Exhaust systems for Cupra tdi

[paul26982]

scrapping the short shifter fo the time being until i get preformance mods done, ie., forge intercooler, filter re-mapp and exhaust system, because the 180quid could go towards the exhaust, so what do people recomend for the tdi cupra, i know on the petrol miltek and supersprint are recomended, do blue flame do one, what are they like, wanting good value for money

try that...lots of info mate.

 

[paul26982]

not looking at power flow as ive heard mixed things too

 

[slick]

As phil pointed out, save urself the cash and get a straight thou pipe, from the cat to the pipe tip, saves the weight and frees the flow up a hell of alot....

as for the intercooler mate, if you own a 150pd, there is no need to change the intercooler even forge know that a replacement isnt much of an improvement on the standard intercooler as its that effecient.

So spend the money on a straight thou pipe instead of the box, get a BMC, Carbonio or etc and then remap, and I'm sure your be smiling...

But word of warning with the remap you may find a clutch upgrade is needed to use all the power given, as the clutch has minor problems with slippage in some remaps....
Then get a short shifter and ur laughing...

Well i am... look at what i got fitted... lol Excately the same...

 

[paul26982]

so what do i get and ask for regarding the straight through pipe, will that not effect mot, and were from and price

ok, You ask for a new stainless steel pipe from the cat back to replace the back box on it at the moment.
So basically you remove the back box and replace it with a plain pipe, cost from £95 to 150, depending on where and what tip u use. This can be made at any exhaust manufacturer including powerflow, as long as its 316 or higher grade stainless steel.

the MOT wont be effected as you think becuase TDi's are tested for soot not emmissions and also the soot is due to the remap, so if you have a good map then no soot.
Hope that helps...

Well to understand stage two, which i pretty much am on the brink of doing... to be in the area to replace the standard intercooler due to being not effiecent enough would mean, i have fitted a new set of PD injectors costing over £1000 to buy, then get them fitted, £300, then to have a new Custom remap designed for the injectors, exhaust (idea of maybe removing the cat for a race version) that without meationing that the new clutch would have to be replaced with an even stronger version as the intercooler to my understanding is good for what the injectors are good for... 225-230bhp....

so unless you going stage two anytime soon, the intercooler change for you would be visaul only and not a performance upgrade....

 

[paul26982]

ok thanx, also straight through pipe, would it not be really loud

 

[slick]

not loud if its taken from the CAT back to the tip, if its taken from the turbo back its louder, the CAT acts as a silencer abit.... theres various sound files on that link Phil put up here, one with the straight thou from cat and one without the CAt, and ur tell the difference!!

 

[paul26982]

so from a full s/s to a straight through pipe are the simular performace

 

[slick]

The performance gains from removing the back box or the CAT i dont have a idea on, i know it frees up alot more flow from the exhaust so if thats true, if you havent already permantely blocked the EGR valve if the exhaust gas freely flow out quicker means more fresh air for the engine...but its all theroys only one way to test, RR before and after, but even thats not fair as ideally the ECU should be mapped to the free flow exhaust system... so basically it for show abit of noise and freeing up revs... not for bhp gain... bhp gain comes from the remap and that enough for most, till which time comes for injectors, upgraded turbos and etc...

EDIT:

At this point you wanna think, do you have that power able to be put onthe tarmac and also have you take that speed into a corner... your find alot of that is no, so upgrade the suspension and stiffness, rubbers, the clutch, the Diff... all gets expensive in teh end.. i spent over 5k in engine and suspension mods, not even put in for the injectors, turbo and custom remapping... close to another 3k just for that, but i know that the chassis and suspension and drive system can take that, when i put it on...

The way i see it is...why have all that power if you cant corner on it... just end up being liek a yankie car, all the power in the straight line but put a corner to it and its over...

 

[paul26982]

im getting mixed reviews tbh m8, like on says

if your getting a new exhaust get full turbo back system no boxes, cats except for a backbox this way u will see the most gains i personally dont rate powerflow they are cheap for a reason u only get what u pay for imo. Blueflame seem to get good reviews i know ryan has one on his leon and he really likes it

Hi mate, serious question here. Why spend that kind of money on a 150 TDi, it just seems like madness to me, why didnt you just but an R to start with and save yourself a fortune, the £ saving on the diesel surely is obliterated when you start spending thousands on it. I just cant understand why you would do it. I can understand maybe a remap and an exhaust and maybe some air filter dabbling but over 5k.

 

[paul26982]

i would have bout a r if they did a diesel version, but dont think the above is aimed for me

its called each to theyre own , why didnt each of us just buy the top spec vehicle and live with it , indivuduality says a lot

Not really, most would buy the tdi 150 to save money on tax, fuel and insurance whilst having a nice looking nippy car. If i lived 3 miles from work i would have gotten an R. Im not having a go im just trying to understand why you would spend so much getting a diesel up to stock R bhp when you could have bought an R and saved over 5k!!. If its a project fair enough as i say im not having a go i just wonder was it all planned from buying the tdi, or did it snowball, my question is to 'slick' really.

 

[slick]

Well as it states above each to there own...

I brought the car as i did cover alot of miles to and fro from my gf house, but now i live with her and basically dont do the miles anymore and well i had abit of spare cash to use on it and basically i thought, who else has done it?

So i looked at where i could improve on the TDi, the engine the suspension, the drive the diff, all the above to make it one off car... yes i could have brought an R but why, so i can have a petrol car that eats a tank in 360 miles and well is pretty common around in essex...
So i thought i would want a car that isnt common, to do that you need customised....
ANY ONE CAN GO OUT AND BUY AN R, but no one can be buy mine, i mean in theroy they could, buy all the parts i did and etc, but its was mostly one off or made myself, this cant be brought of the shelf...

in reality i couldnt explain why i do it, i could till I'm blue in the face but the problem is some people dont understand spending more money on one car instead of buying a standard faster car....but i have an allergic reaction with the word "Standard" lol, but others will know excately know where I'm coming from, as they will cherish there cars and love the idea that there car is one off... but most of all, there not looked at in their cars in a way say a Scooby, BMW, MERC drivers are, all faster cars stock than a Leon but as you read on here everyday, people mod them so in the end they embrass the likes of all those above drivers in a VAG car!
But the difference with my car i started that journey in a deisel as petrols are done already and well its the pefect base to have a really one of car, because as you say WHY spend 5k on the diesel car, proof enough that my car is really going to be one off.......
