i doubt you will get 40, nevermind 50

I think the RSX-S was doing around 170-175whp - with I/E/RH + flash it was doing around 205-210 i believe.. i can't reember exactly - with the kpro it was getting 210-215 (something like that) -

I'm getting DC headers and exhaust for 650, but that's only because my uncle has friends in DC.

If you think I/H/E is expensive, you should see how much TC's, SC's, complete sound systems, and other parts for your car costs!

it depends on the person. To some people, spending 1000-1500 in car audio is more valuable to them than a I/H/E setup.

The term itself is actually kind of funny because technically most modifications you make to any car are "bolt ons" regardless of how much work goes into it but when you hear the term you think of the obvious i/e/h

the only non-bolton's are porting/polishing, engine blueprinting, etc...lol

but i do consider custom work even if it involves bolts, to not be a bolt-on since you have to fabricate it yourself.
