- Again, an awesome part and high quality! I recommend it!
Reasonable $ for awesome DP
- If you want a catless DP and need the ability to run a wideband AFR then look no further...save the extra 300 you'd spend on a Cobb and definitely don't waste your money on a two piece Perrin DP!!! the O2 bung is long but cut or bend the heat shield...or just don't use it like I don't because it serves little purpose and is more an annoyance than anything else...also make sure you bend the transmission mount bracket.
fit 2011 wrx no issue agency power is pure quality stuff smooth welds inside flanges.
already has bung welded for wide band 02 with a plug . well thought out not just a big name it is a top quality DP. thanks IIR !
AP down pipe
- Agency power is quality no fit issues on 2011 wrx . Spool is way faster money well spent!
Good DP for the money
- Very impressive piece for the $$. Mounts to turbo and stock CBE flawlessly. The stock CBE on my 10 WRX Sedan has a 3" flange that tapers to 2.5" when internal donut gasket is removed. While the mounting bracket fits fine it is very close to the trans crossmember. I decided to trim a bit to prevent rattling. Also, the heat shield that mounts to the underside of the car must be removed or trimmed to fit the O2 sensor because of the elongated mounting tube. Because of these minor issues its a 4 out of 5.
