Hey mates
i currently have a set of custom made 4-1 unequal length exhaust headers, can provide pictures later if anyone's interested, that felt better than the stock headers, but i'm able to produce ones so im seeking for the best design for peak power, online most posts are related to turbo cars, so cant really compare them

I know there are other aspects like runner length and diameter that are very important but design wise, whats better for an NA 1.3gti for the peak power/high rpm? Equal length or unequal?

Thanks

Equal length is better due to a few factors. Whether you will feel this in the car or not I do not know.

Link is a set of equal length headers made last year on a Gti engine.
