Series 1 MPS3 Down Pipe and Mid Pipe Recommendation

[Malicioso]

Well I have recently removed the Baffled muffler from my MPS3 and had it replaced with a straight pipe, the different note from the exhaust is a real nice feature from doing this mod but also the slightly quicker turbo spool is bloody awesome and unexpected!

This had me pondering if my next modification (power wise) should be a new DP and perhaps replace the mid pipe???

I'd like to get an idea as to what others are running on their cars, mine is thus far "stock" for the exception of a modified air box and the muffler delete.

I should also mention that I have a DP and Mid pipe combination in mind, but not sure if this will throw a CEL.

The Dp is UltimateRacing Catted (Metal core) with o2 sensor bungs.

And UltimateRacing Catless Test Pipe

i have read on many US forums that the Gen 2 guys love their products and swear by the craftsmanship and quality of the Down Pipes. Has anyone had any experience with Ultimate Racing or purchased their products????

Any information on the above will be greatly appreciated

Hey Alex, i think you probably know but i got 2XS race pipe, and no cell since the 2nd cat isn't monitored i'm thinking doing the straight through pipe your talking about too .

Gotta be careful thou cause the Top half of dump is 3" and so its the race pipe but you'll have to get an adapter to make it fit onto the 2.5" system.

But im thinking along the same lines as you for a new top half of dump, but ill probably be in contact with 2XS for that i think he told me approximately same price as ultimate racing... dont forget you have to add installation onto the cost :S.

Installation is no problem for me, I'm more than able to carry out most installs my self so yeh

Yes I think I read somewhere that the second Catalyst does not throw a CEL but the location of the #2 o2 sensor might.

The only other option would be a COBB DP since that replaces both catalysts and its one single pipe from turbo to the factory CBE flange.

Though the UR pricing makes their DP really appealing.

Dont bother with the race pipe. If dump is withing budget go that for sure.
Either go with the 2XS item or Best Mufflers.

No race pipe you think???

I was thinking on getting it because that would mean one less catalyst and just run the one on the DP, less restriction is what I was thinking by doing this.

Might have to PM Troy with regards to pricing so I can compare with other options.

with regards to UR I would have to either get the DP shipped from the US or go through their Aus dealer in WA.

Most full DP's only come with 1 cat at the bottom of it anyway and being a Full DP it replaces from Turbo to where the race pipe would finish. If your thinking of doing them and the same time i would recommend Troy's DP but if you like me and only had the options of doing 1/2 now and possibly 1/2 later the Race pipe is a good choice, the only disadvantage in this is that im not sure if 2XS top half of the DP is 3" and obviously the race pipe is 2.5", comparing to a full 3" DP would flow better.

How do you find the engine mount alex?

[Malicioso]

Bakis: Yes I see what you mean, though what I like about the UR setup is that the mid pipe can be replaced at any time to make any sort of combination since the DP and Mid Pipe are separate, would come in real handy if running a cat less mid pipe and require to change it to a catted one or a resonated one.

Also the pipes look close to factory since the configuration is the same, and yes doing the DP first then the Mid if needed afterwards is yet another advantage from a cost point of view.

The mount is bloody great! I'm yet to give it some to see if it has gotten rid of the wheel hop, but the car feels very much more tied together and the vibes are fairly bearable, I've owned cars in the part that vibrated much more than this!

All the restriction is in the first cat. Further back the better, Alex
Lose the first, keep the second cat

[Bakis]

or you could go catless :P

or you could check the FS section and pick up a CP-E Down pipe which does both down and mid pipe (also part is in Melbourne) just for another option
