Cupra 280 Downpipe decat with Stage 1?

[Giox96]

hi, I would like to do a Stage 1 on my Cupra 280, but before doing it I am undecided whether to put a Downpipe without Cat, in your opinion is it worth it? In terms of sound, does it make too much noise? I already have a modified exhaust that makes enough noise, I wouldn't want it to be too annoying at low rpm, but in terms of power will I get a perceptible gain?

If you're fitting a downpipe its Stage 2 you'll need not Stage 1.

As for decat, I don't think the gains are worth it over a sports cat and the downpipe with sports cat should give you enough noise that you may want to add an extra resonator in depending on how loud you like it.

Why?

I can ask the same question. Why have a car that smell bad and pisses people off behind you. But I think I know the answer.
If you don't care for others or live alone, the benefits will be above 150km/h but for a stage 1 you don't even need an aftermarket air filter. So if you want pops and bangs, antilag with flames poping out, I dont think that you are asking the right questions. The best thing to do is having a target. Go to your tuner and he will tell you what you'll need for the hp you want and do compromises with the budget you have. Just find a good tuner with experience in EA888 gen3 engines.
