Wow this place is getting worse the h/t.
Anyone that doesn’t install something themselves is an idiot.
if you don’t have a DOHC you’re stupid.
and if your car doesnt look JDM (just like everyone else) its ugly.
Anyway...
I have to say that it is an easy install and it would have been much cheaper to do it yourself.
as for the cat, I have run my SOHC with header and test pipe (replaces cat) for a while and have switched back. While I had the test pipe in I had better power at high revs but it sacrifices low end torque, I personally decided that I would rather have torque on my little Honda that has none anyway then a higher top end.
It’s good to see your still working on your car, just remember when it comes to your car, it’s only your opinion that matters.
