so.. when i floor the truck off the line, or on the go, and it downshifts to 1st or 2nd gear (depending on the speed im going), it pulls hard till i hit the upper RPM's (not redlining tho) and then it acts like i just hit the governed speed of 100 and the exhaust starts popping and sputtering. but when i ease off the throttle a bit, it pulls hard again and the exhaust mellows and smooths out until it pops back into the next gear. then all back to normal... whats going on with that?

 

Sounds normal. You do have a bit of lost torque with straights so it will pop like crazy and climb the speedo slowly. The OEM tune shifts it the way its supposed to, the straights dont always wanna agree with it though. But flooring it its natural to downshift because it gets a better grip on the gears, that way it wont stall and it will move quicker.
