I am planning on purchasing Cattman y and b pipes in the near future. I have a few questions about Random Tech catalytic converter. First, did you dyno before and after? What were the results in HP and torque gains? If you did not dyno, were gains noticeable. Lastly, did you think it was a worthwhile buy? Thanks in advance.

 

I don't think anyone here has experienced any significant gains from aftermarket cats. Our OEM cats have plenty of free-flow unless you're FI....

 

it will be worth buying if you want to loose money in the process. If your cat is fine stick to it.......

 

either leave it on (stock) or take it out compleatly (test-pipe) test pipe may be loud tho..

 

I've had an RT cat for 2 years and I can't tell the difference in power since I installed it with the rest of my exhaust parts. Most people complain about them breaking but I haven't had any problems with mine yet. I recommend them but I'm probably the only person on here who does

 

Thanks for the info. I will stick with my OEM cat.
