i have a magnaflow magnapack catback and was wondering if anyone has the MAC catted H pipe? is it decently loud but not obnoxious? also with the catted version you dont need any type of MIL ellimiator correct?

The question of whether you'll need MIL eliminators depends on if you throw a code or not--seriously....some people don't end up needing them and some people do. I've seen 3 cars with aftermarket pipes and cats need them and 7 without the codes thrown. I guess it is somewhat up to the car.

I've got the UPR catted X-pipe and didn't need the O2 sims. I just reused the stock rear O2 sensors.

I didn't need mine at first. Now I have a MIL all the time, even after clearing it numerous times. My exhaust is also making a really bad noise and I'm almost positive it's something loose in one of the cats. This is after only like 5 months of use. The sound is ok, but I think I'd try a different brand. Maybe UPR, BBK, MRT, or Mustang tuning.

FWIW, MRT catted H here. Uses high-flow Magnaflow cats I believe... No MILs, passed emissions sniffer test, great sound, good fit, stainless...

I have the mac catted h and I have had no problems excellent sound, no leaks with my mac lt headers and magnaflow catback, it's not overly loud with the regular magnaflow catback, but I know the packs are louder. I think that the fact that it has cats will make it not overly loud, JMO
