New Age DE CAT
hi guys can some please give me some advice on a de cat, i have a WRX new age, with a Blitz NUR spec R cat back system, i am looking to de cat the car but don't know what size pipes i need and also how many pipe i need
also looking to upgrade the stock Turbo, mods already done are FMIC Fuel pump Sti Pink injectors thanks guys |
The 02-05 WRX comes with 3 Catalytic Converters. The first is a "pre-cat" which is located in the up-pipe. This piece is between the exhaust manifold and the turbo's hotside. The second is is the downpipe and the third is in the midpipe. A note that many people consider the dowpipe and the midpipe to both be one part (even though they are two pieces on the stock car) and refer to the combined part as the downpipe (which would include two cats). Many if not most aftermarket downpipes replace both the stock downpipe and midpipe.
The 04+ STi and the 06+ WRX do not have a "pre-cat" in the up-pipe. They simply have the cats in the downpipe and midpipe like the earlier WRX. http://www.wrxtuners.com/forums/f51/...els-you-25335/ |
