when running a gt3076 and making about 400whp how much power will be lost when you recirculate the the dumptube backinto the downpipe.

i know open dump tubes are louder and also makes the exhaust as a whole bigger and louder.

my question is how much power will be lost without a not recirculated dump tube.
its its only a few hp then i say its worth it just to make it quiter when the wg opens, but i heard on high boost high power cars (gt3076 or gt35r) that you can loost a lot of power 30whpp++ with a recirculation dumptube

 

bump for answers

 

As long as it is routed with the right angle back into the exhaust then it will not loss any power. Just cant plumb it back at a 90 degreee angle.

 

I personally prefer when it is plumed back in. Open dump is way too loud

 

Open dump FTW!
