I dont follow the sheep as such when it comes to buying exhausts, cause as far as I'm concerned its money wasted for no real gains.
If on a buget remap,change backbox,panel filter.
The back box is the biggest restriction on the TDI, not the rest of the system anyway.
That would be dependent on if its stock, generic mapped or customed with over the standard map upgrade to about 185bhp, I would say if you are going above this then back pressure would be a concern, but running a standard map wouldnt neccessarily need an exhaust upgrade IMHO, for the difference you get I cant justify £500+ for very very little gains.
Now take Dunks & DevonMikeys systems, they would require something upgraded on the exhaust side given ones running 240bhp & other way over 300.
I see no real mind boggling benefit to having an exhaust upgrade unless we're talking something along the lines of these 2 examples.
But seriously as I've always said its not mind boggling improvements is it, come on for what they cost I would need to see something fairly substantial, you show me a graph of my car for before & after map & that would be something to say yeah it was worthwhile, but above doenst light my fire as such.
I think it starts to really benefit you when you start to do some serious tuning like Dunk & Mikey have, for generic mapping I cant see the cost being worthwhile.
But this is of course only my opinion, I just like to see alot more for my money for something that cost so much.
This is where we differ then, I would never buy an exhaust for what it sounded or looked like, sorry but that seems rather boy racerish to me, I'd rather it was functional & actually showed me some gains than it be gurgling like a V8, never did get that tbh, I mean how often do you look at an exhaust on a car or stand there listening to it, lol.
I would however buy a exhaust for the gains & have it styled to my car as then it would be functional, but if it didnt provide anything of use then no point wasting my money.
We could discuss this on other parts of the car but I see a point in all my mods, mainly to learn something.
You got very defensive about the value of some shiny knobs on your RNS-E I'd rather have shiny stylish tailpipes than 2 bits of silver plastic. But that's why any mods are a personal taste, and of course why our cars are unique.
As to how often do I stand there listening to my car? Never. But I do drive it, and enjoy the sound the V6 makes.
Is the remap graph you have posted above a 'manufacturer supplied' chart, or one specifically for your car Pete?
Whilst being the primary agent for the removal of spent gases from the engine in the most efficient manner, exhausts also provide the manufacturers some scope for controlling the flow / back pressure of the system to either bolster torque figures or outright BHP.
I'm no expert on exhausts, but I guess there is a balance for the buyer to strike between drivability / emissions control (for cars in MoT space) / sound / appearance.
Back in the 90's I had a Mk2 Jetta GTi 8v, and after an engine upgrade (TSR Donington 1.9 litre), I had a full exhaust system + manifold (3" diameter pipe). The results were terrible for around town driving, and I found I lacked midrange power as the lack of back pressure meant it was slow to pick up. However, in contrast it gained significantly in performance over 100mph when the gases were really flowing and kept pulling far harder than the stock system.
This is less of a problem in turbo or higher capacity engine cars as they deliver far more torque than an NA unit.
For people who want absolute power I can see how they are of benefit as the power curve is sustained at high RPM's. However for general road use I don't think you always see the benefit vs. the outlay. Don't get me wrong, if money was no object then I wouldn't care less, but I personally feel there are mods which return more outright performance / drive improvement for the same kind of money.
Sorry, got bit bored there, made me tired.
You simplify a previous discussion that needs to be put to bed, continue if you like but it has no revelance to this healthy thread so move on because I will ignore & I'm sure others will aswell.
Back to the discussion:
Everyone to there own, but to buy an exhaust purely on sound & visual effect IMHO is silly, considering 95% of the exhaust is under the car, then whats so appealing about the tips, if asked if I like a certain look I will say ye/no but it isnt my underlining reason to replace.
I have desires on a new exhaust for my car thats styled to the valance, but this is only because I might go the hybrid route which would ideally need the better exhaust as already mentioned by Dunk for one & since its an expense based on the improvement overall then seems logical to make it suit the car better aswell, but until I do the upgrade exhaust wont be changed.
I just dont like this gotta have a Milltek cause its cool thing,(yes I know yours is remus) but its the overall feeling of naturally having a better exhaust is going to make your car become a Veyron, lol, cause although alot of us know its not the case, there are a fair few that also would think it would do this, simply, it wont, as Warren said recently for the gains & expense, its not worth it given the gain of bhp to the pounds cost.
But like I said, this is only my opinion of this matter, I didnt say you had to agree with me.
I bet my shiny knobs on my rns look better than your not so shiny exhaust tips, lmfao, give it a rest ***, it was months ago & tbh you've simplified the situation to your liking, move on.
Veyron was a analogy example not making a direct comparison of power, you're not a stupid person so dont act like one, you clearly understood the point I was making interms of the power increase some people expect from changing the exhaust over.
So you gained a few hp for how much again, was it worthwhile overall for the cost, for me no, for you well thats your decision, but for me I'd want more than a few hp to make it sense, £500+ for few extra horses is pointless, the graph shows only a difference of between 200rpm's in reality so didnt make a huge difference IMHO
My exhaust tips are nice and shiny thank you! I may have oversimplified the situation slightly, but like you, was trying to make a point - you value your shiny knobs, I value my tailpipes.
I didn't understand your point re the Veyron - any conventional mods such as air filter, exhaust, etc. give extra power without putting any stress on the engine. A remap in it's very nature will always be the best bhp per £ as it's software and inexpensive. I don't agree why you feel everybody who has purchased an exhaust has unrealistic expectations, I expected a few bhp and got that I'm sure.
Very little info on tdi club is relevant to PD engines as most of the people posting haven`t even seen one as it`s mainly an American site. The stock PD140 injectors will flow more then enough fuel for the stock turbo. It`s the turbo that will need replacing before the injectors for more power. It is possible to buy uprated nozzles though and they are called P1287+ which will then have to be fitted and tested into a set of injector bodies.
