Intake manifold and exhaust questions 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!!

2. You should see some gains but nothing crazy gains. You could look to gain about 15 hp with an intake manifold setup.
3. Trick flows, all pro or AFRs are always good. I would get a hold of them. They would be able to get you headed in the right direction about head choice.
