I'm starting to look for exhaust / intake - logbook Toyota Celica 2002

Plans to make a full track from the collector!
There is already a stainless steel pipe, I think it will be enough for 61.
According to the bank, I decided to take a big one, the bale is not very loud and the jasma standard calms me down)))
I don’t want the car to “fart” very much at high.
Can you tell me what other options to look at?
