Originally posted by specvracer Why do all the headers for Spec V say intended for off road use only? So if we install them do they affect emmisions that bad?
All headers remove the first cat in the emmisions system and some remove both(stillen). You shoul still be able to pass a emmisions test with one cat.
Originally posted by specvracer I hear that AEBS is comming out with a header with highflow cat. will that mean it would be safer emmisions wise and Do headers void waranty?
in general high flow cats can polute more. Headers can void your warrenty but they really can not make any part of your car go bad except for the o2 sensor. The o2 sensors are part of the emmisions system which the header can void, but its really up to the dealer
Federal law prohibits a dealer from voiding your warranty just because you are using aftermarket speed equipment, with only two exceptions: the warranty can be voided if the aftermarket part causes damage or adversely affects the emissions or the emissions system. In recent documents produced by the SEMA (Specialty Equipment Market Association), a trade association-representing specialty automotive parts manufacturers, and the following quotes have been extracted:
"The vehicle manufacturer is not allowed to void the vehicle warranty just because aftermarket equipment is installed on the vehicle. This protection for consumers is the result of a parts self-certification program developed by the Environmental Protection Agency (EPA) and the Specialty Equipment Market Association (SEMA).
"Under the program, if a parts maker completes the EPA process of self-certifying its parts, the vehicle manufacturer cannot void the warranty even if the certified part has failed and is directly responsible for the warranty claim. In cases where such a failed aftermarket part is responsible for a warranty claim, the manufacturer must arrange a settlement with the part manufacturer, but the new vehicle warrant is not void under the law.
"If the failure to honor a claim involves the new-vehicle warranty, and it appears that the manufacturer is improperly denying a claim, the incident should be reported to the Federal Trade Commission (FTC). The FTC is responsible for monitoring compliance with the warranty law; the agency's telephone number is 202/326-3128
