I am all stock in teh exhaust department. Too many to choose from. Trial and error on exhaust can be mega &#036;, so i will wait a little while longer after more research. I guess the decision has been made then...4.10&#39;s and a tune. Thanks all. I will post next week when I get all of that done.

Nice wheels gearhead, those are the ones I have. Do you know where to get the polished ones? (they look chrome)

Thanks, I don&#39;t know where to get the polised ones I&#39;m thinking about having mine polished.

Two inches of tire will make more of a differance that you think. I went from a 30" to a 31.5" and I noticed about 1000 rpm.

I just had a thought Just put some boost in it and that will solve all your problems.

I think you meant to say 100 RPM change. 30" tires on your truck would have been 2050 RPMs and 31.5" tires should be 1950 RPMs. Go HERE for a calculator.

Yeah, I ment 100 rpm

thanks for the correction I got carried away

Awww crap. I am a freaking moron. :nutz: :whack: All this time I thought I had 3.73&#39;s. I just found out I have 4.10&#39;s&#33;&#33;&#33; :thumb: Whooo hoooo&#33; :smile: I knew it was quick off the line, but damn. :burnout: I sit right around 2400 at 70 in OD w/28" tall tires...
