GrizzlyBear 04-18-2005, 09:00 PM Hi, I have a 98 Chevy 3/4 ton with the 6.5L. I just recently purchased a 3 inch down pipe and I had a question on it. Is there a gasket that goes between where the 3 inch pipe is flanged and connects to the turbo? I know when I have worked on tractors some have them and some don't and before i tore into it I just wanted to see whether i needed one or not. If I do does anyone have a part number or does a chevy dealership carry them? Thanks Jesse 69camarox 04-18-2005, 09:35 PM no gasket there joispoi 04-19-2005, 08:12 PM nope, reuse the factory v-band and you're set to go. If you're bolting up to the factory exhaust, have some extra bolts handy. You're likely to break at least one when you unbolt the back end of the down pipe... quantum mechanic 04-19-2005, 08:58 PM penetrating oil and an impact wrench won't break them.

Better than I thought. ):h penetrating oil and an impact wrench won't break them. bowtie 04-19-2005, 10:54 PM When I did my exhaust. I try to keep my bolts from breaking..

I do like PB Blaster on hard, rusty nuts and bolts. quantum mechanic 04-20-2005, 11:05 AM Did you clean the threads of grit as well? that can make a hudge difference. Plus things don't rust under the truck down here unless you drive through the surf.
