Are there any underdrive pulleys?
What about shorty equal length headers?

Would these type of mods be good or bad?

Thanks

As far as I know, neither exist. But, they'd both most likely be bad. The pullies would stress your accessories, and the headers would increase hp, but you'd never get off the line due to loss of tq.
 






Thanks

I guess that I need to find the cat back system and also the intake system's out there.

Another question, with the cat back systems, are they a system the "home tree" mechanic can do, or is it to be done by a shop?
Thanks
Guy
 






Depends on if they're bolt on or weld on systems. I'd personally always like a welded exhaust to guard against leaks. Your best option is usually to get a local place custom do it for you. Pick the muffler, and get a custom 2.5" tailpipe.
