I would love to see a 3.5" Titanium unit except I think with a dual muffler setup it would be really costly around $3k+ I really dislike seeing single pipes on yalls cars. I much prefer the dual setup despite the weight that comes with it. I could understand why people would not go for that reason as well driving in Houston with a low cars with dips in the roads could be make for some good scrapping. I always like to refer talk about this article with friends; wish their were more references with comparisons from stock-bpu-apu. http://www.superstreetonline.com/how...ust-test-tech/
