Magnaflow DIRECT-FIT CATALYTIC CONVERTER

Ive had an exhaust rattle for the last month and have determined it to be the pre cats on my 2002 Overland. The muffler shop quoted me $700 to replace the pre cat assembly. That seemed high to me. I found that magnaflow makes a "direct replacement" and am wondering if any one here has done this themselves and how much of a pain the the *** it is. Is it unbolt the old and bolt in the new? Any cutting involved? How close is the fitment to original? At some point I wanted to to a cat back, might as well do it all together...

The link does not show a price. When I changed mine on my 4.0 the exhaust itself was over $400 from NAPA. I took it to a dealer that installed it for me and it took them a long time to get it installed so I would say not an easy job. He was having problems getting the system not to leak. $700 is probably a pretty good price with it including the part.

If you don't have time to do it right the first time, how do you have time to do it over.

Completely useless.

Click the link and read his post. He has a 4.7L that's for the 4.0.

I believe you could save some money by having the precats cut out and replacement cats welded in. Replacements could be Magnaflow universal cats which can be had for about $100 or less each. It would not be a big job for any decent muffler shop to do the cutting and welding.

If you decide to try to do this, email Kolak (kolak@aol.com) for a price on the appropriate universal cats.

I wasn't quoted any less than $100 per cat just to cut out the old and weld in the new. The problem is that they are so close to the oil pan, it's difficult to weld around it. $700 sounds about right for that job with their markup on parts.

As for the direct replacement linked in the op, you'll still have to cut behind the y pipe and weld the new one in.

Send me a PM and I'll price the complete Magnaflow assembly for you. Also I have the Magnaflow high flow weld-on precats available if you'd rather go that route.
