    Sportback Is stage 2 worth it?

    Iv a prefacelift tuned stage one by Rick at unicorn, just secondary decat and intake pipe, running 420 and 450ft/lb Is it worth the money to buy Down pipe and intercooler for the noticeable gains you get back? I will most likely never track the car. I know these suffer with out an intercooler...

    Cheap non-brand downpipe

    hi, has anyone got a cheap unbranded downpipe and are they any good? Found one for £140 which is stainless steel and has mandrel bends so surely it can’t be that bad as it is just a pipe at the end of the day? cheers

    Decat question (2.5TDi)

    Hello, the other day I removed the two back boxes of my 2.5tdi in hope to get that v6 growl, but it hardly made any difference in the sound. Would removing the pre-cat and 2 main cats make the car louder? (I dont really wanna remove the center box)
