Best if you hear clips of them and decide for yourself. Answers will vary depending on what the person likes and that might not be what you like.

If you claiming that much HP, I assume you have a big single. Not sure if there's any difference in what performs better with a single vs twins. In any event, if your curious about sound this site might be helpful. Has pics of various cat-backs with sound.

i think you should purchase earplugs and buy the cheapest one, since they are all going to sound the same in the end.

My vote goes to the greddy Ti, since its cheap for full titanium, great quality and great sizing. The only drawback with a cannister style exhaust is that it will most likely be louder than a true muffler style exhaust and the can is kinda big, but still good looking. Atleast, thats my opinion.

atr makes the best sounding flow-through mufflers i've ever heard...so far.

very quiet for a flow through.

Where can you get one?

from atr or horsepower freaks.

i'm actually building a catback for my fd. i'm getting the same muffler as in the 93+ supra kits, then having the local muffler shop bend the pipes.

atr charges like $400 for one bent pipe in their "kit", but the muffler is like $130 from horsepowerfreaks
