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

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

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.
