i posted this over in LS1tech but maybe i'll get a little more replies here.

just wondering if anyone with a cammed or H/C LT1 running ORY to cutout and then through a stock muffler? any major detriments to performance other than hp like it messing with AFR or tuning issues? also if you have any sound clips post em up, thanks!

 

i responded on ls1tech

 

auto lt1, cc 306, LT's, cutout, stock catback, no problems and acceptable sound.

 

i have that setup with pacesetter LT's, ORY, cutout and factory catback. sounds great

 

Here you go...just for you
When the video gets done optimizing that is...

My 401 starting closed then going open...Open cutout was still threw a 5 inch bullet muffler....

Almost forgot.....I have a wide band installed and my AFR changes changes only .1-.2 of a point win the cutout is open...So, very little difference on my combo...

 

cutout closed, pacesetter LT's, ORY, stock catback...illl have to post one with it open another time, cant seem to find the file

 

hotcam, shorties, ypipe, gutted cats, factory catback going through cut-out. Sounds nice but it would sound alot better, going through some nice tips rather than going through cut out. Get borla intercooler tips, cut off muffler, and call it a day.
