De-Cat Power Gains

[paddy88]

Hi there i have a standard saxo VTS with a cat back powerflow exhaust, i have reciently orderd a piper de-cat and i am just wondering roughly what power gains i am looking at evan though i have a standard manifold on? also are piper de-cats anybetter then regular de-cats?

Thanks Paddy :y:

I found that pick up was better and also throttle response was very responsive, makes the vts sound awesome too:y:

Suppose most decats are the same, there just straight through pipes.

got a decat, 421 manifold and pipercross viper induction kit on my vts, drives mint, the decat makes it rev more freely! definate must anyway! sounds great at 7500 rpm :) also superchipped!

Is a de-cat better than a sports cat.

i think so yer, am guessing the sports cat duznt let as much gasses through as easy compared to a decat, as there is still some restriction! i have just put mine on but its not welded on and its blowing a bit! :-(
