Aftermarket downpipe worth it?
 

Just wondering if they are worth it on a truck with intake/exhaust/tuner or not really?

Re: Aftermarket downpipe worth it?
 

I noticed it on mine when I did it. I say its a must on every obs

What did you notice? Increased turbo/exhaust sound? Faster spooling? Earlier spooling? Holds boost better?

you guys have the crushed downpipes right? mine came off a bus and isn't crushed like the truck pipes i've seen

According to the guy in my other thread ya they are crushed. So your school bus DP is 3"? Where do I go about finding a school DP for cheap???

bus garage? lol and its off a 7.3 short bus. a junkyard if you can find one

So if I pick up a down pipe, you gonna help me beat out the firewall so we can install it? ;)

you shouldn't need to with a 3"

From what I gather on here, ANY aftermarket DP will need the firewall beat in to make it fit?

3" downpipe may only require the cab seam to be bent down.
