First mod I'd like to attack will be headers, so here are the questions...

Will Stainless Works Headers/Cats bolt up to the stock exhaust?
I want to keep the nice "quiet" stock exhaust.

I'm pretty good with a wrench, but is header install a one man job?

I thought I read somewhere that there are 2 different size resonator internal ID's.

Which years had the larger internal ID?

Mark's chip is also in the plan, but the top end porting will have to wait until next year. Maybe by that time I'll have saved enough for a 415...

Enough questions for now.
