I used to have Hooker headers on my old GN. Ran 10.70s with them. No complaints as far as street driving. Didn't like the design of the pipe that the turbine housing bolts to, though. Had a tendency to work itself loose over time. I had to add a support bracket to keep things in their place. At...
I currently have my drag radials on a set of Weld Drag Stars but would like to stick them on my stock T wheels for a stealthier look. Has anyone tried it? Any rubbing?
Chances are a shop won't just clear the car. The paint is so thin on these cars the second they sand it to prep it for paint they will blow right through the paint. It will have to be repainted. You get what you pay for when it comes to paint work. Price will vary from shop to shop and on how...
Any and all headers may or may not need modification for installation. Every car is different and every set of headers can be slightly different (regardless who built them) which leads to minor mods required for them to fit. If you don't want to modify something in order to make it fit, your...

I have Turbo Regal Custom Parts headers (Kenne Bell headers basically) as well as their 3" downpipe and a Hooker cat-back. No drone. Very quiet combo. I've been 10s with the Hooker cat-back and the stock headers. Haven't been to the track with the TRCP heads and DP yet.
When I ran my old GN as a dedicated race car, I vented the gate straight down. That said, I have been 10s with the gate routed back into the exhaust. Since my T is a street car, I prefer it quiet so the gate is routed back into the downpipe. I like having a whisper quiet 10 second street car...
I never liked the sound of an open wastegate on a street car. It makes an otherwise quiet turbo car sound obnoxious. Stealth goes right out the window. Plus, since the exhaust coming out of the gate is pre-turbo, it sounds like an open exhaust V6. Not the most appealing sound.
