What is the best Exhaust for hp gains with a full cat back exhaust?

 

the charts say stillen

 

The Greddy EVO II IS THE BEST FOR ALL APPLICATIONS WITH OR WITH OUT FORCED INDUCTION..........

 

Hi there gumpdriver, hows it going?
I've had good luck with my Stillen Cat-Back & R.T.Cats Combo...

 

I just installed the Borla TD..i feel the increase in HP from a takeoff, and i absolutely love the sound, only other performance mod is Ztube

 

What are you basing that on?

 

What year and model do you have? Do you have any sound clips? How would you compare to stock sound? I have an 05 6MT coupe.

 

It's an 04.5..unfortunatly, no sound clips..but throughout the lower rpm bands it is much throatier than stock. At higher bands it's much deeper. The car also feels quicker and more responsive throught all RPM ranges (maybe im hallucinating, but i do feel a difference). No complaints at all..love it

Hope this could help

 

I wish I could hear several clips with sounds. While I would like to get HP increased by changing exhaust, I dont want the stock sound to be altered that much. I hate cars that sound like they are doing 80 when they are just doing 10 (riced shiet). Is there any exhaust that is close to the stock, but gives more HP?

 

Borla or Fuji sounds like a winner then 6MT.

 

You can also go to Borla's web page and hear a good sound clip of their exhaust. http://www.borla.com/

 

To bad their compact clip sounds like a civic...

These are 350Zs, but it should give you an idea.

 

Which exhaust has that or close to an " exotic " sound like the Lambos or Ferrari? Which has the deep V8 sound like the Mustang or Camaro's?

 

I seem to recall, from those clips above, the Stillen & Fujitsubo (Borla would likely fit in here too) were the deeper (low-freq.) tones.

Most of the clips on the bottom fell in the higher-freq. range that comes across like 1/2 an IndyCar engine or a sport bike, such as the Apexi. The Pro-1 (not included above) was at the extreme (louder) end of this sound range without the baffle. In other words, if you like the Apex and specifically want something loud, you owe it to yourself to hear the Pro-1. Intoxicating sound. If I only drove on the track, it would be my choice.
