Which high flow cat should i use with my dynatech long tubes?

 

Get the Magnaflow metalcore cats, they are the best! you only need 2, one per side, and they flow great and are made nicely. they will make your truck sound really nice and loud. their core density is real low for better flow.

Chech them out here: Magnafolw cats

I got those same ones and they are high quality! I only paid $78 per cat tho from some guy on ebay for the same ones... i couldn't find his ebay store tho.
Good luck!

 

Thanks for the link. I will look around for a good deal. In the meantime i ahave another question.
Is the maggie 94006 the same as the high flow 94306 just without the mirror finish?

 

honestly, what would be the point of getting a mirror finish on CATS? shiny finish=more cleaning=more bling, but who cares about CATS looking shiny?

 

Yea i had the magnaflow hi-flow cats with a DIDO with the x chamber high gloss finish muffler on myu 02, After about a week of driven , dirt and other stuff just cake on it anyways and you lose the finish. So dont pay the xtra money for it (atleast i want again )

 

I couldnt agree more! I was just wondering if the Magnaflow part# 94006 is a hi flow just like the 94306. It doesnt specify that on their website. They look the same just without the finish. Its also about $30 cheaper.

 

Do they have a spot for the oxygen sensor, or does that have to be changes with a tune?

 

The Troyer website recommends the 94306 cats for all 1997-2003 F150s.

The 94306 Cats are a different design on the interior instead of having a Non Flamable Matting holding the brick in place it has Wire holding the Brick.

Heres a Cad Drawing to kinda of give you an idea
