i think they got higher pitched and raspier with the gta's.

 

I just installed the FRPP GTAs on my wife's JDM Saleen S/C'd Stage 2 06 GT yesterday. Only paid $289 shipped to my door. Fit was very good. I am very pleased with the results: not loud at idle, rich deep tone w/no drone at cruising speed, and quite noticeable at WOT. Her car also has a Magnaflow Catted X-Pipe w/stock manifolds. I highly recommend this combination for a daily driver.

 

Just ordered the Supreme Performance GTA's from Ninosport on Friday ... they have inventory (for now)

 

OK. I bit.
I just ordered mine today. My girlfriend is going to kill me! LOL

 

Installed mine over the weekend. No instruction sheet, but figured it out. Definitely more base than stock. Nice tone and generally pleased. Next up is to install the x-pipe and the JBA equal length shorties.

 

i just installed them with an O/R H-Pipe (no cats)

best setup i've had thus far. there's barely any drone so there are no headaches inside the cabin yet the car is still very loud on the outside. i love it - it SCREAMS at WOT in the upper RPMs without the cats - even more than my Flows did.

 

Any HP gain from GTA's or any other axelback / mufflers?

 

No, not really!
