High Flow Downpipe – P2 S60 V70 Turbo FWD
A down pipe upgrade will significantly reduce back pressure, allowing the engine to breathe easier and thus provide much improved throttle response, torque production and good old HP. The exhaust tone is slightly different (throatier), but not really louder.
Our downpipes utilize a ceramic 3-way catalytic converter. Also, an integrated flex-joint helps to eliminate stress cracking and vibration. 3” mandrel bent stainless steel is used from inlet to outlet for highest flow capacity and long life.
The oxygen sensor ports are retained as well as factory mounting points and connections. Our pipes also include attachment points for the heat shield, an ipd The Volvo Specialists exclusive. Also included are new gaskets and it’s compatible with the stock exhaust as well as most aftermarket systems.High Flow Downpipe
2017-03-12 – “DT” from VIRGINIA BEACH VA
It took 7 days for standard mail to deliver, which was good considering west to east coast. It installed on my 2001 V70 Heico HS7 nicely. It would have take lesser time if not for the rusty flange bolts….i’m thinking 2 hours top. I had to stretch/pull the O2 a wee bit to connect to the Catalytic converter. Its not loud (more throatier “if you will”) but for the first time I could hear the turbo. I noticed my PSI dropped (on IPD Vaccum/Boost gauge) from 9psi to about 7psi. However, when I stepped on the gas, it was a quicker response and noticed it hit 6000 rpm for the 1 st time. It might be due to HP might be more continuous through out the boost…but only a Dyno would reveal such a thought. I”m pleased.
