I have a 1997 z24 and was wondering what size tubing should i get for a cat back. Also i have heard that 2.5in tubing actualy gives u less power in low rpms is that true????? and what size tubing should i get for a cat back?????
well if you get 2.5" you do lose a little in the lower end but it moves your power band into the higher rpms where you will gain power. sence you have a 2.4 then I would go with a 2.5" but no bigger unless you are going to have forced induction. if I were you I would go to the top of the page into the faq post and read that then do some searching, there a million and one post about it and there is enough info on it to keep you reading all day.
good luck.
