So I'm under the car replacing my stock hpipe/cats with an off road hpipe and I see that when the previous owner rebuilt the engine he just plugged the tube. Can I just delete the tube and close it off at the hpipe? I see is has this filter thing at the end do I need that? Sent from my HD1905 using Tapatalk
Thats actually a check valve. You could remove the crossover and install air delete bolts in the back of the heads. You don’t need to run any of that air pump stuff. Sent from my iPhone using Tapatalk
If it's been running like this I'm sure they already installed the bolts in the back of the heads right? What's the purpose of the check valve? Sent from my HD1905 using Tapatalk
Do you have emissions tests That would be the only down fall I did a complete delete on mine But I have no emissions tests
