Does anyone know If i can put a ragazzon straight pipe on while keeping the cat for emission reasons?

 

If I'm understanding your question correctly, as long as you don't touch the downpipe (where the cat is), you should be able to use a straight pipe and pass emissions no problem. The JCW only has the one CAT at the downpipe and a silencer on the midpipe and then the muffler. You would effectively only be changing the sound and maybe a smidge of HP, but nothing emissions wise.

 

Awesome! Great. Thank u for your response.
