Turbo XS exhaust/DP
« on: July 26, 2014, 09:01:14 AM »
I'm looking to make the jump to stage 2 on my 9-2x and while I love the sound of Cobb, there are a couple things I don't like.  Exhaust only flows as well as the smallest diameter allows and the price.  I do want to find something with a similar sound though.

I've been looking into the Turbo XS DP because it has a removable section that can go catless for the track and catted for the street.  Anyone have any experience with this?
I've also been looking at their CBE with standard muffler.  Does anyone know how this sounds?  I know their quality is great, but I'm having a hard time finding sound clips of this exhaust catted.

I will be running this with a GS uppipe and OEM header with x-pipe.

No one has any experience with any of these parts?

I had a Turbo XS Down pipe,  custom midpipe and a fart can on my red WRX when I bought it.   It sounded very honda-ish with the EL headers.  After a couple months, I reacquired my Cobb Axleback and swapped that on,  and it sounded pretty damn good for EL Headers

Definitely not looking for fart can sound.

It was more from his headers than anything else.

Going from a catted to a catless DP requires a retune due to the flow changes.  I suppose if you had a tune for the DP each way, you could just swap it when you swapped the section in and out.  Also, every time that you swap out exhaust parts, you have to replace the gaskets on that section.  Sounds gimmicky.

My Baja Turbo had a TurboXS DP on it, just the standard catless bellmouth, to a full 3" stainless system, ending in a prodrive muffler.  It sounded deep and more mellow than the similar system on my current wagon, but tipped in a classic 'fart can' style exhaust.

Yes I understand about the tune side of it. Not too serious about it, but seems like a fair option if I decide to race more. Though honestly, I don't understand why so many people make such a big deal about cats being sooooo restrictive. Subaru rally cars use them after all. I'd love to find a Prodrive cat back. Love that sound and wish they still made it. Honestly I'd go for Maddad if it wasn't so expensive. I'm really leaning toward the TXS regular muffler right now. Should be fairly close to the sound I'm looking for. I think.....

Agreed that cats are definitely not what they used to be.  The rally cars have performance cats, but realistically if the turbos are fried every event (or sometimes even more frequently), the cat material is long gone too.   :mrgreen:  Ultimately there's not a huge difference in sound between 3" systems.  The biggest difference is either the header design (UEL vs EL) and engine (2.0USDM vs 2.0JDM vs 2.5 USDM).  Back when I had my lexus, the Megan catback exhaust looked *super* ricey, down to the angled fart can, but it somehow sounded mellow and nice.  Some of the prestige exhausts for that car with more of a 'real' muffler sounded raspy and ricey.

My plan is to stay with the stock header.  I like that it's cast iron and will hold up to abuse.  Plus my goals are for more low/mid range torque anyway.  Prob gonna PnP the manifold and get an x-pipe over the winter.  Right now I have a GS up pipe, front section of a TXS v2 DP.  Will be getting the cat section in a week or so.  Also have an AP so I can run stage 2. 

On a different note, were most of the head gasket issues resolved by 05 for the EJ20?  I'm going to be driving to UT and back in fall/spring and am wondering if I should be wary of it.  The previous owner was meticulous with the car.  Did regular oil changes, all maint, and just generally took great care of the car.  When I spoke with him he said that he never raced it.  That's what his Miata is for.  For that matter it's still on the original clutch at 144k which tells me he didnt abuse it.  Clutch still feels quite good actually (though it's on my list for spring along with a Primitive Racing flywheel).

My only knowledge of the HG failures were on the non-turbo 2.5's, supposedly resolved before 2005 anyway.  If you're concerned, you can replace the coolant, and don't forget to add the 'subaru coolant conditioner', a small blue bottle of stuff that's supposed to stop the HG issues.

Guessing that's a dealer only thing? I'm replacing radiator hoses and ancillary lines soon so I'll get some when I do that since the coolant has to be flushed anyway.
