    I have this on my vts mate, what do you mean unusual noises?

    Is this the 4-1 mild steel?

    thats a bit close for my liking on your oil cooler pipes

    glad mine went bust and bought a mocal front mounted one to get rid of that peice of shit

    yeah i got told 4-1s are better suited for VTS and 4-2-1 for vtr being better at low end

    tbh if i get the group buy going on the GMC manifolds ill probablies get one, actually a think i will get one

    As if gmc are going to start giving out discounts lol

    NO the vtr dies out around 4-5k where as the vts comes on cam then therefore the 4-1 is better than the 4-2-1 for the vtr as its top end power.

    Its stainless and yeah i also thought its rather close to the oil cooler pipes!

    But as the noises go its squeaking (prob from the cone) very loud!!! and also on decelerating above 4k it sounds like it vibrating on something (prob oil pipes!)

    Re-routed it up the back of the engine, just about got enough length on the wires!


    4-1 is definatly the way to go on the vts, its actually a bit better low down than before and as soon as you hit 4k it takes off!

    Apart from that touching that pipe it fitted pretty much perfect. Seems to be my luck with exhausts.

    And yeah its stainless, i should bloody well hope so for 265 quid!

    i took all the heat sheilds off my vtr and all was fine, until the car went up in flames! lol

    just take it off matey, glad you never got me to fit it now lol

    by the way, it never went on fire because i took the heat sheild off lol

    just fitted a raceland manifold to the vts and had a few probs with that, was a right clark on, some of the nuts would not go on due to the bends of the manifold being so close to the ends of the studs. so i had to wiggle it around to get the nuts on, then i had to remove the alternator to get access to the nuts on the bottom of the manifold. ended up putting a small hole in the radiator when i tried to pull the old manifold out, got that sorted lol

    the manifold seems to be blowing from the manifold/decat joint. the floating joint on the manifold has nuts welded to it, the standard springs will not fit behind this, ie i had to chop a coil off the spring as to get the washer and the nut on.

    other than that it seems to pull alot better and feels alot smoother when driving around. it does sound different after 3.5 - 4k, a bit tinny. not sure if thats just the de-cat as i have found these always make a raspy noise on all the cars ive fitted them too.

    really impressed with the manifold tho, makes even more bangs, pops and flames now lol

    Not all GMC manifolds are just steel, they do a stainless steel 8v.

    As for them being made by Piper, this is something new to me. I thought they were all BTB, hence them being 'GMC BTB Manifolds' on their site. Unless Piper are BTB?!

    I'd definately call up mate, but they're not a Mickey Mouse company.

    I know they do the gmc btb manifolds, but im sure ive heard they are the same as the piper manifolds, that would explain why its got piper stamped on it...

    not sure if its true, but i would of contacted them before you go saying you have been done...

    You say you have re routed the sensor up the back of the engine what do you mean by that? Re routed it to where?

    The wiring mate, the sensor hole is right at the bottom of the mani yes?
    So the wiring just goes up the back of the engine instead of the front

    lol not taking it off like, not now! paid £57 to get it fitted, manic motors going to have another look at it! they had to drill it and shit! but its on! and believe me you am not taking it off! They going to try sort something with the centre silencer if no good, then going to get a centre pipe with no silencer in it, that will sort it out, its only just touching and there is no screw holding my heat shield up in that one part! if there was and plaed with the centre pipe a bit be all sorted, also i noticed that with manifold on it moved exhaust system to the passenger side slightley.

    My suggestion would be to heat it up and bend it slightley!

    Yes its right at the bottom of the standard manifold, on the gmc 4-1 there isnt a hole so there is no where for the sensor to go right?

    Thats why most fit a sleeve.

    What do you mean the wiring goes up the back, to where?

    GMC do 2 different 4-1 manifolds, a piper and BTB, they currently have no BTB manifolds in stock as far as i know, there awaiting delivery, the one you have is a piper.
