did the shorties not as much power as longs of course but the cats are safe for smog and still have some power

 

Installing the headers does not require a tune right? Will the car still run fine with out the tune, or will it be lean?

another question about those shorties, im about to bite the bullet on them. How was the change in sound? different tone? I actually heard that they make the car a little quieter. True?

 

bump to my previous question

 

How to describe the sound of them....

I have GTA's... and it took the GTA's and made them growl deeper and louder. I had a cop pull me over to simply tell me he liked how my car sounded when I got on the gas.

 

I could definately hear the difference before and after. Deeper, more growl at higher rpms and more of a lope at idle. I guess it may have made my car little louder, but it definately made it sound much more aggressive.
