My $0 Modification Today :)
I believe the 98's only had one tailpipe.
**Edit** From JRP's faq page
This is some basic info on the LS1 that i've gather from all of the internet and put into one list:
1998
1. Had differnet casting heads which had perimeter bolts and valve covers.
2. Ignition coils were mounted to the valve covers one at a time.
3. The water temp gauge actually works.
4. 98's do have an oil life monitor, they just don't tell you anything when its time for a change. You can find it in Auto-Tap
5. WS6s had single outlet exhaust (all others had duals)
