I still have the stock factory exhaust on my 98.5 24 valve. I like the way it sounds and have thought about changing it out but have wondered if I really will see a performance improvment other than exhaust note? Have you guys noticed any difference in performance with the bigger exhaust systems on your diesels?
With no other mods, it will just be for sound.
And cooler EGT's. I have the 4" MBRP straight pipe kit on my '01 and love it. Cheap ($260 or so) and easy to install.
