OPEN DOWN PIPE, 1999 6.5 turbo diesel
I could not help but record the open downpipe, following the removal of the soot trap, I am sure everyone has done this. Never thought these baby diesels could sound like that. I could not resist and then hooked up the sound to a big speaker system. NICE bass! TRUCK DETAILS: This is a 1999 Suburban 3/4 ton 4X4 Fleet truck, no frills. Beastly 4:11 final drive gear ratio, neak breaker. Old NYC Police unit with snow plow bracket. Stock towing package, never had a receiver in it in 10 years. 99,900 miles, still under warranty! Notice the self-discharge fire extinguisher attached to the intake cover. All I did was remove the air box top, trim the expansion chamber (or some call it the turbo muffler, didnt seem to change) and do a soot trap delete pipe.
