Recommended shop for headers install & lip/valance install?

[Osiris_x11]

I need the following jobs done on my NSX in the near future...

- install aftermarket headers/exhaust-manifolds
- re-attach portion of aftermarket front lip to lower-bumper
- swap '91-'01 rear valance for '02-'05 rear valance & paint-match Berlina black
- inspect/adjust suspension
- dyno/tuning

Any recommendations for clean/uncompromised & reasonably priced service at local area shoppes in Greater Austin TX?

Thanks!
