springs and downpipe

[850twr]

ok couple of questions, if i was to replace my downpipe for a feritta de-cat one designed for my flat flange 15g, if i where to later upgrade to a 19t would this render it useless, or will it still fit?

second question is regarding suspension. I've decided to keep with my stock shocks, because i don't want my brain rattling in my scull over every bump and because i've only recently replaced all 4. so have decided to just get some springs, theres loads on the market, all seem to offer a 30-40mm drop and was just wondering what everyone recommends.

the different springs I've come across are, Eibach, PI, ROC, GMAX and the ones I'm leaning towards are APEX as i know they have a very solid reputation amongst the Japanese scene, they are the most expensive at £150.....

but think could well be worth it.
any thoughts guys?

Go for H&R springs. The downpipe can still be used with a flat flange 19t if designed for a conical 15g but you will just have to split the turbo at the Vband clamp and swap the cores over. Its a very easy job but you do need to be very careful.
