Hello all
I'm looking at doing a complete 2 1/2" exhaust on my ecotec, including extractors...all in stainless...so this is my question: living in Adelaide, we don't have roadworthy inspections. So, honestly, has anyone or does anyone have the shell of a catalyctic converter with just a 2 1/2 inch pipe running straight through it (no mesh, just a fake shell)? Highly illegal I know, but just wondering...does it do any harm to the engine management side of things, and does it drop back pressure too much?
Some serious input please guys...I know this is cheeky but I have this on a VN once and it went much harder. Ecotec though...I have no idea.
The car has a cold air intake only at the moment, and no forced induction...just curious do I really need the cat????
Any thoughts? Cheers guys :thumbsup:
