bulwnkl Posted January 10, 2012 Share Posted January 10, 2012 Call me a heretic if you wish, but I've never cared for what many describe as the Subaru 'rumble' engine sound. It just sounds like a fairly serious misfire to me. My turbo Baja (EJ-255) has a crack in the exhaust anyway, and I know that an equal-length header system (truly equal-length, not the nearly-equal-length that many sell to retain the boxer misfire sound) will eliminate the misfire sound. I'm looking for your experience with the most cost-effective (call it cheap if you prefer; I often do ) equal-length header system for the turbo EJ-255. Thanks for any/all help!

Fairtax4me Posted January 10, 2012 Share Posted January 10, 2012 On the right track with the equal length header. Sometimes you can find them for sale in forum classified sections. Check some of the performance Subaru places like RS25 or NASIOC. Might have some luck at Subaruoutback.org as well. Another option is Ebay, http://www.ebay.com/itm/SUBARU-STI-WRX-LEGACY-02-06-Equal-Length-EL-JDM-Exhaust-Manifold-Header-03-04-05-/330667221413?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item4cfd4d61a5#ht_4247wt_836 Quote Link to comment Share on other sites More sharing options...
bulwnkl Posted January 10, 2012 Author Share Posted January 10, 2012 Wow! I've never seen a Subie header shaped like that! All the equal-length ones I've seen before just kinda wrap the right-side pipes around themselves for a while to achieve equal length. Thanks!

MilesFox Posted January 10, 2012 Share Posted January 10, 2012 repair the exhaust pipe or the gasket. that is what gives tyou that 1 cyl lawnmower sound. If you put an equal lenght header on and blew a gasket, it would sound the same. make sure to use new exhaust studs! Quote Link to comment Share on other sites More sharing options...
AWDfreak Posted January 10, 2012 Share Posted January 10, 2012 misfire indeed Quote Link to comment Share on other sites More sharing options...
bulwnkl Posted January 10, 2012 Author Share Posted January 10, 2012 (edited) repair the exhaust pipe or the gasket. that is what gives tyou that 1 cyl lawnmower sound. If you put an equal lenght header on and blew a gasket, it would sound the same. make sure to use new exhaust studs! No, no. It's not a hole causing the sound. That's how 4-cylinder Subies sound because of the unequal-length exhaust lead pipes (and siamesed exhaust ports on some heads) (yes, I have lots of experience with holed exhaust manifolds). I was just thinking of eliminating the misfire sound I dislike anyway, whilst I fix another issue.

bulwnkl Posted January 11, 2012 Author Share Posted January 11, 2012 I have a Honda; a CBR600. It's a great bike! The Baja is as close to perfect as it gets for me for a general-purpose vehicle. I really, really like it and have no plans to get rid of it. I didn't buy it for an exhaust sound. Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted January 12, 2012 Share Posted January 12, 2012 Stone the heretic! (Or make him buy the equal length headers) Dave Quote Link to comment Share on other sites More sharing options...
Leeroy Posted January 13, 2012 Share Posted January 13, 2012 Stone the heretic! (Or make him buy the equal length headers) Dave That is funny! Seriously it does not sound like a misfire (as you put it) to most of us - simply the sound of a flat four! And there ain't nothing finer Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 13, 2012 Share Posted January 13, 2012 Subaru just screwbarued with the exhaust on the later models to make them sound that way. Both of my Legacy's sound like regular ol' 4 bangers. Nothing like the MY 00+ cars that I've driven. Quote Link to comment Share on other sites More sharing options...
bulwnkl Posted January 13, 2012 Author Share Posted January 13, 2012 I don't remember our BRAT sounding like this, either, but then again that was quite a long time ago now. CNY_Dave, that's funny! Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted January 13, 2012 Share Posted January 13, 2012 it's like buying a Harley and working to get rid of the potato-potato-potato-potato sound. CRAZY TALK!!! Quote Link to comment Share on other sites More sharing options...
