X-Pipe for E55 ?
Hi everyone!
I've recently put back my resonator(I had mendrel bent pipes) because I felt the engine had no power before 2000rpm. But now I am kinda regret about what I did because the car is a bit slower on the highway and the engine is not as throaty at higher rpm
This had made me thinking about other ways to improve the performance of the exhaust system:
1) remove the second set of cats and replace with straightpipes and keep the stock resonator
2) change the second sets of cats to high flow cats and keep the stock resonator
3) replace the resonator with magnaflow X pipe and keep the stock cats
4) X pipe with high flow cats
5) X pipe with no cats
Also I would like to know what exactly does X pipe do? are the stock cats very restrictive? what would be more noisy: remove the cats or remove the resonator?
cheers,

Ususally an X of H pipe is used to equalize exhaust and back pressure on both sides of the engine and exhaust, it usually yields to improvement.
I'd think that removing the second set of cats and putting an X pipe shuld help, but then again it really depends on exactly where you put the x pipe, I've heard and if missed by an inch it can hurt you, if done at the right place it will help you, that is the tricky part, to know exactly where to put it.
