Headers, duel low restriction mufflers, sealed intake to the outside as large as you can get,(open filters in the engine compartment suck hot air not good for performance.)I want to get the best Intake and exhaust I can get for my truck...For those who don't know; it's the 3.5 liter 4dr Z71 4x4 Colorado. Suggestions and experiences please.... Performance is the key here, not sound or looks!!!
I put a K&N FIPK on my wife's 2001 Suburban w/5.3 and with that alone it was a night and day difference. Exhaust, TB spacer, and Hypertech programmer will complete the upgrades to come.SSgt
I am in the same position looking for intake and exhaust for a 02 suburban 5.3. Let's see what folks are saying.
I think I am sold on the KN, but the exhaust is up in the air.
Nope, its under the truck!:lol: But seriously, I went with a K&N filter element and after speaking with the guy at the smog shop today I'm going with a dual cat exhaust system using the stock manifolds. He says to be California legal I can convert to dual exhaust as long as I put a 'balance tube' in the system.I think I am sold on the KN, but the exhaust is up in the air.
