I was wondering where the best place 4 a cutout 4 the exhaust I have JBA short headers then it comes 2 a Y then the muffler is it better closer 2 the cats or closer 2 the muffler

 

The closer 2 the cats the better. Or even before the cats but you might need O2 sims for this so you don't set a check engine code.

 

does the cutout mod work i mean is it worth it

 

Yeah it's worth it. Go for it dude.

 

I've been thinking about this too but what about backpressure? Do you lose any low end torque with the cutouts open? Basically, are there any negative side effects?

 

Idont know about backprsure I run a s/c if that makes any diffrence

 

you will lose backpressure (and therefore torque) but it should be made up for at the end of the run up high.

if you want try this:
using a Quicktime Electric Cutout, have the cutout closed, after you launch off the line then open the cutout. in theory this should give you the best of both worlds. somebody correct me if i'm wrong or this won't work....

 

I have tried it open and it felt good on the take off put it felt week on top end put thats before s/c I herd open gives more tourqe 4 the take off put i mite be wrong

 

Look at Fbody dyno charts with and without cutouts open. Power / torque is up all across the rpm range. Look up a post 10 months ago by Redhawk and look at his dynos on his 6.0 truck. The chart will show a large increase in power and torque all across the rpm range.

You wont lose torque.

 

well thats good to know <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> i was told wrong
