good brands and pricing for high flow cats?
What are some good brands and their prices for high flow cats? I did some quick searching and only found magna flow to be popular but I'm pretty sure there are other good ones out there. Do aftermarket cats also have backfire as well? thanks!

After having no cats on the Wife's IS300 for the first 5 years, we put it back on once smog time came and the bottom end torque was notably better. Never removed them after that. I'd value torque at the bottom end more so than HP at the top end myself.
