Is this possible???? I just installed a set of Pacestters and a ORY. It feels like my car hits the rev limiter now. Can changing the headers cause something like that?

You say it " Feels like it hits the rev limiter " ?? Unless you had your car tuned after the install and the rev limiter was changed it should be the same. It might be banging or rattling under the car. More info would help.

I have changed the rev limiter with HPP3 but way before the header install. The car pauses between shift just a little now. My car has ALWAYS shifted fast and clean. I have a torque converter and a shift kit. If you listen to my car shift it sounds like someone changing gears in a manual. The only thing that has changed is the headers and y-pipe.
ive actually bumped the rev limiter on the 2-3 shift 3 times now since my header install 3 weeks ago and never once hit it without the headers so id say yes it is possible...kinda like when people go to different gearing and the computer cant compensate for the eccessive acceleration and taps the limiter...im just gonna bump the limiter up once i get my heads/cam on and probably keep the shift points around the same...give or take a few hundred rpm.

LT headers changed my rpm band. Hit the rev limiter several times before i realize it
Mycar felt like it was still pulling into the 6es. I usally shifted out around 55-56 before.
I need to get to a dyno and see whats up. I did the slp LT y-pipe hi flow cats and loundmouth all at the sametime
