Hi guys, long time lurcher, first time poster. Alright well I just bought an 02 GAGT and the acceleration is terrible, like lots of people have had. So after searching for about a week I see the majority of people have had a clogged cat and replacing it fixed their problems. So then I searched some more to see what type to buy, but I am confused whether to get the universal magnaflow cat or the direct fit magnaflow cat. I am planning on installing this myself, so would the direct fit be easier to replace? I'm assuming that if i get the universal i have to cut the old cat out and weld the new cat in. Thanks for any input!

Don't replace it without testing it. I think you should drill a hole right before the cat and put a pressure gauge on there to see if it is clogged causing back pressure. Then plug up the hole with a screw.
