Looking for Headers..help w my application
Im not exactly looking to blow a whole lot of money so I am looking at some Pacesetters. My question(s) is will I have trouble with clearance with LTs? What type of Y-pipe will I need? Should I splurge and get coated or are the black finish fine? Any and all input will be greatly appreciated.
The only difference as you stated yourself, is the cat. If your state doesnt have checks, then yeah, you can get away with it
Some states don't test emissions they either use a OBD connection to see if the cars PCM says all the emissions stuff is working (as if it is then it will be fine as type approval means all new cars meet emissions). Tuning can get around this.
Sometimes there is a visual inspection also, so they get under the car and look and see if cats are present. Some people use cat casings hollowed out or something similar.
Sniffer test, this is a sensor placed in the exhaust pipe and measures the content of the exhaust gases. There is no way around this.
Some states are pretty lax in testing for emissions, but law CAN and DO and WILL change. So what is ok today may not be ok this time next year.
IMO you might as well run CATS. Yes they may slightly affect HP but if you get some good hi-flow CATS then the loss will be minimal. Random Technology even make metal matrix CATS which will not pose a restrction even on 500+bhp motors, but they are a little pricey.
The choice is yours. But if you do run an ORY don't be to suprised to eventually get caught and fined, because it will always be a possibility.
As for me, well in the UK there really is no option on cars newer than 1993, they MUST have CATS, so I'll be going for the TSP Catted Y pipe to begin with.
