hi all
i found a thread talking about that he installed MF X-pipes with his Borla+TP and it did remove a lot of the RASP that he used to have with his mod (there is a clip befor and after) :

1)did any one else try this ?

2) dose X-pipes work for every true dual exhaust ?

3) would X-pipes bring back the Z tone ? APS sound is good but i love the stock tone and the true dual gain

 

Yes. This isn't an isolated incident. Many have done this mod and have all claimed that rasp is gone.

 

just curious where this would go on a true dual, the hks has a somewhat of an "h" pipe with only about an inch from each other

 

h and x pipe are essentially the same. im sure you can find pictures of both on here somewhere

 

The X pipe can go anywhere along the length where it's convenient. An X-pipe and H-pipe are not the same. An X-pipe has well documented advantages. I'm considering replacing the H-pipe in my evoTT with a perforated X pipe muffler.

 

yes, the x-pipe has performance advantages over an h-pipe, the exhaust pulse balancing is the same idea though. in general, anytime you compare something that forces air to go 90* to the normal flow to something that is more like a collector, the collector will win

 

I've seen success on the borla, and injen TD so i think it'll work on any TD exhaust.

 

When I had Tp's on my borla I cut out the H in the exhaust and welded the two pipes together. They are only about 3'' apart enough to bur grind the opening bigger and squezed them together to weld. It made the exhaust flow so smooth with no rasp. I have fought this exhaust since the day I got it to get the sound and performance I wanted. If I had to do it all over I would have went a different exhaust. But you gotta love the sound of Borla..

 

anyone got pics of the h pipe being replaced on a true dual.

 

The Magnaflow perforated X does remove the rasp from Borla TD. I had this mod done as well.

I have to agree with these comments. As you say though... you've gotta love the sound that Borla makes.

 

Here is a reverse Y I had done last week. Tonight will video without the resonators. I had them cut off this morning... I have seen a pic on here of the X pipe installed somewhere.

well thats a good news,,,i`v found the pics of the magnaflow X-Pipe`s for true dual 2.5" exhaust :

i hope that i can find more pics about how it should be done

 

I did a custom fabbed x-pipe on my HKS. No rasp.

 

Sweet, that looks like the same way I had my borla. Flows great glad to see some else tried it. Did you fab yourself? if so great job

 

Nawww. I can't weld so good. I had a buddy do it. :-)

 

Yes the magnaflow x pipe removes all rasp. I put on my x pipe before my HFC's, and my borla made no noise at all.
Also I used the same x pipe as the OG that started this mod and he and I run this.

Looks way different than what's pictured above.

 

How did you put it before the cats are you sure you don't have it backwards and it's after the cats. Would like to see a pic

 

The custom X reduced your rasp on the HKS?
How else did it affect the sound on that system?

 

never heard of the company dose.

 

headers + testpipes + FI 2.5" true dual = no rasp

I'm gonna guess the Magnaflow x-pipe muffler helps a lot with this setup.
