Pypes High Flow Metallic Catalytic Converter Kit (86-10 All)

6 More Questions

I have a 03 Cobra with a SLP catted midpipe and catback and keep destroying the cats. Will these fit in my setup? I don't recall where the O2 sensors were positioned in the SLP setup and these cats have bungs, is there a way to cap them or do I need to relocate the 02 sensors to these cats and plug wherever they are in the SLP setup? 1 answer

• The Pypes High Flow Metallic Catalytic Converter Kit can be used to replace the cats in the SLP Catted Mid Pipe. These will include bungs to plug the O2 sensor holes if needed.

if i install these on a mustang that isnt naturally asperated will it affect the sound I have a 05 GT and planned on installing the exhaust before major upgrades like a supercharger but I plan on installing one. will this affect the sound negatively 1 answer

• The Pypes High Flow Metallic Catalytic Converter Kit (86-10 All) will not negatively affect the sound, since this has cats it will not be as free flowing but the sound difference is very miniscule.

long tube headers? Will adding this stop the check engine light that comes on after installing long tube headers? 2 answers

• You are going to have to Install these too and then get a tune up and that gets rid of the check engine light and tunes your motor to adapt to the amount of air flow that the cat censor is reading and what that means MORE POWER

• Yes and no. It depends on the codes the ECU is putting out. They may or may not be from the headers but yes a high flow cat will help on a mid pipe that doesn't already have them on. Not to mention o2's will read right then...
