So I finally went and had the muffler cut out and all I can say is WOW! It sounds awesome! I still have the factory 3.5" pipe but still seem to notice a SLIGHT power gain. A couple of hills where the truck normally downshifts it seems to chug right on through now. Hopefully I'll get a little better fuel mileage? Maybe it's all in my noggin but darned if it doesn't make me giggle anyway. So far I can live with the very slight drone too. I don't pull anything heavy either (trailer and all equipment probably weighs between 2000 to 4000 lbs.) so it's not as pronounced as most of you guys would experience while pulling RVs and such. Anyway, happy rumbling! (and whistling!)
The ebpv when its warming up sounds awsome....not sure how my neighbours like it...but, I could care less what they think, but I do try and idle away from the house at 06:00
After I did my muffler deleate, I couldn't stop rolling down the back window every time I was near a wall or overpass. Wife would just roll her eyes. Need to start acting my age.
Yep, I've only had my stock '02 F250 for 2 months now and the muffler delete was my first "mod" ... really not too much louder but as you said, but it does seems to move a little easier accelerating down the road ... and I now hear the turbo spinning down when I turn it off...I'm 51 and this diesel has brought out some of the kid in me too - I like it!
mtdigger, the muffler shop just cut my muffler out and welded in a straight pipe leaving the tail pipe in place ... seems that it would create less droning in the cab with a tail pipe as opposed to exhausting under the truck without one ... just depends on what you want to hear I guess ....
