The herd has gone with the Magnaflows, Ravens and Flowmasters. Has anyone tried the Race Magnums?

 

I have the race magnum on my 01. I wasn't crazy about it at first,(had Borla on my 94 L and loved them, but they don't make a two in two out with 2-1/2" pipe). Dynomax is a straight through design with some kindof ceramic stranded packing, which I think is breaking up a little. Don't let this scare you it is sounding better and better the more I drive it. It is louder than the magnaflow, and has no resonance noise. Overall I like it!

'96 Honda CBR 600, Jet kit, M4 pipe (Kills me to own Jap Crap, but it sure is fun)

 

NFS, I have them on my truck, but I used them to replace the cats. I made a pretty detailed post about them over on the "JDM" site. Here is the link:

I'm confused! If you turn off o2 sensing, aren't you not allowing the computer to read that data to make engine decisions dynamically (sp?) What is o2 sensing used for on a chipped computer?

We are not turning off the reading of the O2s. There are 4 O2s, 2 "upstream" and 2 "downstream". The upstream O2s are used by the PCM. The downstream O2s are just used by the OBD II portion to see a difference before and after the cats. When you remove the cats, we just shut off the OBD II cat test, so it doesn't look for a difference anymore.

Race Magnums are now on and I must say they are great. If you want to listen to classical music at 80mph they are not for you. At idle they are deep and throaty.
