k..some may know..long story short my truck had a few mods(2/3 drop, and full exhaust) when i purchased it. I bought the truck from a guys mother who sold it on him, and he wouldt give me any info on it or stock parts etc, he was being a 32year old baby.

So..I know it has duals...and edlebrock shorties....But what about this stuff inbetween? these look like stock cats and x-pipe?? I know it sounds dumb....but I cant see any marking on the cats(the bottoms) to indicate anything..want to make sure Im running high flows cause Im getting PAcesetter Long's and wondering if I need cats too....Truck is a 99 5.3 2wd

what do you think?

 

i know that x-pipe isnt factory

 

not sure who made the cats, but that's a magnaflow x-pipe.

 

I have to agree that doesn't look stock. I can't say if the cats are high flow or not, but I don't think they look stock.

 

i wana say those cats come on the v6 trucks

 

are they smaller or higher flowing?

 

those cats look like my older trucks cats I use to have. If they aren't stock I would gaurantee their not high flowing. But as they said that looks to be a magnaflow x pipe, those cats could be a muffler shop add on but their nothing special. replace them or get rid of them.

 

those converters look different than the ones that were removed from my 02. just a thought.

 

yah this is my delema......noboby really knowss..haha

i think im gonna leave them, and when i replace my short turd edelbrocks with pacesetters i'll get two new cats...sell the ypipe and old headers to someone else

 

That is a nice looking system. None of that exhaust is stock. Those cats look like my old Magnaflow cats and the X is a Maggie. If you plan on getting LTs, I'd toss everything and start fresh. If you plan on keeping the cats or getting new ones, Magnaflow has some polished SS for around $80 a peice. You can also save some space buying getting a Magnaflow di/do muffler with a built in X pipe.

Nice truck.
