Legasee Posted July 16, 2006 Share Posted July 16, 2006 I've searched and can't find any information on who's tried mating an aftermarket downpipe with the OEM catback. I'm itching to go COBB stage 2 and might end up going OEM catback since the there's not much power loss with the OEM, plus it's gonna be "free" and nice and quiet. Any leads or information appreciated In Taiwan now... Link to comment Share on other sites More sharing options...

hal9e3 Posted July 16, 2006 Share Posted July 16, 2006 Cobb DP w/ HFC, OEM CBE, no issues. I think the issues will start when you start doing a mix-n-match system. Link to comment Share on other sites More sharing options...

Are you running AP too?...I'll do a HFC if i can afford it...but for AP owners, COBB recommends catless dp for max hp increase, right?...or is their dp with HFC good just as good? In Taiwan now...

Mines Posted July 16, 2006 Share Posted July 16, 2006 go with hfc, at stage 2 level, you wont see a world of a difference Link to comment Share on other sites More sharing options...
colatkitty Posted July 16, 2006 Share Posted July 16, 2006 Both Cobb and PDE dp's taper down to stock diameter at the end, and retain the stock donut washer, so they will bolt right up to your stock catback with no problems Now hurry up and get it done already Link to comment Share on other sites More sharing options...
hal9e3 Posted July 16, 2006 Share Posted July 16, 2006 go with hfc, at stage 2 level, you wont see a world of a difference +1, if you go catless UP the DP's HFC will be the only one left, IIRC. WRT Cobb's recommendations, stage 2 is actually TBE, with DP being the minimum requirement. Link to comment Share on other sites More sharing options...

SC GT Posted July 16, 2006 Share Posted July 16, 2006 ...what do you mean?...just about everyone has this set-up? (aftermarket downpipe with OEM catback?) Yes. Aftermarket CBEs for the LGT are overpriced, so most have this set up, or at most (like me), just mufflers. Link to comment Share on other sites More sharing options...

colatkitty Posted July 17, 2006 Share Posted July 17, 2006 ladies and gentlemen....this guys here ^^ is the one that got me all thinkin about the AP at our last mini meet(...and then he shows us his prestine condition S2000.. but that's besides the point )...tells me all this difference in power, got me all thinking about my stage 2 when I had my WRX... what u running again for dp colakitty? Thanks for giving me all the credit for giving you the stage 2 bug You will not regret it after you get it all done. As for my DP, I got the bug WAY WAY before any DP was made for the Legacy, and before the AP or Ecutek was available for our cars. I got a used PDE wrx downpipe from NASIOC and had a muffler shop extend it to fit my car... fits and works great btw. Even without any EM done, the DP made a huge seat of the pants difference on my car. Lag was reduced noticeably and throttle response is increased as well. Best $200 I have ever spent on the car.

TSiWRX Posted July 17, 2006 Share Posted July 17, 2006 ???? Isn't that just about everyone? ^ +1 The vast majority of LGTers at "Stage II" utilize the aftermarket DP (either full length or shorty, and of various incorporation of catalyst/cat-less setups) paired with OEM cat-back section combo. It should be noted, however, that while the Cobb Tuning Legacy AccessPORT FAQ cites the above as a "safe" and desireable (for best boost-control) combination to run for their various off-the-shelf "Stage II" maps, this combo remains non-optimized for Cobb's off-the-shelf maps, which can only be achieved with a fully catless turbo-back. Christian from Cobb has also been noted to recommend that off-the-shelf "Stage II" map owners incorporate at least the use of an aftermarket HFC third-section if they pair their off-the-shelf maps with a "shorty" DP, and in addition to true system/map optimization, the only way to achieve best-"safety" with their off-the-shelf "Stage II" maps is with the use of a fully catless turbo-back setup. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...

I feel that I'm going in circles looking for a very quiet aftermarket catback when this whole time, my need is probably the OEM catback (I had an Invidia dp on my previous WRX and the volume was nice with just the OEM catback when I was converting it back to stock to sell the car. But when I had a "pretty quiet" Espelir catback on it with the Invidia, it was so loud, thank god it came with a silencer, but the silencer robbed the power...so I've come to accept cake and eating part ) I think hearing the MR catback with OEM up and dp will finalize my decision ....dibs on first person selling their USED MR catback! (ya'll.....thanks for all your inputs and suggestions...always greatly appreciated ) In Taiwan now... Link to comment Share on other sites More sharing options...
