I think because of the way they are made, sidepipes are the largest contributories to horsepower loss. Some have an 1 7/8" core with a lot of packing. Other have 3" core and little to no packing.

I'll take a 20% loss...still puts me at about 400 hp at the wheels. One of these days, I'll have to do a dyno to see what a Roush 402 SR/TW (bone stock) with standard SPF pipes will pull.
