couldnt u loose power if there is not enough back pressure

 

changing the muffler and tailpipe couldnt effect the backpressure enough to make a difference...with the pressure created by the exhaust manifold and todays catalytic convertors, changing the back section coudlnt do much..

 

You must not have read it the way i meant it.

Drop it

 

Or maybe u wrote it in a way that was unclear to other people and i was just trying to clear things up for those who may have not understood...but ok...its dropped...

 

ok my turndown is a three inch pipe about a foot and a half long (that's it). Thats all that I have done. It may be all in my mind but if it's not I would like a suggestion. The whole backpressure thing confuses me, if you lose backpressure you lose power and if you have too much you lose power right? The only other mod is the drop in K&N filter.

 

but the CAT and the rest of the system should create more than enough back pressure...look at the fact that people are putting free-er flowing headers and CATS on the hemis...and gaining performance...so just the backpressure that you lifted shouldnt hurt...

 

it was clear








i dont think you really lose power with less back pressure it juss moves your power band up

 

Now that makes sense. V8's are not known to need much if any backpressure, it has primarily been a small engine thing.

 

so if my power band moves up I lose low-end torque right?

 

Yep, pretty much. It will move your torque curve up with the horsepower curve, not to mention their peaks.
