You can expect mid to upper 3s. 400 is a stretch. I thought you had cams for some reason.

As far as exhaust, most issues with exhaust are related to poorly tuned cars. If the cars run lean the exhaust will crack. No question about it. The higher the EGT the harder it is for the welds and metal to cope with it. The end result is cracking. Some designs are better than others. In the end if the car is tuned properly then you will not have an issue. My exhaust has been on my 930 since before I owned it. I sold it to the customer before I bought the car and that was 6-7 years ago. It was used as a daily driver in Fl so it was pounded daily.

Studs, well you will need to take your time. I can recommend a spray that works miracles. It will help. But that is no rush job. In fact I would spray and heat a week before I was going to remove them.

Lag times will drop apx 800RPM with the headers alone. The turbo will drop spool times a second a half from 2 to 6K RPM.

HP is nice but the drivability should be the goal
