I got a 2.5 inch exhaust n it runs fine. yeah u get a little lack of back pressure but throw on some headers n maybe advance ur timing a tooth or two. And mandrel bending Is always better cuz its one solid piping just bent witch is smooth for the pressure n exhaust smoke to go through.every cut n weld n crease in the piping with fck with the pass through of the back pressure
 
The only thing it would be bad for is everyone on this planet's ears b/c it will sound like shit and annoy everyone. Please use a muffler. If you lose 1hp, its ok.

Mandrel bending is when a type of insert is used in the pipe to limit wrinkling and maintain even ID during the bending process. In crush bending, the metal wrinkles and the ID of the piping is reduced.
