High flow cats

[DaUsedMCR]

tired of the no cats smell with the headers. im looking for some high flow cats that would get rid of the smell and minimize horsepower loss... would these work?

or are there any other ones i should look at? i want to get them welded in to the LPP Y-pipe

find out what size your LPP Y pipe is..

Peep this cat

its 3". the guy at the exhaust shop quoted me $360 installed for 2 high flows, and the adjustment to stop the Y from hitting the crossmember. i thought i might be able to find them cheaper, so he said if i supplied them, he'd weld them in and fix the Y for $100.

Have no idea how long they would last.

I used those similar type cats on my old 90 Iroc and there performance lost was minimum and they worked well enough to pass a sniffer test. For the cost I say go for it, probably won't find anything cheaper.

If you do go with them and put them in that Y pipe please post of pictures. I am interested in those headers and Y-pipe and want to do the same thing so the more ideas the better.

Acording to magna flow those wont work with my truck, 04 5.3. They said only the largeer universal cat will do. 51019 maybe? Like a $149 a piece. Sucks, my exaust guy told me $500 total. $300 for cat $150 for work. Ive been tring to figure out if i wanna weld em in or just have him do it. Not dure if the info will help ya or not.
If you try the ones your looking at newegg.com had them even cheaper.

Side note,i just saw that spintech makes high flow cats too, little cheaper then the magna's. I will give them a call tomorrow.
