Title: exhaust build
Post by: jamie16v on 26 June 2010, 12:00

i am looking to make up an exhaust up out of different parts to gain a free flowing exhaust on a budget.
i have been looking on ebay and come across what i think is the same peice of pipe at very different prices so i have contacted one seller to ask for the diameter of the pipe.
the first pipe is a sportex item at around £50 posted and the second is a diesel part at about £20 posted..
am i right in thinking that they are basically the same part but one is painted black and has sport written all over it?..
here are the links.

i know, will be looking at them too, i dont have a tube bender though so will have to buy their bends which i dont really want so might just go for one of these ready made pipes anyway but for the rest of the exhaust they will be o.k

right, while funds are low i am going to be making my own decat by chopping out the platanium from a standard cat and welding it back up, so, if anyone happens to have one for a 1.8t laying about let us know (really need one).
i am also going to bypass the centre box with a diesel pipe and keep the standard back box for now.

Im not sure actually thought the upgrade pipe would be 2.5inch, if not I may buy one...

i asked the guy selling the bypass pipe (diesel middle pipe, no box) and he said it was 2" O/D so i think it should be a straight fit, as for the sportex pipe im not sure.
i think the standard cat is 2" too. it should flow a bit better once i cut out the inners.

just get a lenth of pipe from your local motor factors, chop out the cat and the middle box and weld the strait pipe in, thats how mine is done with a standard back box as i didnt want any noise.
for the price of the decat your looking at you will get a lenth of pipe and if your handy with the welder shouldnt cost no more than £10.
mine was already done when i got the car i just had to weld it properly :rolleyes:
