Xforce Exhaust Thread

[serdar]

so smb and ces make their systems using small sections welded together! esp their dumps

so who makes proper full length pipework then? with weld joins only at flanges and mufflers etc?????

It would cost alot of $$$ imagine the labour that would go into the amount of times someone would have to put up a piece of pipe under the car say "yep needs a bend there" go and mandrel bend it then go back and repeat the process over and over untill u reach the cat and then go from the cat back and so forth lots of money!!my uncle owns an exhaust shop here in sydney when they do custom pipping for hotrods which is basically extractors that hang out to the side of the car it costs a few grand...I think anyone of these systems would be good as long as its not standard...

-bigger dumppipe to quickly dump that gas out of the turbine housing

-bigger diameter pipping to allow for flow

-high flow cats to replace restrictive stockies

-straight through mufflers

you will see good results with any aftermarket fullsystem just depends on your budget

Would custom make that much different where exhausts are concerned though?

Yes, it can be made to suit your requirements.. (flow, sound, etc)... In my exhaust, everything was custom made including the mufflers.. With anything "off shelf" they generally try and find at happy medium for their potential customers.. Also, because they are bulk made this is where quality and fitting issues can be a problem.. IMO

Not saying custom made is the only way to go, however I like being able to have input in what I am buying and dealing with a professional that backs up his work 100%.

At the end of the day, SMB, Xforce and CES are all "off the shelf" exhausts..

For the money you pay for the SMB/CES you might as well get one custom made..

Agree. My point was CES systems are all 'custom' in reality. Trevor has jigs and templates made up - that's it. He also hand makes the mufflers. Given the status of the shop, I was expecting he'd have a 3 axis machine or similar so once he'd mocked up a car and saved the file, all the zorts from then on would only have welds on the flanges etc. To a certain degree, even xforce do that.

[TITO]

CES system will support over 500rwk, the only time its 'custom' is when you cant buy it off the shelf for your type of car or you wanna tell your 'Bro' mates its 'custom mate' [I put this term in the same bin as 'file finnish used years ago] Welds in the pipe work wont rob you of HP or rob you of flow the part where you are robbed of flow is where your 4inch dump meets the exhaust housing. Ces seperate the turbine and wastgate with there 3.5inch twin dump pipe perfect for flow. SMB would be my choice if I wanted 4inch still not seperate like the CES but a nice flair off the turbine housing.

I will go for the ces twin dump and 5inch cat for my FG.

[bossmang]

lol what smb would be your choice if you wanted 4 inch?

but your going ces?

[TITO]

SMB stleath dump and cat because his 4inch is a better shape at the turbine end than other 4inch dumps [the few I looked at anyway] I was trying to say if someone wants a 4inch dump I think its a great choice.[my opinion]

I like the CES dump because there is minimal turbulance at the turbine end of the dump pipe. Worked with a mob called Bensons Turbo shop many moons ago in Sydney played around alot with this sort of thing back then.

Funny enough now?

My 3 1/2 xforce supports over 700kw mind you with a cat mia & the rear muffler being changed to a straight through resonator lol. Rear mufflers were crap, even at 17psi we were losing 25hp & the cat died after 3000klm. the pipe work is good but other components were less than up to the task

[Bomber]

Agree if the welds are done right (and I'm sure CES systems are) it won't cost you much, if any flow. When talking mild steel though, the more welds, the more places the zorst can and will rust. A true mandrel system isn't knocked up with a series of bends sewn together IMO. Not for 2.5k anyway. Even if you replaced the rear muff on an xforce and fitted say a magnaflow, you'd still be cheaper. Plenty are making 400+ with xforce in either 3.5" or 4". Bang for buck for a street car, I don't think you can beat them.

In theory if you knew how to weld ok you could knock up a CES exhaust from universal bends off ebay for probably a third of the price. Point being it's nothing special, on the other hand not everyone has a machine to mandrel bend pipe. It's not a quick process either but the best that's why it costs more.

Yeah, I could weld up a dump pipe myself but I hardly have time to drive my F6 these days. The special part of the ces system is seperating the exhaust from wastgate at the turbine end of his dump pipe.
