is there a post with alot of the different set-ups.im wanting gain all i can as far as horsepower goes,BUT i want that sound that the older 5.0's would make,is there such an exhaust out there,from the headers all the way back?

do our cars use 4 o2 sensors?can we delete the second o2's and the cats?i have no emissions where i live.

 

I was wondering the same thing about the sensors. If u like the LOUD raspy sound like I do, id say go with SLP Loudmouths. As far as adding an X pipe with tune...does anyone know the gains for this or if i would be losing ft lbs?

 

i have a very loud z28 now,with the gt i want something that sounds as close to the "5.0 sound" as i can get,i love the way those cars sound,so deep and mean!

 

You're not going to get the sound of the older style mustangs as their mufflers were in the middle of the car, as the 05-08's are at the very end. If you want a deep sounding exhaust a offroad H pipe is the way to go and probably either corsa or borla/FRPP axle backs. I have the H pipe and the FRPP stingers and it is deep and sounds amazing but other people don't like that sound and do a X pipe which sounds a little raspy. Either way if you go with an offroad H or X you'll pick up around 10 hp with the X pipe giving maybe 1 or 2 more.

 

5-7 HP from an o/r setup

o/r H pipe+pypes mid muffler system=as close to a 5.0 as you will get. Now that will sound like sex and if you want to add headers that only the iceing on the cake your already there.

 

My off road X made no noticeable difference in HP. However I did drop about 50 lbs in weight! It just got loud and raspy, Ihad to take offmy Summit muffs and put the stockers back on, it was way too loud and still is.
