I am no stranger to engines or power, being a mechanic myself. My question however, is what kind of luck has anybody had with exhaust on the 3.7. First off, how good can it sound? Secondly, I know with a lot of v6's I have dealt with in the past, a more open exhaust, such as true duals, can actually cause it to lose power, by taking away backpressure. I've seen this a lot on GM's 4.3L. Any info someone can provide me would be great. I don't expect huge gains, I know that exhaust and intake and sorts don't add the "amazing performance" many claim they do. But I love loud exhaust, and a healthy engine. Also, what brands have given people the best results on the 3.7? for right now, headers are out of the question. PA is very strict on emissions anymore.

 

Well... Do you know where I can get HEADERS for my 2003 Dodge Ram 3.7L???
