I was wonder which exhaust system or muffler is the best out there and increases the most hp on any car.

 

what kind of sound do you like? high screaming sound or quiet but deep sound? also what kind of car? if you want the loudest and good performance i'd go with R&D Thermal, very very loud (screaming sound) thats what i have. Deep, i'd go with DC sports or Greddy.

 

First off dont get a universal muffler whatever you do. The greddy has an awesome sound, my friend has it on his integra. I have a skunk, and am really happy with that also, it all depends on what type of sound your going for.

 

sound, and the look......

 

the best? hytech

 

and if I don't care about the sound?
flowmaster 2.5" straight through?

 

How about Supertrapps instead?

 

oh i was looking for a good deep and loud sound that could be heard from like umm blocks... lol and would be the best increase of hp .... thanks for comments

 

oh yeah on any car and no price limits

 

You can't go wrong with a custom system like Hytech or SMSP.
