Wrapping them might quiten them down a little, but it will also cut the life of the headers in about half and it probably isn't worth the difference. I'm actually going to be putting a Todd Co set made for a D1 on my D2 because I'm getting a steal on the set at $150.

The y-pipe situation is that you will probably need almost a whole new y-pipe. I'm going to end up getting one custom made that will probably cost another $100-150 (re-use my Magnaflow cats).

The only way to really quiten down the exhaust is bigger mufflers. If you're going for quiet, then throw on a Borla Pro XL (not XS) and keep the factory resonator. You might be able to fit another resonator on each side of the new y-pipe and it should be overall pretty quiet. I daily drive kine with a Pro XS and no resonators, so that setup should be a million times more quiet.

Oh, and don't even mess with shorty headers. Long tubes or nothing because shorties don't really flow any better than the factory manifolds.

Edit: Changed re-sign to re-use. Damn auto correct.

 

roller rockers....where are you guys getting them? summit? I can't find em.
found what only looks like yella terra ones (not even a manufacturer name), from a uk/ trv performance place but holey moley they are the price of 4 sets of heads.


also if i'm going that far, how bout adjustable pushrods? worth it to dial in preload or just get a set of new steel ones?

 

adjustable pushrods are to test the valve load, you want solid pushrods

 

test...oh I see...I thought it was adjustable to set follower preload. so not like motorbike.


only needed if going form hydraulic to solid...correct

 

alex, yeah trying to be unassuming in sound. so no go on wrap. muffling the back end is no biggie, but last truck I had headers on was loud loud up front after. a lot of differences though.
disco has a lot more sound insulation than scout.


those janspeeds are long pipe....still looking for dealers. didn't know about todd co ones.

 

todd-co I believe are just reworked headmans

 

That sounds right to me. The pictures look exactly the same.

Sounds good. I also shot you a video a few minutes ago so you could hear the lifters and I got my exhaust sound too, both driving and standing outside the truck. The video exaggerates the sound A LOT, but you can atleast get an idea of what they sound like. I personally don't think the lifters are hardly any louder than stock, but I'm also comparing that to lifters that were already ticking. I'll get it up in a bit.

 

Yea. The adjustable ones are so you can see what length solid rods you need to order. Kinda sucks, permanent adjustable push rods would awesome.

 

yeah, like bikes.
so needed for swapping from hydraulic to solid?

Here you go, man. Just remember, the video makes it sound WAY louder than it actually is. The lifters are barely louder than stock.
