Exhaust will probably be my first upgrade mainly for sound and no need for tune(with MIL eliminators), so i keep the warranty... anyway my question is if i want to replace everything from the stock manifold to the stock mufflers, what do i need to buy? I like the sound of the O/R H with stock mufflers, but that only goes to the axle.... I noticed how f--ked the bends are over the axle and wanted to get pipes that are smoother possibly freeing more hp? any input on what i could buy or if i should just go with the O/R H? that sounds weird but i think it makes sense....

 

This is a pretty good deal here: https://mustangforums.com/m_2098261/...tm.htm#2098261

 

Just curious...If you replace the manifolds with headers, and add an offroad h or x, would it void warranty? Cause I still take my car in to the dealership for oil changes... I just was curious if the dealership would give you alot of crap over the exhaust.

The dealership answer is probably going to be YES. Do a search, there are tons of conversations about this very same thing.
