I gained 20rwhp with a lid and catback.
I was suprised to say the least, but it also could have been because I dynoed a fairly new motor (3K miles) installed the catback and filter and about 4K miles later it put down 20 extra rwhp....so it could of been the mods, or just the motor full breaking in

Most of the time they say that you'll gain around 20 rwhp with a lid and catback. Some people think you can get that from just a free-flowing catback, but not often.
