    hi there people . when i put my foot down in 2nd or 3rd gear the car sort of drags then a boost kicks in like something blocked as any one any ideas. when i bought the car the guy said it has an m3 downpipe just the pipe . and chipped. it has a cat back stainless steel exhaust. does anyone know how it ca be checked if it has been chipped and if it has got the downpipe.

    Id be suprised if it's got an M3 downpipe mate - it wouldn't fit. the iS goes from 4-2-1 where as the M3 will be 6-2-2.

    Only way to see if it's chipped for sure is to open up the ECU and have a look.

    If i was you i'd get a diagnostic test done it to check if it's running within limits, it could throw up a cam sensor fault or possibly if the ECU is chipped the car could be running rich or to lean.

    ive i had this before and someone said it could just have the pipe which is possible i know what you mean though . ive had an is before 1.8 the m44 engine this one is the m42 engine and i know for sure its quicker than the m44 the fuel dont last that long on it and it struggles to start up first time. i think its the crankshaft through past experiences

    how do you mean it just has the pipe
    if your car has the m3 exhaust i imagine the it would just be the rear section and the backbox as the down pipe wont fit

    the m42 is a 1.8 and was fitted up to 1996 the m44 engine is a 1.9 as fitted from 1996 onwards

    the best thing to do would be to get the car on the computer and have the codes checked it sounds like the camshaft sensor however in some cases it might not throw up a code

    the camshaft sensor will take the lambda sensor with it so i would budget to replace both of these
