I just added a test pipe to my stock exhaust system and my friend told me that if i take of the muffler and let the car run with out the muffler it would make more HP than having a stock exhaust with a test pipe.

so my question is which is better in terms of HP and torque

Stock exhaust with test pipe -

Stock exhaust with test pipe and no muffler -

or the way i used to have it which is having the exhaust come out of the exhaust manifold downpipe with out connecting to the rest of the exhaust system
