If they're installed properly and have low mileage then theres nothing wrong with it. If they had any sort of gear whine while installed in the previous car I'd stay away from them.
The Flowtechs are the same as hooker. Dont have to remove them to drop the tranny, only problem is you'd have to use their x-pipe or have one custom fabbed for it, no others will fit it.
If you get it tuned....should be around 250+/290ish. Stock you should be around 220rwhp/275rwtq, so with those mods and the stage 1s with a good tune it shouldnt be too far off...
BTW: the car is a BONE stock m6, w/ removed filter/descreened MAF.
DYNORUN.002 Max POWER= 285.2
Max TORQUE=311.6
and yes it's all SAE.
thats from LS1tech.com :shrug:
Best thing for you is to stop spending money on speed parts and start spending them on suspension parts.
Power is no good if you cant get it to the ground.
LT1s were rated at 285, although they were underrated. However they had several problems like power falling off fast past 5k and I believe floating valves. With some head work and the internals balanced they'll hold off an LS1 easily.
If you're gonna spray why not, its about the same price as the bullit intake and its a little different. The gains are nothing spectalular, but at least its not plastic.
Yup hooker headers allow you to remove the tranny without pulling the LTs...and Flowtech is just a renamed Hooker.....both owned by Holley.... and yes they do make a DOHC version.
