My 04 cts with the 3.6 through a code 420 yesterday which I read as being catayst system effiency below threshold bank one. Im assuming that means its converter time. My quedtion short of going to dealer is there any bolt in options say from rock auto or are they going to a universal type fit. I g
Havent had access to a lift yet to check theconnections out..Do they have bolt on flanges or w hat kinda of arrangement am I looking to find jesse
Yeah it drove and felt no different at all performance wise and hasnt come back on since i reset . I was driving it very heavy footed when it popped on. I might give it a few days and see what happens. If it does come back on i may go ahead and change both.im a welder by trade and can get magnaflows for 80 apiece with my company discount so welding on the flanges isn't no biggie then i know what i have. Jesse
Latest update is 420 popped back on. Im gonna order the magna flows and tig the flanges and what not on. The car has 150kmiles and had been babied since it was picked up at the dealership. Certainly could bennefit from a nice shiney new set anyway
Yrah i think the cheapest i could find that bolt right in were in the neighborhood of 300 a piece iuse a auto parts store for the business ie work for so we get a nice discount plus for that price you get a converter and a box but I'm a mechanic welder by trade so I'm good at adding the flanges and the gaskets and a couple other things while I'm there
It might be worth talking to a welder but If its a dude at home with a small mig or even worse just a buzz box it might be better for you to buy the bolt ins a welder capable of doing the job that needs to be done properly isn't exactly cheap but sometimes you can find one willing to take on a small side job at a considerable savings. Its not really that big of a job to weld up .but certainly a bad weld job is nothing but trouble down the road
I appreciate your reply and advice Kael and that's not a bad price for a bolt in option.I'm familiar with the magniflows and had good service out of them. Like i said i make a living for the last 30 + years working on cars trucks heavy equipment military equipment and i an also a certified welder for3 separate processes. Really the biggest reason i want to do it this way is the fact that i enjoying doing it plus the fact that i can and saving a few bucks is a plus
