Need some help

[mscally07]

Well, i have a 2005 gtp and am looking into buying TOG headers. I dont want to replace my stock Cat. since i replaced it 300 miles ago ;-/ and have the stock exhaust still. I need to know if the TOG headers will bolt on w/ no problems and if the O2 sencer will not cause any check engine lights to come on. If i get it done at a local Mr.Muffler, would there be no problems with the computer? Please help. Thanks.

TOG's require a specific downpipe, Hope you didn't pay for the new Cat, cause federal law warranties them for like 7 years

You'd have to get some custom welding done, and the size of the openings on the stock cat may be a restriction.

Yeah the dealer i bought the car from was all about getting it off the floor and selling it and didn't tell me about the check engine light coming on. I got half way home form the dealer and the check engine light pops up. The cat went, and they tried getting me to pay for it. But we called GM and they called the dealer and yelled at them saying its covered under warranty. But yea, im looking to free up some exhaust flow so i can upgrade my pulley size to a 3.4. What do you guys think, down pipe, or headers.
