Best exhaust system for an RS4?

[neilparf]

I said you are comparing apples and oranges when comparing cost of a 2.5 vs 2.75. I suggested you ask jcwf what the cost difference to go full 2.75, mandrel bent, quality stainless, 3.0 mufflers, 2.75 flex, clamps and vbands.

I said to make sure this is a true 2.75. To have a fully tooled setup for 2.75 is expensive. Often the bends are what suffer, so that's why i said to make sure it was a quote for it done properly not crimped.

If you want to discuss facts, I'm all for it. I think you're more interested in the drama, and remaining ignorant. And slow.

That's the point, you are not talking facts. You still haven't answered my question; 'have you seen the JCWF system up close'? Come back when you have.
As noted in previous posts, you should be a politician.

Spot on. Apples and oranges. A JHM system UK imported and all duty paid then fitting cost vs a UK supplied system = apples and oranges. Ignoring that, is as you say, ignorant.

...you are comparing apples and oranges when comparing cost of a 2.5 vs 2.75...

You started the comparison on page 5 of this thread in response to Rick_RS4's post.

Projecting old chap, projecting. Do you own a mirror?

...And slow.

This affirms the fact you are indeed approaching the age of 10...

Why do I need to see JCWF up close to know 2.5" is a poor choice for a 4.2 V8 that revs to 8250 RPM? What possible reason could there be? Have I said it's <beep> quality and the bends suck and the welds were done by Ray Charles? No. I said 2.5 is a poor choice from the start if you're seeking performance vs 2.75.

The laws of thermodynamics don't change if your 2.5" system is pretty. Nor will the cost of 2.5 vs. 2.75" parts.

I explained numerous times that citing the cheaper cost of a 2.5" exhaust is an advantage is foolish, as 2.75" costs quite a bit more, and as we have all seen (everywhere but here I guess) 2.75" is the best choice for the RS4 for performance. Would you advocate buying an A4 1.8 TDI becuase it's cheaper than an RS4? It's the same logic. One is more expensive because it's frankly better and more expensive to make. Doesn't mean the A4 is <beep>. Just means you shouldn't get your arse whipped in a race and claim a win because you paid less for your diesel.

If you want to convince yourself that your shiny exhaust and pretty welds is the best, that's fantastic, have at it. But don't talk through a hole in your arse. To be honest though, the forum would probably learn more if you farted than if you spoke. You're just another chequebook enthusiast who opens up his wallet and thinks he can just buy hp, without knowing a thing about what he just bought.

Looks like you don't want to discuss anything relevant. Speaking of politicians, you just ran in circles and avoided the facts altogether, and hurled a pile of insults in the process. Stick to farting.

You managed to push the stone up then after your brief hiatus.

Yeah, that's the one. Shiny. Wallet. Welds. Running...

Go peddle your s**t down the 1/4 strip...

Talking of strips, mine's still faster than yours.

Why do you say that 2.5" is a poor choice, irrelevant of who makes it. The title of this entire thread has always been Best Exhaust System for an RS4 not what exhaust is best for performance.

Im sure there are plenty of people who can qualify the aerodynamic and thermodynamic forces to justify why a 2.75" would benefit the Audi V8 engine, but quite frankly im not interested as I would say that 90% of people that own a B7 RS4 won't be trying to break any records up a drag strip, as I presume that most owners drive in the real world where traffic and other road users are in abundance.

personally I don't think that the JHM system is that good on a £ for £ basis, it may well give the best performance figures but as I stated above, most of the owners live and drive in real world situations so for an extra 10bhp over a 2.5" system is just not worth it and its not bespoke.

I have a JCWF system and I think it is Feckin awesome, I also like the Capristo system, but it is massively expensive, as ive stated in previous posts IMO the JCWF is the best system that you can get £ for £ with anything on the market in the UK based on quality of materials and craftsmanship and sound

I had a look at your video going up the drag strip and to be honest I didn't think it sounded all that special, you also had your arse handed to you by the driver on the left and on that basis I cant take anything you say at face value.

That stone is calling, Saki. It's cool, dark and has your name on it.

I too have watched that video of you going up the strip too - you should try actually driving first before you spout .25" is better...

Get's me thinking. Have you noticed a trend in the responses whenever you post...

when i read "best exhaust system for the rs4" i automatically think which gives the best gains, maybe im odd?.

i agree 90% of people who own an rs4 in the uk are not interested in the "strip", but to suggest that that they would not be interested in making more power if they could doesn't ring true when you consider how much money everyone pays MRC for them extra ponnies?.

personally i think the JHM exhaust is the best value exhaust you can buy for the rs4 on a £ for £ basis.
i drive "in the real world" and will take the extra free power over a 2.5" system, it is very much worth it.

also i dont get this "bespoke" thing?, are peoples rs4's different lengths or something?.

I understand your point regarding MRC, as I will be visiting them soon, I wasn't suggesting that people would not want to make any gains either by fitting whatever type of exhaust they choose, my point is that IMO for your extra free power down a decent road you would gain 1/2 a cars length if that, and to me I'd rather save the money for something else, don't get me wrong I'm all for gaining extra ponies, I just can't justify the extra cost.

Regarding "bespoke" I don't believe other RS4's are any different to mine, however I do like hand made products that show off British craftsmanship

Not odd, but that's your view and it's a perfectly valid one but it's not the only one.

"best" can be applied to not only power (and even that is a vague description as is it low rev power, high rev power, power across the rev range, more linear power delivery,...), but also to noise (and that is SO subjective), and appearance (everyone has their own opinion on that!), and probably several others factors too.

[Rick_RS4]

This isnt a JCweldfab slagging match BUT i am yet to see flow figures and to read it gives significant gains for the £2200 ??? cost, it maybe has been on a car for 6 months to see it is up to the job and not fall apart but even the milltek will give gains if you remove the precat.

sounding like Saki here lol but its alot of dollar for something that looks nice to the guy that services your car.

over in the states it has been tested numerous times, they are quite homo about it, comparing flow rates torque and hp, its quite an interesting read but also a minefield. the best flow for the 4.2 is 2.75 pipework, so the JC being 2.5 although looks sexy it isnt the ''best exhaust system'' , it took me a long time to choose the right exhaust system and finally settled on the EBwerks one, and imo it would be worth the extra £££ for the JHM over the JC.

I wasn't suggesting that people would not want to make any gains either by fitting whatever type of exhaust they choose, my point is that IMO for your extra free power down a decent road you would gain 1/2 a cars length if that, and to me I'd rather save the money for something else, don't get me wrong I'm all for gaining extra ponies, I just can't justify the extra cost.

why didnt you just buy a milltek if you didnt want performance? as the jc is quite alot more than one of those and not that much more gains?

Go and price up a full Miltek system from manifolds back including sports cats, and then price up for fitting the system, your looking at the best part of £3k

Now for my £2200 I had a full system fitted using better quality materials and craftsmanship over Miltek. There's nowhere within my post stating that I didn't want any performance gains, and yes my exhaust looks pretty to the chap that services my car he's a nice chap, yet as I said in my previous post I can't justify the extra cost

As you have said that those in the states have numerous tests regarding the 2.75 proving to be the best option for gains, I'm not questioning that, I'm questioning why someone would say that a 2.5 system is poor, surely using a 2.25 system would be poor or retaining / replacing the standard system with a like for like is poor

[Rick_RS4]

yes sorry i forgot the cost of the ridiculous milltek downpipes,its mainly a noise system and is far too overpriced for what you could just gut the standard pre cats and remove the centre boxes.

2.5 is not poor im not saying that, neither is the jc system, its just not ''the best exhaust''

if anything id say the 2.75 MTM one is as it has valves too, but thats only if you want your ass stretching for the money.

so given the cost of the MTM id say its the jhm one, ive not heard it in real tho, i bought the ebwerks one as it was a price i couldnt refuse.

I wonder what Arthur thinks...

The reference to the 2.5 being poor was not aimed at you, it was to "Saki" as to why he would use that specific reference to an after market exhaust system.

So to surmise for performance gains 2.75 is the way to go yet can be pricey, MTM will quite happily bend you over for the pleasure

For noise alone Miltek for a reasonable cost if going from the cats back, can get expensive with cats

For a mixture of both a little extra performance and a lot of noise go custom such as JCWF or which ever fabricator you
choose

I think we may have come to a conclusion ?
