i have a 99 WS6 with the following mods:

FLP Longtubes
Corsa Catback
Catted Y Pipe

K&N Cold Air

LS6 Intake Manifold

Thunder Racing Custom Camshaft (230/232 .595"/.595" Lift on 114 LSA)
Valvetrain supporting mods
Stock 853 Casting Heads

NOS Wet Plate kit used rarely (50 shot)


The questions i have are:

1) What sound change can i expect if i swap my catted y pipe for an off road y with my corsa exhaust and longtubes/cam?

2) For my mods, would i see any noticeable gain switching to a FAST intake/TB combo or other brand aftermarket intake manifold?

3) If i decide to further improve upon my N/A power, what would be a good set of heads to match to my combo?

thanks in advance!!

Mike

Anyone have any suggestions?

1) Yes your exhuast will be raspy.
2) Yes you will see gain on the fast swap.
3) A set of ported 243 heads would be good imo.
