    sportex 3" exhaust?

    anyone got one on a mk4 astra hatch?

    i currently have a restrictive irmmy dual d backbox and like the look of the sportex 3" round backbox.. can anyone post a pic up of one, and will it give me a sliiiiiight performance gain over the irmmy one?

    do you not like the irmy one? if there was a again to be had, id imagen removing the centre box and putting a "race" ( striaght through) pipe on instead, there will be an increase in noise and possibly power. but going back to the sportex back box, alot of people on here have them, and im pretty sure they would recommend.

    hope any of that helps.

    as above mate - id recommend keeping the dual Irmscher backbox and fitting a non-resonated centre section (ie no silencer) this is the best of both worlds and produces a nice roarty sound with the style of the irmscher tailpipes

    Sportex on the other hand are renowned for their loudness - even a rearbox on its own is quite noisy - and noisy in a bad way imo

    I agree with the noise. My mate a had a cat back on his 205GTi and it was very very loud. He was a bit annoyed with it after a week as it was too loud and drone-y on the motorways.

    They are quite raspy as others have said, friend has one on his corsa sport with a centre section with silencer, sounds lovely on idle, then you hit 3k rpm it rasps a fair bit

    I swapped my irmy back box for a sportex 4" oval and also centre section...looks ok, sounds ok on the outside, but inside the car its bloody annoying...tis quite irritatingly noisey and reverberates around the car...i soooooo want the irmy back on again!! *slight* price difference though!!!
