Pipewerx 3" Exhaust Down Pipe High Flow Sports Cat Help

--- Quote from: rashg60 on May 31, 2015, 09:13:55 pm ---Also, just to be clear, the vast majority of the gains are achieved by the downpipe and sports cat - so why would you spend another £450+ on the cat back system? I'd be inclined to leave it alone if it's not even another 5bhp for so much money!
Unless I'm missing something of course........

Your right. If you are after more than 330bhp then a larger bore cat back is required, but up until then the cat back is for noise and looks :happy2:

I've finally saved up enough pennies for this but have been reading other people's thoughts on the exhausts and it appears that most people go for the 2.75 inch pipes. What are the main differences with the sizes (apart from the sizes of course)?
I just assumed that the 3inch pipes would be better as they are bigger? What is the standard size of the exhaust? Pipewerx tell me that their 3 inch pipe would fit the standard back box system.

Standard size is 2.5inch. Milltek is 3inch downpipe to 2.75inch catback and other brands are 3inch.
i got told the milltek offers better torque but less hp. Wont be a problem on stock turbo tho.
and yes the pipewerx bolts straight onto the oem catback as it has a reducer to fit.

Did you end up getting one of these?
Wondering does the Pipe Werx downpipe and sports cat show up used often?
rashg60:
Not come across any used ones on eBay or anything but I think for that price I wouldn't mind going for new (as I'm intending to keep the car long term).
Unfortunately not ordered yet. I've had some unexpected house-related expenses come up (roof and garden shed). Gotta keep the missus happy. Exhaust money has gone on roof......nnnnnnoooooooo!!!!
It just means I have to wait another couple of months for my precious exhaust. I have decided to definitely go for the Pipewerx downpipe and sports cat though. I really cannot wait.......
