TI Mod or Xpip
 

Well im kinda torn between the two. I dont want to do both because of sound. I dont want it to get loud just deep and nice. I was thinking of doing the TI mod driving 128 miles to san diego have 74Weld do it for me at 250.00, or my second option is do a Xpipe as close to the headers as possible maybe cost me a bit less and hold on to my cats if i have any emission issues. Not sure which one i want to do. My first thing was TI mod but since the exhaust flows well enough i can do an Xpipe and get it tuned for it as well and pick up maybe 8-10rwhp. I doubt i would pick up anything on the TI mod.

I'm not sure what you mean by Ti mod. Don't you already have a titanium cat-back exhaust? Does the Ti mod eliminate the cats? If you live in CA, smog techs are supposed to verify that you have the OEM exhaust manifold or shorty headers, and twin cats. If not, you could fail the visual.
