which way does it go on, theres nothing saying front back or arrows or anything to say which way it goes on? Get put on saturday cant wait.Hopefully the muffler shop knows Is there anything noticable about a high flow? Im gonna get sound b4 and after. hope it does something.

You'll notice a SLIGHT difference, especially if your current Cat is clogged. You really don't get into the performance gains until you open up the muffler. The two go hand-in-hand, but the muffler can still hold you back. Since you already did that, you may be more likely to feel it than someone who has a stock muffler, but I did mine in the reverse order. It'll be interesting to hear your impressions.

Red Baron...where did you get your CAT and how much?? I want a Magnaflow since I have my Magnaflow muffler. Hoping to get mine before winter. Thanks!! Good luck with the results!!

Got it at a local performance shop, Pro Auto Accessories it was $150 cdn and its gonna cost $70 to have it installed. I asked the muffler shop (that is a magnafow dealer) how much theyd charge me for it. $256 just for the cat

How big (long) is it?? Compared to the stock one? Am I going to need some extra pipe when I get mine? Thanks

The stock one was 4x8x24" the magnafow is 4x7x16". Not direct fit but damn sweet. Sound and perforamnce.
Maybe you wouldnt say that a cat would change it much but ...
DAMN did it ever, the sound? Bring on something that sounds better than dynomax and magnaflow combo. (Sound Wars?)
Performance? Well the old one sounds like theres a hard ball in it when i shake it, that was definitely cogging it. cuz it feels like iv unleased sum fearce when i drive "normal" or "performance". yamean.Cruisin is koo. Tried the new mod a couple times gettin on the highway against those willing to "try". Was in the passing lane before all were thinkin about merging on.
What should I do next

Sweet! Sounds like you benefit a lot from it. I can't wait to get mine! My CAT is probably original right now, I expect to feel a difference with the Hi-Flow. Maybe a slightly louder grumble would be nice too.
