Magnaflow cat back
Question for ya all. I bought this Magnaflow system sometime last year.
and it came with an xpipe as part of the kit.
Now I am looking to add headers to the exhaust and cant figure if long tube headers would connect to the xpipe I already have, or just get headers and a new xpipe. If anybody had insight to this I would appreciate the help.

If the headers have the factory pick up points for the factory position for the cats then, yes most definitely. Magnaflow does not make a shortened mid section as of yet. But who knows they may make a shortened midsection in the future. I hope this helps!

Thanks for the help, but I remain confused! Will headers bolt up, because yes they mount to the original downpipes, or get a set of headers and a new xpipe?

They will as long as, the end length of the collector is of the same length as the factory. You may have trouble finding a manufacturer that will go back that far though. You could always have the Magnaflow midsection cut back at a local exhaust shop.

I have the same Magnaflow system. If you put on long tube headers, you will have to use the header manufacturers x-pipe and hook it to the over the axle pipes which then will run it thru the Magnaflow mufflers. So buy your headers with a 2 1/2" x-pipe and you are good.

You have a good point Rick. If you buy a set of LG headers use their x/h pipe if at all possible. Same applies for a set of Kooks or any other brand. The fit and finish will be much better.

Alight, I think I got it then. I will need to get the header manufactures x-pipe too, or find a header that reaches the stock hookup point the factory h-pipe mounts to. There goes my thought of a set of $900 headers. Im trending towards kooks, but with headers x-pipe and cats its closer to $1400. Thanks for all the help too, this forum and you all rock.

You almost got it. You need headers and an X pipe that END where the Magnaflow X pipe ends (at the beginning of the over axle pipes). It would be nice if the Magnaflow X pipe ends at the same place as the stock X pipe, which is where header X pipes are designed to end so you can use any over axle pipe as long as it's the right diameter.
