I have a 09 silverado with the xr1 and I'm looking to upgrade the sound..Don't get me wrong I love the sound I just want something a little more aggressive sounding...What are some other options I can go with?
if you plan on getting headers then you might just wanna keep your xr1.. theyll increase the sound by themselves.. THEN if you want a more agressive sound, try something else.. straights with headers will be extremely loud though
Headers will definitely increase your sound. If I were you I would get them and decide if you want a new muffler. If you do maybe try a spin tech? I don't know of any others that are much louder then an xr1, or any muffler that style
