how do you install this properly .how far do u screw it in i need it at a certain angel to clear everything.this is the universal one

 

why exactly are you using this?

 

i put a header on my 04 dx and with no cat i now throw a emission cell light

 

you need to install a cat then

 

no this tricks the computer to think i have a cat

 

i know what it does...
it's illegal, immoral, and hazardous

without a cat, instead of NOx, CO2, and H2O, your exhaust will spew out deadly carbon monoxide gas. that's why it's illegal.

you really should just get a universal magnaflow cat (~$60) and have it welded into the exhaust, right after the header, by an exhaust shop. You'll also need an O2 sensor bung (~$1-2), and an O2 extension wire harness (~$20).

 

dito...... ditch the sims is the 1HP worth the risk of geting a heavy fine for removing the cat..... i dont think so!

 

well ialso have header back exhaust with a hiflo cat built in

 

you sure you're not talking about the resonator?
or a so called ebay "high flow cat" that's actually a test pipe?

what exhaust is it?

 

if its a real cat then it should have the cat in the same location as stock.... if not its just a resonator and then the muffler after that.
