for those of you who have recently read the DH pulley thread, cdmx stated that after he put his silencer in he noticed better performance. would it be safe to say that a I/H with stock piping and cat with a muffler, or perhaps just a I/H alone would yeild better results than a I/H/catback would?

well it would depend on the size of the piping

2.25 seems to be the best so far

or is there a way that I could use a stock muffler from a car higher in the food chain would that work also?

I was thinking like an RSX muffler or perhaps an SI (99-03) muffler

We dont honestly know unless we had a dnyo in our garage, but yes its a good noticable difference in torque
