I noticed some exhausts... TME, JETEX,etc...have dual pipes coming back from the muffler. Is there any benefit or negatives to doing that over the single pipe with single tip? Different air flow or sound?<p>Also, I love the 3" EVolve exhaust but am concerned with the ECU upgrade. Do I have to match the ECU upgrade with the exhaust? For example Rica uses 2.5" Ferrita, but could I also use Jetex for example?<p>Also, IF I were to go with a 3" Evolve exhaust and use the BSR PPC ECU upgrade...BSR specs it for a 2.5" exhaust. So this would not be a good thing for me to do?

exhaust will not make much of a difference if any at all in regards to an ECU upgrade. A DP on the other hand could make quite a difference. For best results do all three.

Re: (MASH)

So I guess that begs the question; is there an ECU/DP combo that work "better" together with regard to performance etc?

Some are just more rumbly (e.g. 3" resonance), others are real quiet except under WOT. Check out my exhaust thread to hear sound clips. <p><A HREF="http://forums.swedespeed.com/zerothread?id=46924" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=46924</A><p>Exhaust doesn't really affect your ECU that much, like someone else said, DPs since they are attached to turbo may. If you are going with BSR, keep your DP stock and go with whatever exhaust you like. Ferrita and Jetex are my favorites for looks. <p>Also, I spent some time looking at Ferrita on Jesse's car this morning when it was in the air. It has some really good points. First off, it is a 3"- 2x2", best design IMO. Also, it fits really well on the car. They maximized the rear muffler space, why it is pretty quiet. The attachment points were well placed to give good ground clearance and still provide haldex clearance. <p>I like the 3 point DP/exhaust connection, but don't like how it sticks down, A couple of people with lowered cars just cut third bolt hole off since it scraped sometimes.<p>They crammed two really big exhaust tips in there, but the tips go all the way back, so visually it looks good from the side. Jesse's tips really need to stick out another 1-2" IMO, but maybe different on other cars. <p>And lest Johann let us forget, the Ferrita was on his R when it hit 400hp, so although there may be a couple of places for improvement (e.g. male-female split), it flows quite well. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

It is not designed properly to fit right. To get good fitment you need to cut off the hangers that it comes on and weld them with a slight offset or longer hangers to get it centered properly. This costs 45 bucks at Meinike.

they have been making this same system for nearly 3 years now. i would not count on them changing this. If change were going to take place I think it would have happened by now.

Re: (R_Rated)

Well I thought they were looking at the issue of it lying too low. Imprecise fitment issues was another concern. Could have sworn Keith was looking into it...

I don't believe in mixing parts, after a performance parts company did all that good R&D I'm sure they know that their combination maximizes their parts potential.

It is if you don't want to experiment, Its like plug and play and you know it works. but if you like to tinker go with the other options.
