I have a 95 suburban with a 350 tbi. I want to put aftermarket headers on it due to an exhaust manifold leak that i have to fix. What do you guys do with the aluminum pre-heater hose that comes from the exhaust manifold to the air intake? I have seen several pictures where they just leave it of. I thought it was kinda important to warm up my truck to operating temperature during the cold months. any opinions on that?
