No exhaust

Cleave - Is that your truck in the photo that Jackrook posted? Are those Dune Grapplers?

They do but you can limp a plain to the ground. I just think it sounds bad IMO well I used to do it in high school with old wore out crap, why I personly don't like it. I can't talk to loud I have not Listent to a 6.2 live.

Haha... even if it were true, I'd rather it happen to a vehicle on the ground than in a plane. LOL

It is true but probably because of full throstle and g outs they explode

Yeah, those are dune grapplers

Stock size, 315/70R17? How do you like them compared to the OEM BFGs?

I believe the burning valves come from the old school vehicles, you could only tune carbureted vehicles for one set of conditions, and your tune would only even be worth half a crap if you did it on a dyno, tuning in your driveway was about as good as not tuning at all, if you had a more free flowing exhaust ambient conditions affects how the vehicle is running much more, so if you tuned your vehicle at 98° in the middle of the day then when it was 20° in the middle of the night you would be running very lean, causing high combustion chamber temperatures and the burning of valves, now with the air fuel ratio sensors that our trucks have in them the power train control module can compensate for any running conditions as long as the fuel injectors can flow the amount of fuel needed to compensate for those running conditions

Yeah, stock size, I like them better than the factory BFG mainly because they don't chunk, my dunes already have more offroad miles than my bfgs had and they still look like the day I bought them with the exception of a few cosmetic scratches, the bfgs looked like a pit bull had been eating them the day I took them off my truck, the dunes don't have the strongest sidewall but the difference between them and all the other dot options not including the general grabbers is nothing compared to the difference between all the dot options and the Baja and grabber race tires, none of the dot options stand up any better than any of the other dot tires in my experience, in all other ways the dunes perform exactly as the stock tires except in mud, mud+dunes=no grip, but you just have to have more balls and power through mud with them, they kinda float over mud so it's not as bad as having tires that don't grip in mud but also get bogged down in it so you get stuck

I think my next set of tires are gonna be the BFG all terrain KO2 once they are released, I've heard the non-raptor specific all terrains hold up better offroad than the ones that come on our trucks

What is so special about the KO2's?

i took my exhaust and have noticed a loss in low end power and if im in traffic idling going below 10 mph on 280 or 101 or anywhere in the bay and sitting for more than an hour without the windows open you can tell some exhaust is coming in. im currently saving for a turn down. only problem is it sounds epic with no pipe and when you put the pedal to the metal which is quite a lot, thats the only thing holding me back.

Does not sound like an old school muscle car.
