They absolutely hold their own. After you build a vette and the Rambler you need to build the WS6 and it needs to sound like this monster

 

Congrats! After a lot of research I am also going with Borla S Type Axle Backs. Still sticking with the Airaid CAI and need to send my Diablo inTune tuner back to Bama to get it programed to my GT. Other than that, it's staying stock. I designed a trunk panel and had Tim Miller make it. I'm also getting the engine cover painted by a company from Indiana called Wicked Dipz (found them on facebook) - I had them paint my coil covers.

 

I've considered it for sure, I want to keep the WS6 nice though, only 8500 miles on it, I want to keep it a low mile cruiser

Built that Stang though

 

Nice, I think the S type is hands down the best sounding exhaust for these cars, that is what I will be going to after I get new wheels and tires. but I think I am going to do the cat back because you get an X-pipe with it which is nice. I like the X-pipe sound a little more on the 5.0 than I do the H-pipe.

 

Oh it is going to get built lol. I plan on doing a 624hp ford racing supercharger and then doing a CAI for it, smaller pulley, GT500 fuel pump if needed, one piece aluminum or carbon fiber drive shaft, stronger clutch to handle the power. I would like to be right around 550ish HP to the wheels, I think those mods should get me there if not well over. I want it to still be street able since it is a daily driver, however when I do go to the track I would like to put down some decent numbers. And having the ability to beat any car from light to light would be nice to lol
