Let's talk a little 'bout horsepower

[dpantazis]

i think everyone is neglecting the extra 5-10hp that you get when you put the MBRP sticker in your back window. are we double counting it?

really thought, i think that this is good to show how one variable changed causes and effect.

There was a write up about a similar topic in the latest diesel power magazine. The article compared stock exhaust vs. cat back vs. turbo back. The test was on a 03 Duramax and the results were as follows:

Stock Exhaust 257hp 425lb-ft
Cat Back 264hp 443lb-ft
Turbo back 270hp 452lb-ft

The article also said that although the turbo back system made more hp and torque, the cat back exhaust seemed to have better mid range power.-popcorn
