Wow, there was another 5 inch DP somewhere else.
I don't think there was much gain versus the 3.5 or 4 inch, but definitely a plus to be able to pass emissions and get substantial gains.
that would be CP-E big boi dp.

ur an xi, u got cat's on ur midpipe -
get'n hiflow cats on ur DP maybe more work
than u may want to do.
performance wise u may gain very little.

i say cut ur cats on the midpipe
or fabricate straight pipe for mid section
- so when u need to get inspection
u can slap on the cat'd mid section.
should gain atleast 10-15whp with 2ndary cats gone.
