Demon, where would you put the stock manifolds WITHOUT gutted pre-cats?



The threads I've read on the subject and my own experience with gutted manifolds indicate that there is no measurable gain from gutting precats as the enlarged chamber & subsequent piping slow the exhaust flow to ruin exhaust scavenging. So, precats are not really a big restriction compared to gutting. The stock manifolds just SUCK. Headers will net you between 5 and 15% HP increase at the wheels & very noticable torque gain.

Dammit! Now I have to go order some MSDS headers!


Must be that jumbly-wumbly thing happening again.
