hey all i have a VT Calais SII with the L67 under the hood. my current mods are.. XU6 memcal, 10PSI boost upgrade and SS inductions growler cold air intake. At this point is it advisable to install the 1:9.1 ratio rockers then a better exhaust system? or exhaust first? if so what would be the best headers or cat back system for her? i don't want it loud as i want to keep it a sleeper. IF any of you have suggestions please tell, thanks :D

Basically Pacemaker extractors > 2.5" Manta Catback with a rear resi on the back I would think. He did mine, not loud on idle and when coasting. Of course if you give it some it'll make noise, not as much as most though

VT Calais L67 (conversion)
do the rockers first man... you will see good gains expecially since its forced induction... maybe even get a remote tune to get even more out of them.

then do exhaust

yeah rockers are the go, just a tad costly but i just got the extractors and high flow cats for it. as for a remote tune were talkin more money so ill keep her tame for now, after all it goes that much better with the boost CAI and chip alone tho if i decide to keep the car ill have a tune done for sure!
