downpipe

[steviewoods]

hey guys i was wondering how much it will cost for a downpipe and if it will add hp to the mazda3 or if it is even worth it .....thanks...

no, it won't add anything to your mazda 3 because you won't even be able to install it. a downpipe could only be used on a turbo car.

what you could do is get headers, high-flow cat and a cat-back - this would add some hp to ur car.
