Catless Dp
so i was talkin with a couple of my buddies one drives a 03 cobra another drives a crx we were on the discussion of cat or catless downpipes would it help or hurt me to get a catless. do we even need anykind of backpressure or no bc if we do i was gonna get a highflow cat instead of catless. by the way mine is an 06 supercharged sry still kinda new to this ****

i have a catless and straight pipe and honestly it was cool at first and no you dont need back pressure but it was cool and all at first but now that ***** getting annoying with the sound and my turbo is small and had HELLA sound coming out but your supercharger wont limit the sounds from the exhaust so for you it will be ridiculous.
i wouldnt ever pull anyone over for their exhaust no matter the law but thats just me.

as far as catted vs. catless, without a cat will give minimal gains over a hi flow, imo i don't think the raspy sound justifies the 2-3 extra hp.

don't want to get into a whole big thing, but engines don't need backpressure... backpressure kills performance and is one of the reasons why you would go with an aftermarket exhaust, though majority of people don't know that. that's why it's important to get a properly sized exhaust.

im catless, i dont know if it adds any power over a high flow, but at least i dont have a cat to clog up. it will change the exhaust tone and if you dont get the code deleted you will get a p0420.
