| Aaron's 2004 WRX: Invidia Up/Downpipe |
|
![]() |
| The Invidia up/downpipe combination is a great addition to my Subaru. At first glance both pipes appear to be very well made- cleanly welded, with thick flanges and heavy duty hardware. Running the bellmouth downpipe allowed me to bypass both of the stock downpipe converters, gaining me those extra horses. The fitment was perfect into my stock turbocharger and the unit bolted up exactly to my Borla Hush catback exhaust with the 3” flange adapter. |
| My first observation of the Invidia uppipe is that it is much lighter than the stock unit, which never hurts. Of course the Invidia pipe is catless as well which allows the exhaust gasses to flow smoother and the turbo to spool quicker. I had no fitment issues with the uppipe; it bolted right up to the exhaust manifold and turbo just fine (of course I made sure to replace all the gaskets). |
