    best exhaust filter combo for performance on 1.8 sport

    Hi, ive a 1998 astra mk4 sport, 1.8 16v. (any 1 know what the engine is? x18xe1? or x18xel? Or am i totaly wrong?)

    I want a new exhaust system, and induction kit or upgraded filter.

    Dont want the exhaust to be too ott, just give a nice rumble at idle, and a bit of a growl when you floor it.

    Ive heard good things about jetex exhausts on the mk4, any 1 had these dyno'd on a 1.8? what figures they reach?

    sorry for the mundane post, but i really dont no what to go for, thanks

    I've heard good and bad views on powerflow exhausts but they do seem to be pretty cheap

    yeah powerflow seem to be good sound wise, but ive heard alot of horror storys of the very poor materials used. Also these arent really designed for performance as there just built on the car with no testing or development.

    Does any 1 know the main uk importer for jetex?

    There are a few options other than powerflow being:

    Jetex
    Magnex
    Janspeed

    all do a cat back system for about £300ish

    quite like magnex, but apparently there system for my car makes virtully no noise at all, just as quiet as std.

    so looks like its either jetex or janspeed, so im gonna check there tailpipe options and prices

    I've heard janspeed are loud almost to the point of being uncomfortable, raspy at low revs and boomy but they are the best performance wise guess that figures

    think magnex are supposed to be quite toned down until you boot it

    if you want a rough idea, there's a link below to an mpg of a 206 with a magnex fitted, sounds quite deep to me

    re: best exhaust filter combo for performance on 1.8 sport

    I've got the 1.8 engine but the 125bhp version as opposed to the 115bhp early model. The car was quite nippy when it was standard but I've fitted a K&N panel filter and derestricted the airbox and this was a great improvement. However I've since added a ASCAR stainless steel catback Duplex Quad outlet exhaust and the engines a lot quicker than it was before, revs much easier and picks up much faster on the motorways. Noise is fantastic, a low rumble on tickover very similar to a V8 but a nice roar when booted, not too loud or obtrusive though. Back end looks much better with 4 pipes sticking out of it as well. Only drawback is the cost, at £450ish it ain't cheap but its top quality and is fitted and customised to your requirements.

    Can't recommend it highly enough.
    52 Astra G 1.8, 18" Mille Miglia alloys, 325mm Brembo 4 pot conversion, Coupe leather interior, Raid strut brace, Whiteline rear ARB, Irmscher bits (skirts, Carbon steering wheel, Bonnet extension, M3 mirrors, boot & roof spoiler), Reiger Rear Diffuser & Front Bumper, Koni Adj. dampers, 35/30 Vogtland springs, Duplex quad exit ASCAR stainless exhaust.
