Does anyone know a company that gives both HP + Sound ?

I tried "fox" company they said " We are able to maintain the desired sound , but HP we can't do that since theres nothing from germany regarding LS 460"

Any LS 460 exhaust tuning companies in USA ? Australia ?

I found a website that has all that but its in danish.

to be honest i really wouldn't bet much on noticeable power improvement from exhaust

 

you will never get any increase on the power, if you want some sound only you can do it.

 

You'll get a slight increase from custom tuned and equal length exhaust headers. I doubt you'll get after-market headers though as there wouldn't be much demand for this type of vehicle. Custom would not be cheap. If it could be done, you'd be looking at $3K +/- as they would be one-offs. Make the engine breathe better and you'll get quicker and cheaper results (and more available).

Wow that actually sounds nice. Who sells this again?

 

Depending on the type of exhaust system there will be a slight gain in HP but only if your air intake is capable of the air flow required. An aftermarket air filter is a must when installing a aftermarket exhaust.

Same theory applies when adding an aftermarket air filter, filter alone will not help unless the exhaust is changed. It's all about the air flow.
