Flowmasters

I currently am running the 70 series dual exit on my 03 5.3 tahoe. i was wanting the sound to be a little louder. i saw that the 50 series delta flow on the flowmaster website had about the same interior noise level as that of the 70 series. If i decide to go to the 50 series delta flow will i lose any low-end power?gain any?? anyone running a 50 series delta flow??? Any advice or input would be greatly appreciated!

or would i be better off going to a magnaflow?? If so which one??

I would love to hear someone's opinion on 70 series versus 50 series deltas as well.

The more free-flowing the muffler is, then the less back pressure you would have. These Vortech engines make their low-end power with back pressure, but they gain high RPM power when the back pressure is removed.

 

Going from a 70 series to a 50 series probably shouldn't give a real "seat of the pants" loss. I think it would only be most likely noticable when towing.

How about if you make the back end less restrictive..... say oh...... A magnaflow on the back end but you put a UPD (NSV) intake on the front end? Would you then gain your low end tourqe back?
