anybody got a pic of...

was gonna get a janspeed but i think there to small!
heres a couple more....

out of interest, is there any performance gain from doing this? as in would 2.5" piping with a 4" tip perform any differently to 2.5" piping with a 2.5" ID tip? im guessing not but exhausts seem to be affected alot by fairly minor things, like with the 2.25"/2.5" down pipe etc, would it keep the gas speed up and create a scavenging affect by keeping the speed up and needing to "fill" the gap left, therefore speeding up the rest of the systems flow or does it have a negligable affect on it all?
no gain, you need bigger pipes further back, as there the ones chokeing the air flow. i think

im thinking 2.5" cat back though, would the tip actually make a difference, inside the back box is going to be quite a large area were the gas is largely free to move around, so surely a smaller tip would basically suck the air out of the backbox? not sure if this is going to make sense to anybody, might be the cider
sorry m8, didnt read the above properly, i believe there is some gain however its worth gettin a full system done.
i dont think a smaller tip would do wht i think your saying, i think i would proberly choke the air flow and slow it down. kinda like a mouse and a slack butted hooker farting next to each other poor descri[tion

wouldnt the fact that the piping and tip are the same diameter mean it doesnt slow it down though? although the back box will slow the flow down a bit, but then if this kept it up the would it balance out.
tbh im probably talking crap, i never was much good at physics, learnt what the textbook said and got by without actually understanding much of it :lol:
like the description though, strange images in my head :lol:
fook knows m8 i just ruined my car my sanding down the bubblng arches and respraying them. however i am very happy with my new jdm grill

i like the raspyness ill get a vid up when its done, getting the manifold, downpipe and de cat put on tomorrow because they wont touch other people's parts! so with all that on then the new centre pipe and backbox its gonna be well raspy i hope its not to loud tho! sussex gti i think that looks nice, not to big!
