Here is the deal:
I have a 98' k1500 with the 350 Vortec. As of right now, it has dual Flowmaster Super 44 turndowns on it.
I purchased some Hooker Long Tube headers for it, and am totally reworking my exhaust from the headers back because of this.
1). My stock cats are rattling, so they need to be replaced. Here are they cats that I am looking at: http://www.summitracing.com/parts/MPE-53006/. Are those okay? I know the Magnaflow SPUN cats are suppose to be good, but unless there is a major difference I do not want to shell out the extra money. At the same time, I am not wanting to be a cheap ass on this project. If I need the extra expensive cats, I'll buy them.
2). Will 2.5" exhaust tube through the whole system cause me to lose low-end power? My headers have a 2.5" pickup, and my mufflers have a 2.5" pickup as well (I think.) Also, if 2.5" pipe is good, should I go with CATS with a 2.5" inlet/outlet?
If I need to do 2.25" pipe I can, but will I run into issues using it with the 2.5 pickups? And if I need 2.25", should I get the CATS with 2.25 in/outlets?
Thank you all for the help.
