Hi Flow cats
Hi Flow cats
Can someone point me in the direction of a good Hi Flow cat. I want to buy them offline then go down to a local shop and have them welded on. I have a 07 HD f150. Also I need some help with the whole installation process. What will they be removing and replacing. Other than my previous cats. Is it as simple as remove old cats weld new ones in?

as in we talk about this almost daily. like darren said, search. i personnally have said alot to use these. not to sound rude but its not a new conversation.
as the install, if you have stock manifolds then yes it is replacing the stockers. you will need to locate the 02's behind the cat by welding in 02 bungs but any solid shop can do this.
good luck and hope you like the new found sound.

I love my 94106 Magnaflow Cats, I had them installed with no 02's, I had them shut off the o2's with a custom tune. One of the best mods I have done.

The 94106 that Darren mentioned is what I'm going with also.

I had the same cats welded on about 2 months ago. The shop welded the O2 bungs right after the cat. No CEL just like Darren said and I recently passed inspection/emissions with no problems either.
Go to Performance Peddler, search for part# 94106 and use discount code: clubgp. You can get 2 cats for about $95 plus shipping.
