SOLD!

This piping will give you better throttle response, quicker turbo spool, and a little better breathability at higher RPMs. A Nice setup for those who want to maintain a stock look while getting some performance.

I swapped back my stock USDM downpipe and 3rd cat pipe on last night..and the one less cat on this JDM piping makes a noticable difference. Car feels noticably slower now with the US parts back on!

The '3rd cat pipe' is not found in this unit...just a downpipe with one cat, and an intermediate/rear-center pipe with two sound resonators (as opposed to the single resonator in the USDM pipe)

These pipes are not the same length dimension as stock USDM, so they must be used together. I'd MUCH prefer not to ship if possible.

Asking $200 Pick-up/Meet (Negotiable)
