Default is 2.5" piping too much

You can run 2.5 without an issue on a 1.8, will you be keeping the cats?

our stock cat pipe is already 2.5 inches, the only thing that need replacing for the complete exhaust would be a header and the cat back portion. everytime i head down the shore i always pass this really nice lookin exhaust shop so ima check them out and see what they can do. do want it to be welded, clamped, or flanged?

you do that. probably clamped. and as far as headers go.. i been keeping an eye on my corolla friends and a company is making headers for the corollas (2009 nd up / 2zr engine as well) and are going to do a before and after dyno after its done. so ima wait for that first.

Looking at the 1zz-fe header they have. Now that looks like a proper header. Are the corolla people doing a group buy? If so I need to get in on it!
