Test Pipe and Manifold Recommendation

[moore.speed]

For a while, I have debated whether I should get HFC's, resonated test pipes, or Motordyne's ART pipes. I understand the differences but mainly care to know is the price tag worth the purchase?

Ideally, I would like to go with the ART pipes, M370 manifold, and Uprev tune at once. But is the extra money spent worth it? Would a cheaper option like resonated test pipes suit me well and is the manifold worth the $614 price tag I see online?

Currently, I have Stillen Gen 3's and Fast Intentions 18" resonated cat-back exhaust. I don't plan on going much further with performance mods, at least for now. Overall, I want a well performing car that sounds great, as well.

Opinions and advice is appreciated. Merry Christmas (Eve)!
