Guest Posted February 25, 2009 Share Posted February 25, 2009 Where are these cheap catted downpipes? I didn't notice them to be any cheaper than few years back... Link to comment Share on other sites More sharing options...
Kylar Posted February 25, 2009 Share Posted February 25, 2009 Probably because it costs $0 and remains stock looking. I actually had a cobb catted dp ready to install in my garage but sold it and then gutted my stock. True that an aftermarket piece will flow more, but not so much more as to make it all that cost effective. You free up most of the power by removing the cat right after the turbo. At that point you can spend $500 on a dp to realize 10-12 more whp if that makes sense. For me I would rather spend $150-250 on a real catless dp, and be able to revert to stock without having to search for a used stock exhaust.

ultimakf7 Posted February 25, 2009 Share Posted February 25, 2009 i'm assuming that the gutted dp will throw codes unless you flash the ecu to stage 2? I had a 3" Perrin DP for 6 mos before getting the AP, w/o an antifouler, and never threw a CEL. Your mileage may vary. Link to comment Share on other sites More sharing options...
Gearboy Posted February 28, 2009 Share Posted February 28, 2009 The 2009 WRX supposedly has "optimized" cats - something like 30% better flow. Would it be possible to use the 2009 WRX DP on a 2008 spec b (or LGT)? Generally the same engine, isn't it? I like the stealth sound of the idea. Or is the 2009 WRX DP bent too differently, etc. to use - anyone know? Link to comment Share on other sites More sharing options...
Guest Posted February 28, 2009 Share Posted February 28, 2009 It should bolt on. Link to comment Share on other sites More sharing options...
Gearboy Posted February 28, 2009 Share Posted February 28, 2009 So VF52 + 2009 WRX DP on a 2008 spec b = kinda-legal 265 HP? Or am I forgetting some differences with the WRX heads, etc? Link to comment Share on other sites More sharing options...
itsme Posted March 1, 2009 Share Posted March 1, 2009 One more thing, does anyone know what kind of gains can be expected from a gutted downpipe stage 2 tune? I've heard that stage 1 alone is a 20-30hp difference, would the gutted DP + stage 2 tune be +40-50hp over stock? I made 277whp with a FMIC and, K&N intake, stg2, and opensource tune on 91 cali pump gas. Hitting 18.5 @2800rpms.

2_point_5_GT Posted September 5, 2012 Share Posted September 5, 2012 I am super late in this thread, but I have an ABP 06 LGT with UEL Headers, a Catless Uppipe, Turbo XS RFL BOV, a Cobb Accessport, and a stock downpipe, I want to gut/bore it out, what do you think about gutting it? I know I can reflash the ECU with the Accessport, but any gains at all? Link to comment Share on other sites More sharing options...

I know I can reflash the ECU with the Accessport, but any gains at all? When I installed my dp it improved my spool and fuel economy. From what I have seen gutted and cattless gives you about the same performance. Before you gut your dp get a spare. You may have to go back to stock one day. I can get you cattless do around $290 shipped.

Why destroy your stock pipe when you can get this for $150 shipped http://www.ebay.com/itm/2005-2009-Subaru-Legacy-GT-2-5L-Turbo-Exhaust-3-Bellmouth-Down-pipe-/180864695187?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a1c603b93&vxp=mtr It will flow better then your stock dp, and this way you can always convert back. Stock DP's are expensive to replace unless you can find a used one. Link to comment Share on other sites More sharing options...
