2 questions please help???

[Evans SRT10]

First ?, I did full 3" exhaust on my truck with no cats, I built my own H pipe. ? is.....is X pipe or H pipe better for our trucks? I did some research before goin with the H pipe. From what I found seemed like it made a little better tourque than X pipe. Any input would be great. Next ?.......I am gonna change my stock 4:10 gears to 4:88. What does it take to do this other than the ring and pinion seals, bearings, shims. What needs to happen with the carrier is it big enough also the stock locker, will it hold up. Again any input would be fantastik. Thanks, Sean

can't say for exhaust without more info... what manifolds/headers? which mufflers, any resonators?

for the rear end, you will need a new carrier... the 4.88's won't fit... but if you want to re-use the same carrier, you can step up to 4.56's...

x pipe h pipe your not really gonna gain a ton of hp , probably a couple hp more sound than anything here there, but going to a 4.88 requires new carrier and bearings
