My experience !
Hi all,
I've owned my 1.9 TDI 160
Cupra for a few months now. Just thinking about getting a cat back exhaust for it to give it a bit of noise! Wondering what people have fitted and what is recommended? I've seen loads of the Miltek non res ones for sale on ebay.
If anyones got and videos/sound clips that would be great
I have had a few different combinations on Mk 4 TDI
Cupra, I'll try to keep my explanation simple.
First I removed the cat from the standard system, which seemed to speed up spool and power slightly. Noise was fine.
Next removed back box, basically straight through standard system, a little more power and spool but sounded (in my opinion ) like a tractor.
Tuning work followed with a hybrid and remap, the car then produced 220bhp, and pulled like a steam train from 2k.
I then investigated aftermarket systems, but I feel the thickness of material on some systems is very thin for the price. I decided for a full custom system from Darkside, at 2.5inch straight through with single back box. Also the tail pipe is slash cut facing the floor so any smoke just hits the deck ! Sounds amazing with a deep growl and even quicker spool, worth every penny and a similar cost to an off the shelf system. I'm going to Dyno the car after Xmas so I'll be able to record the improvement. Another custom builder who a friend just had a full 3inch system built is Tony Banks in Leeds, real quality product.
Hope that helps!
