Replacing catalytic converter - Magnaflow direct replacement?

I need to replace my cat, but I don't want to pay somebody to weld on a universal. Does the Magnaflow direct replacement bolt right up with no issues? Or is there a better option that anybody has used? Thanks!

Mangaflow is direct fit. I changed everything from the cat back at once.

I did the same, I just used a Gibson Exhaust which makes such a nice rumble around town

Just ordered a Walker (model # 15773) direct replacement from Amazon. If anybody else is needing a converter it may be worth checking it out. With free shipping through Amazon plus a $30 Mail in Rebate going on right now, it is $77.02. Not bad at all for a direct fit replacement. They are also doing $30 rebates for their Quiet-Flow SS muffler or welded assemblies.

I'm assuming I'll need a gasket.... do most of you just get them from a local parts store?

cat? who needs a cat under there....mines gone! I cut mine off, replaced it with a straight piece of pipe...added in a weld bung for the O2 sensor....bought a part off ebay, which basically pushes the O2 sensor away from the pipe and flow of hot air, no CEL...and no restrictions baby!!! Frees up the motor quite a bit if you ask me....

i got the same one off of rockauto.com over a month ago along with the walker(dynomax) cat-back. There arent any gaskets you will need at all. Your just going to need a 2.5" clamp to connect the cat to the down pipe. And good luck with the rebate, both the cat and cat-back had $30 rebates and i havent seen a thing yet.

It's not legal to run without a cat here, so it's really not worth doing that for me. Plus by the time you buy all the parts and pay somebody to weld (I don't know how) it ends up being close in price anyways. Plus the slight loss in gas mileage.

Thanks for letting me know about the gaskets, I just assumed I needed them. I probably should have gone ahead and ordered a catback too. Ill probably do it soon. Hopefully the rebates will come in, it sucks waiting on them forever.
