Re: 6.5L Diesel stock exhaust vs muffler and cat removed

These are my trucks. I have two 1998 GMC Sierras 2500. Only difference is one truck is the SLT trim. I have installed the SSdieselsupply 4inch exhaust on the green truck along with marine injectors. Both trucks have relocated PMDs and heath turbo masters.

Nice trucks, you must be a real fan if you have 2.

I would by another one myself. If I were to get another one I would get a dually and do dual stacks instead of 1 =)

I like Duramax's but they seem expensive to maintain if something breaks.

I actually have three of these engines. One is in my work van. The second pickup I bought for $400 because the previous owner didn't know about relocating the PMD, he couldn't keep it running. I have an Isuzu engine in a flatbed and that truck is great, it out tows my pickups.
