from what i heard ...common bolt ons like intake exhaust and headers does not void warranty...there is a website link posted on one of the topics that have the whole warranty issue...but definately talk to your dealer...he might give you the go...or maybe not dicussing the warranty.
Hey guys. This is my first post, hopefully i'm doing this right. I installed headers on my 95 civic and the only problem i had was taking the O2 sensor off of the original headers due to it being on for so long. The 6's shouldn't be too different. Just a bolt on. Also, any performance shop should give you an install quote as well as tell you if it will void the warranty.
