Ive been bending my mind around what I should do to modified the engine first. Already have a CAI and exhaust but have been deciding if I should install the Spyder Chrome Exhaust Header and Y-pipe combo....
any suggestions?

 

Don't waste your money, you need to read more. Headers won't help. Look up '00VI or V1.

 

headers rnt really worth the trouble but a y-pipe is a pretty easy thing to bolt up as long as u dont have a ton of rusted exhaust bolts/studs

 

A Y-pipe is the cheapest way to get real seat of the pants improvements. Just take a look at the factory one compared to just about any aftermarket one. There are two small cats on the factory Y plus really restrictive crush type bends. An aftermarket one eliminates those and usually have mandrel bends. I know my SS Warpspeed did anyway. If you live somewhere that does inspections make sure to drive it for a while to heat the main cat up enough to be effective before the inspection.
