Just curious what the best possible upgrade for the best exhaust sound without going intoa money pit.. Don't say straight pipes neither, it sounded like hell to me haha!

 

I would go with just a straight through muffler, not as loud as a straight piped exhaust but sounds good.

 

I have a 3" down pipes in to Y the up to a 4" .... into a Dynomax Diesel power muffler and 4" out to a 5" tip ........ big 4X6" K&N filter ........ she's got real attitude ...... now I have ported the heads and manifolds to match the gaskets ... can't wait to here this thinkg scream .... putting drivers head and manifold on today ..... maybe the other one on sunday after Church
