macdiesel You can't do it with a lift. The svt cat if huge. The flex pipe won't bend enough to fit coming out forward. The good thing is at least you only have to worry about the two bolts connecting the flex. The cat section itself has studs. I used a swivel extension with a 14 or 15 mm socket and a long ratchet. If you can get heat up there, even better. Like a small handheld torch.

When my cfm hfc failed I tried to get the hfc and flex out together thinking I could save time. I ended up using a sawzall to cut the hfc near the rack and pulled it out towards the rear of the car.

SVTFocus noob If you have access to a lift its not a pain at all, also if you got power tools it makes life easier, When I had to remove rear O2 sensor, I did it in my shop class and to remove flex from cat just held a box end wrench on back and then took air ratchet with an extension and bitch came right off. If you cant get to a lift it's still possible to, just a little more challenging, if no power tools get sum PB blaster or sum type of penetrating oil on there b4 wrenching at it. overall really easy task, if you ask me tho, everyone is different when it comes to this stuff.

ChrisRobin Ah ok thanks... good to know about the extensions. Yup, it's going to be a pain but I'll try anyway.

FLYLOW Imo not possible. The cat alone is a bitch to remove, the heat shield and sensors are always in the way of something, and if u pull everything though the front im not sure the flex pipes bends will make it possible. gl trying to remove the sensors with the cat pipe still in. 2 days ago I installed my catpipe back in for inspection and my shoulder and neck are still sored

Youll need a +12" extension and a pretty long tq bar to tq it out, and some chuck norris strenght. Soak the bolts in pb the night before and again like 30 mim before trying it. I used a 16" extension if a remember correctly (autozone, like $10)

sleepyboy I want to say I needed to use two extensions together but I can't remember. I definitely don't remember what size bolts they were lol. What ever the cat's bolts are is probably what size they'll be.

ChrisRobin Well let's hope the bolts aren't all seized up. Although since it's doesn't really snow up here and there's no salt on the road, it should be too bad.

While I'm here, what kind/length of extension did you use? Do you remember the socket size?

It's just so that I have all I need for when I attempt this.

sleepyboy Use extensions to get to it, makes it easily reachable.
12-07-2012 09:01 PM
ChrisRobin If you can't, how the hell do you get up there to the bolts??
12-07-2012 07:58 PM
sleepyboy It's a lot different. I doubt you could get them out together but you can always try. I had a pain just getting the cat up into position.

Marbs I took mine out together. But I have an 06, not sure that it would be much different.
