Installed lt's got ??? hey i just installed some kooks lt's with the catted Y on my car and it feels like i lost a good bit of low end torque...i got a m6 car with 4.10's and i got the catted Y cause i got the loudmouth and without cats its just to raspy and its kinda raspy now from 4500 rpms on up but below that is sounds great..my question is how can i get some of that torque back without putting heads on my car??? thanks for any help

Well first off, I would have ditched the cats and put on a catback like Hooker or go with true duals. That would show the benefits of longtubes better and sound better too IMO. You will probably need a tune now. Your O2 sensors are now further back which is going to affect AF mixture. I would install an LS6 intake (if you don't have one already) next. If you do have one, a cam would be next. I personally wouldn't do heads without doing a cam.

I think the 3" header collector is pushing the torque curve up the scale, which isn't a good idea on a street car. Maybe Stainless Works has the right idea with their headers, they seem to be the only company pushing 2 1/2" collectors.
