Hi everyone, been looking at taking my back box off and replacing it with the straight through pipe with the cupra r petrol tip, does anyone have what this sounds like on it's own on a PD150? (before and after would be amazing!) (Ideally an FR Leon) (without remap and without changing anything else in the exhaust system? would love to be sure before I go about getting a pipe done :) cheers.

Just done my ibiza pd130 and its not loud at all. I gutted my cat last week aswell. I still have my middle box in place so think that will be next to go. I was hoping for abit of noise when I let of the throttle.
The car does seem to pull better now with minimal lag.

I wouldn't get rid of everything in the exhaust if I were you,keep at least 1 of the boxes or the cat,if you go straight through from turbo with no back pressure you run the risk of drawing oil through the turbo. It happened on my leon fr and I had to put the cat back in.

I had a MK4 Golf GTTDI with pipe from turbo back, and IMO sounded GREAT!! Back box will be minimal, get the lot out lol!! Ran that old girl like that when I got it at 150k to 185k with no worries at all...
