silverone Posted March 27, 2012 Share Posted March 27, 2012 Hi everyone I talked to a flowmaster tech. yesterday and I was asking about a high flow cat. What he said surprised me, he said our factory cats are high flow. And if their not bad ,pie throwing a cel code, its a waste of money to replace them. I don't want my subie sounding like a (fast and fury ricer), so he recommended a flowmaster 12414310 muffler for a nice deep subie rumble. He said Id see 10-40% increase in flow with this muffler over oem. He also said to start off by leaving the rear resonator on , then if i want it louder, I could take it out later and not affect my engine management system. Or set CELls. Any thoughts on this?

TbirdMan Posted March 27, 2012 Share Posted March 27, 2012 As someone who has a Magnaflow that the last owner put on that has a deep note, i wouldn't suggest it. The droning is actually pretty annoying , especially from the back seat. Link to comment Share on other sites More sharing options...

TbirdMan Posted March 27, 2012 Share Posted March 27, 2012 No the muffler. Also, without unequal length headers you won't actually get the "boxer rumble". You get a slight rumble, but not like a wrx. Link to comment Share on other sites More sharing options...

silverone Posted March 28, 2012 Author Share Posted March 28, 2012 What about the ones on e-bay for $209 ? Btw I always thought the point to headers was to have equal lengths. Link to comment Share on other sites More sharing options...

The "boxer rumble" people are obsessed with, is the sound of inefficiency.

FUIAAE Posted March 28, 2012 Share Posted March 28, 2012 I'm actually looking for exhaust information for the EG33 I'm dropping in to my sedan. I'm interested in mufflers and such, I want a straight through baffle but they're supposedly going to be stupid loud. And I've been told the EG33 is the loudest engine subaru has ever designed due to the VE% of the engine >98% at WOT. I want to hear it scream when I punch it but don't want to drone. Suggestions?

But when I do slam it to the floor I wanna hear it growl. I'm thinking of getting a straight baffle muffler with a U-pipe, supposedly they still sound aggressive but aren't really loud under normal load.

Id like to see what it looks like. with brand names and part #'s would be nice. or does that have to be a custom build ? Link to comment Share on other sites More sharing options...
FUIAAE Posted March 29, 2012 Share Posted March 29, 2012 You can find them on jegs, summitracing and ebay. I'm thinking of going with an ebay U-pipe muffler. I bought a Delkavic muffler for my bike from ebay and it sounds great so I'll risk buying there again. Picture coming. *edit* The return pipe supposedly cuts down on the rasp and eliminates drone... until you open it up. http://i.ebayimg.com/t/HIGH-FLOW-TWIN-LOOP-SPORT-RACING-DESIGN-MUFFLER-EXHAUST-3-5-OUTLET-KIT-/00/s/NzgwWDc4MA==/$%28KGrHqFHJ%21sE9ur6ZlnLBPc1hBo90Q~~60_58.JPG If you want the ebay link I'll post it.

TbirdMan Posted March 30, 2012 Share Posted March 30, 2012 honestly, you probably couldn't measure the difference in efficiency between equal length and unequal. if you were building an all out race car like the WRC cars, you might look at equal length to squeeze that last bit of power out of it (listen for the difference in sound between the 90's era impreza WRC's and the newer ones, they switched about 1999-2000 IIRC), but for everyday, UEL is fine.

It's the same length, it's just canister design. And it'll be going under the kick panels not under the rear. Keep in mind I'm a BH or BE chassis, not the newer legacy's. "01" sedan.

subikid90 Posted March 30, 2012 Share Posted March 30, 2012 I was talking about the diameter of the whole thing. In a BE there is much more room than a BD, so you will be fine most likely. -Subikid90 1997 Legacy GT 5spd & EJ251 w/EJ25D heads ~10.5CR 1998 Legacy GT Limited waiting for EJ22T hybrid swap Link to comment Share on other sites More sharing options...
