The pros and cons are hashed out here. Plenty of info. A lot of the power graphs are misleading as the always do it with the full setup.

I've done it both ways and found the exhaust MOD to yield more results than intakes.... unless you're pulling your motor out and strapping on an LTH and an aggressive tune. It's really not gonna make much of a difference. If you're doing standard intake & exhaust MOD? You'll be good my way...

Good luck to you bruh. Over and out.
