I'm going to get a new downpipe and cat for the car before I install/tune the Hondata. Is 3" too big for a stock Greddy kit at 7psi? Or should I stick with 2.5"? My exhaust is 2.25" for now (OEM ITR exhaust). No other mods to the car, and nothing really planned in the near future.

 

Every one around here seems to like 3 inch stuff, i guess thats the way to go

hmm anyone else? Is it possible to go too big with this?

 

can you have a custom 3" downpipe made and still retain ac?

 

No 3" will not allow AC.

 

I will continue to use the cast iron pipe off the compressor so I can retain AC, but the downpipe that bolts to that can be changed.
