FIT turbo exhaust size discussion:

Got the go ahead from the wife to turbo the FIT. What I need to know it what size exhaust to get. The engine is a small 1.5 and has 109 Hp, much like the d16a6(CRX SI)....the turbo with the HKS kit is a t25. I might be looking to up the boost from the stock 5.7 to MAYBE 8 or 9...Thanks for all your input guys.....................!

here is a link for the kit if it helps: http://www.thmotorsports.com/hks/hks.../i-218310.aspx

 

anyone?

 

2.50 all the way back . straight pipe

 

why would you run a straight pipe 2.5" exhaust on a fit that his wife drives.

it will be loud as hell and drive people crazy. also this thing will not make enough to out flow 2.25 with a t25 kit.

 

wife driver, fit, drive people crazy....exactly why i say.
whats the point in haven a turbo if you gonna go slow and put baby stuff on it?
just get a cam for it or something usefull
and straight piping all the way back from a turbo isnt that loud

 

What are the HP limits of a 2.25...what about a 2.5?

 

depends on alot of stuff. go with 2.5 its not that big and its alot better then 2.25. i jus went to 2.5 from 2.25 and eez nice

 

It's not all about maxing out the flow of a particular size tube. Less backpressure is better for this setup. It's not hard to make a 2.5" exhaust that is quiet either. Put a couple small mufflers up front and a big one in the back and it should sound great and still be quiet.

 

I was thinking the same thing. Quite but still powerful.

 

You won't need multiple mufflers, all you need is a properly sized resonater, and good muffler, no N1 style crap.

 

Looks like most people say 2.5 inch....sounds good to me!
