Re: Loud air sucking noise on acceleration

I hope so!

I also picked up a header pipe, so eventually, hoping to take it to a muffler shop and have a complete exhaust installed. This pipe i picked up is 2-1/2”... the one I have on the truck is 2”. Not sure if I will see a difference in performance when I get the 2-1/2” exhaust installed. Then again, I’ve been thinking about getting some 292 312 exhaust headers, like the two piece ones on the Langdon website.
