My new 3" d/p back exhaust

[Jamo]

I'll see how good mine is on the 24th on the Dyno as exhaust design theory is sketchy at best.
At the end of the day its all a bit academic with an OE manifold.

No not at all the difference is with the pipewerks system it's an easy upgrade to have a bigger downpipe and that it, complete exhaust system as the have removed the y section.

With yours if you upgrade the downpipe you need a new centre section or you have to step down from 3" to 2.5" then back up to 3" which is not a good design in the slightest.

does anyone actually have any real data on this to show the difference between the two? I'd be really interested to see the bhp unleashed or restricted by this discussion. Theory is very well but real results speaks volumes

[s2avant]

The Western RR results show the difference a 3" turbo back system can make. My car with stock RS2 software made 361HP/371lbft which is 45bhp up from what we expected. IIRC we estimated that it was around a 10% power increase when you take into account the rollers seemed rather generous across the board.

At the end of the day, I only spent £500 (not £800 which is 1/2 the price of my entire car!) on mine and am happy with it. The results on the 24th will speak for themselves. If you are a gas or piping engineer then I will listen to you, other than that it's just p**s and wind.

well, it will be interesting to see, cos we both have homefry's - you have air filter as well, mine is just boggo. ....
Ever since getting my new exhaust, my turbo has been squeeling like a pig, so if I'm down on power, I'll just blame it on that

Nice one. It just gets to me that nobody can be happy for someone on here. Initially people are interested and are positively or negatively constructive. I am not on here to win friends (nor create enemies) as all of us know the internet is full of idiots and psychopaths.

My last comment was a general one in that if you are not an expert (that doesn't include self styled ones), and don't have anything of use to say, or in fact, nothing nice to say ,then why not just STFU!

You've probably gathered by now that I don't "suffer fools gladly" and that I am in fact a misserable git.

Anyway, back to the matter in hand, my exhaust is better than all of yours and my dad is bigger too!

Thats alright, mine now makes a funny rattly noise. I think we should stick together, doctor our dyno results to show 400bhp and piss everyone off!

many have done it before. just remember to get the torque and HP lines to cross at 5252 otherwise its non too convincing

At the end of the day it's your money and if your happy then I wouldn't worry what others think but I am glad you made the above point as our systems are made by someone with over 25 years experience as a gas/piping engineer who started the exhausts as a sideline to his business, it now caters for 80% of his work.

At full boost does your rear silencer sound like a whistling kettle? Or is this the rattle you are describing, is the noise there on boost but not off?

No whistling kettle. Get the rattle when revving stationary so off boost. Just a rattle from my d/p heat shield, thats all.

See thats exaclty the kind of data people can form opinions against

If you're interested Corey (and you can offer a suggestion) mine only makes a noise on max boost and the noise sounds like the turbine blades scraping the turbo housing - a kind of metallic grating noise I guess.
Only happened after new system fitted - oh and the exhaust fitter was twattin' my down pipe with a hammer to make it round enough to wled a flange onto......this did worry me slightly. (sure I have no boost leaks as its boosting upto 1.4 ok and I have samco's)
doesn't seem to be affecting performance any

Mmmm. That sounds nice
