Its four bolts at the O2 housing and then slipping off the stock downpipe at the exhaust.

Its easy if you are at least somewhat mechanically inclined.

I dont think there is a how to on a downpipe but check in the how to section to see.

Really simple ill make a how to for you right now
1. Jack up front of car enough so you can get under use jack stands. To support car please.
2. Unplug cat sensor and unscrew it from the cat. Don't get it in dirt or anything I put mine in a rag.
3. Cut downpipe at bend or match up new pipe and mark out where it goes. Then cut there.
4. Top of down pipe there are 4bolts. With nuts I belive 15 mm for stock could be wrong. Mine arnt Orginal anymore.
5. Slide down pipe out and replace with new one. Probably going to need it welded on to stock exhaust with the reducer to stock back. Or if replaceing 3 inch all the way just welded up. And change 02/ downpipr gastket. I do everytime I get it off.
6. Put in o2 sensor you removed and plug back in once tighten down snug.

Tip if you have a smog state.
I had local shop weld on a flange on my 3inch down pipe and stock downpipe and the exhaust pipe where they meet At. So when I need to swap to my stock for emmission I just unbolted. And rebolt takes me 15 mins at Max with a air tool and extensions

Took me maybe 2 hours tops, and most of that time was because the bolts were a pain to get started. It was one of the first things I did, no need for a how to since its four bolts and a O2 sensor. You shouldn't have any problem doing it yourself

^x2 ?

4 bolts, an O2 sensor, and maybe the power steering oil cooler if you find it gets in your way.

There's no cutting involved.

To know, is to be hated.

Yeah oscard93, don't cut anything. Should be 4 bolts and a slip joint on the other end, shouldn't need any cutting

The slip joint or pin needs to be paid attention to. Make sure you have someone hold it with pliers when unscrewing it. We neglected it on my install in my buddys garage and we ended up having to cut the thing off and custom fit the new downpipe on. Was a big pain.

Yeah after I posted, I had a feeling somebody had already done some welding work or something to yours. OP, yours has the factory 2.25 inch slip joint right? If so, you should be good to go after reading these. You have your how-to now for the most part, just without pictures which wouldn't show much

I'm surprised no one said to soak the nuts/top flag nut in PB blaster. You will hate life if you snap one of the studs.
