RWHP Difference with exhaust??? I would really appreciate some opinions here.
What RWHP difference exhaust open vs. exhaust closed...
LS1 FBody
383 stroker
All of the goodies as far as bolt ons
somewhat small cam (230/235ish)
Dynoed with exhaust cutouts closed (didn't plan on dynoing that day)
Exhaust closed consists of...
headers into
2 cats into
1 "spiral" muffler (very restrictive design) into
STOCK Muffler
Basically this exhaust system is as quiet as stock and with the extra muffler, I would guess just about as restrictive.
Exhaust open is...
Headers into 2 cutouts (basically open headers)
What kind of RWHP gain would you guys expect from having opened teh exhaust?
And just a side note, yes, it is a great sleeper with the cutouts closed. Sounds stock.
