interesting...i dont really have the $300+ to spend on the jet chip though
:( (yet :) wonder what adding new exhaust or just a muffler would do to
up that even more?
btw, just got back from a muffler shop. the guy said he could run 3" pipe
(single exit) from the back of the cat with a new magnaflow XL for $300
installed. this would be with aluminized steel...does that sound about
right? and would that be too much pipe for what i plan to use my truck for?
i.e. ---
> You only loose backpressure when applying large exhaust system without
> proper amount of exhaust.
and could someone clear up the "see-thru" vs. non see-thru concept? i have
read that a see-thru really isnt any better than any other turbo style
muffler, just wondering what the performance implications would be...
thanks again steve, you've given me even more to think about :)
