I'm in the market for an exhaust system and I want to spend less than $1000. Which one have the most power gain? Amuse? Spoon? Veilside? HKS? Mugen?

 

single outlet will give you more HP the duels. i think the veilside weighs 6 pounds but hella loud.

 

try searching it....the single outlet will give you more power if you dont have fi, but the amuse and apexi i believe are pretty expensive...apexi might not be that bad, but not sure..you should be able to find some results if you search though....dont expect to see big increases either, theyre pretty small but weight differences are important
