Finally got my HKS catback installed. I went with Berks resonated test pipes also.
I followed alot of the diy here and install wasnt too bad, yes a couple of the bolts/nuts holding the cats on were a pain.
PB Blaster , patience and taking the front wheels off helped alot
I chose the HKS cbe, because i didnt want alot of drone and wanted it quieter until i get in the throttle.
Under 3.5-4k it is pretty quiet, when you get into it it does open up , alot better than stock!!
Car feels more responsive , with the Berks test pipes there is nothing choking down the exhaust.
It might be mental, but with intakes and full exhaust done now, the car seems alot less restricted, it just goes.
