exhaust what size recommened

[CMF_underground_micra]

heya all agian i am in the process of making my own exhaust and was wondering 2.5 or 3 inch exhust i am going to be fitting it straight thro with only 1 high flow cat and a cannon 2.5 in with 5inch out i an weld the exhaust and get all the bending done ......... just courius on flow between the 2 i am also making a plate to the manifold to remove the cat converter there so the only 1 will down under the body i am thinking also of running 2 cannon's out the back1 on either side as i looked there and seen plenty of room to do it

Way overkill for a 1.3lt engine! For NA applications stick with 2", turbo use 2.5".

deffinately 2inch

2'' to 2 1/4 at max. THat is what mine is. With a 4 inch cannon out the back fills the little slot real well. Dont go any bigger the 2 1/4 inch or you will go backwards int he struggle for power

so 2 1/4 max ....... mmmmmm i think i can find pipe that size at the back i am ganna do a y piece to each of the cannon's at the back should look good from the back seeing 2 cannons 1 either side

definately 2'' imo, 2.5' for mild turbo and 3'' for pshyco turbo conversion.

2" ftw and i reckon 3" black tip on muffler is the way to go, not cannons. i always wanted an is200 muffler and tip on my car. i reckon they look so nice.
