hey, im pretty new to this, but i love the j-body's. I own a 98 2.4L sunfire. im starting to work on the performance aspect of it now. I got a weapon r dragon intake, obx racing headers, and the dual cat back system from rk sport. I am just wondering if anyone has a good ideas for a cat setup. i think id like the high flow cat with the O2 simulators from rk sport, but i cant seem to find much for numbers on what it adds. Basically just wondering what people have found that works best.thanx

carsound cat made by magnaflow. you can get one from Gravantuning.com
and if installed right, no need for 02 sims



Im a Xbox 360 fanboy...and damn proud of it!!

hmmm, how much does an o2 simulator cost???


if it ain't broke...MAKE IT GO FASTER

yeah the sims are only like $200 cdn., so i mean it not a big deal to buy em.cool thanx
