[CORNERING PERFECTION]

Hi Guys,
I'm thinking about putting a stage one on my spi, i already have a different back box, not sure what it is as i didn't put it on, but it sounds good, it's just a straight pipe to the left hand side with a turned over lip (if that makes sense!). Will a stage 1 make a difference performance wise, i know they say it's about 35% increase, is that maximum or will it actually affect it that much.
I'd appreciate your input guys!
Cheers

think he means he has an exhaust from the cat back. i'm sorry i don't know about the power gains to be had for an spi, i had one a couple of years ago but never got round to engine tuning.

I would think that a 35% increase would be optimistic on the average car. I believe there are a few articles about these kits on the minispares website.

Cheers for ure input guys, to clear things up i did mean cat back exhaust (sorry). I think i'll go for the stage 1 regardless, it's worth a go to see if there's much difference!
Thanks Chaps & Chapesses!

let us know what the difference is if any, because many people are probably debating the same mod. Cheers *
