I had an estimate from JetHot, they can do the cross-x pipe and both headers for $175. Do you think this would be a good investment?
Yep!.....look into coating your I/C pipes also. "Wraped" mine and noticed an increase in performance above 35MPH when the air starts to really move.
You can get the wrap for $45ea you probably need 2 and your car won't be down waiting on parts. I wrapped my pacesetter header after I ceramic coated it $5 and it reduced the engine temp big time and did not rust out like everyone said.
