does removing the catalytic converter add HP? Options

[nate95]

Hey i was just wondering if i were to remove the catalytic converter if it would add any horse power? or what about getting a "Y" pipe before the cat. so i can still have the cat. but have it go straight out when i want to race?

so if i do my exhaust... i should remove my primary and keep my secondary? would my car still be legal if i keep at least one of my cats on there?

since you live in Cali the emission tests are pretty tough out there so removing your primary would probably make you fail. You might pass if you remove your secondary cat, but I don't know.

IMO If you get an exhaust done, get your car inspected right before, so your sticker would be good for a year and when it is ready to get inspected again, put your old system back on. Then just swap again after.

tell me about it... my car would have so much more potential if cali laws weren't so anal. plus it requires a lot of money. but other than that, the gains of an exhaust aren't worth the hassle and what-not. the only real reason i want a new exhaust is for the sound. but then again, that might be a lil ricey on my slow car.
