starlybruiser Posted September 2, 2008 Share Posted September 2, 2008 Well i recently spend 370 quid of my hard earned money on a full custom turbo back system from custom exhausts ltd in cardiff, its 2.5" pipe work straight from the turbo the down pipe is braced and it has no silencers apart from the backbox which is a 4" exit. the only thing i have a problem with is the bends, he said he had to use a mandrel bender to bend the pipe work but just before each bend there is an indent? is this normal?? or has he done it wrong? also it doesnt pop as much as i wanted it, the back box was also made there and its got 2.5" pipe through it then a 4" tail pipe, if i had the backbox piping opened up to a larger diameter would it pop more? cheers STARLYBRUISER Quote Link to post Share on other sites

StarletRick Posted September 3, 2008 Share Posted September 3, 2008 properly bend mandrel pipe will have a uniform ID. if it has little indents in it, hes used a crush bender. 99% of exhaust places use them so i wouldnt be surprised. you dont have a mandrel bent exhaust.

WTF this is when my head went F**kin POP, went straight into evil mode and got the owner to ring me, when he did he was nice as pie and said he didnt realise that i asked for mandrel bends throughout, and so when i go there saturday for my decat brace to be fitted he is going to have a look and a chat and see what they can do, so fingers crossed he does them for me, but if he doesnt....................well lets just not say anything till saturday rant officially over till saturday haha, but if he doesnt do anything is there much difference in performance between mandrel bent and crush bent pipes? as he said his bender makes the pipe oval, so instead of being 2.5" straight through on the bends, it is 2.25 by 2.75, so it still has the flow volume as being 2.5"???? sounds like hes trying to fob me off..... big time Cheers STARLYBRUISER .

starlybruiser Posted September 3, 2008 Author Share Posted September 3, 2008 Prospeed FTW yeah isn't it, i wish i went to them now , but the down pipe he done at custom exhaust is truely amazing, its beefy as fuk, got an 8mm flange on it and having brace fitted saturday, just a pitty about the bends in the rest of the system because the back box is actually starting to pop a bit now, so it must need time to bed in, cheers, STARLYBRUISER Quote Link to post Share on other sites
starlybruiser Posted September 6, 2008 Author Share Posted September 6, 2008 well i went back to Custom exhausts today for my bracket to be fitted and to moan like a biach about the bends but he said it would cost megga bucks for the mandrel bends and theres nothing he can do, so i said " well in future i suggest you listen to what your customers actually asked for and give them a correct price to start with" then i left spinning up the starlet kicking gravel up at his windows i know i shouldnt be so harsh but hey i did ask for mandrels , anyway i went around the corner to prospeed exhaust ( FTW sparky ) and what a difference in customer service he was such a nice guy, he got my car on the ramps and said " to be honest you got quite a bargain with that as i would have charged a bit more even for crush bent pipes " he did say he would have done a few bits different but im just glad he said its a good buy and its not that restrictive and the crush bends will give me a bit of back pressure that will help with a small engine. so im happy again now lol just need to get some pics and a vid up now Anyway custom exhaust fitted the top sensor back into the decat but couldnt do the bottom one as he didnt have the materials there to do it, now if i remember rightly isnt this a cat temperature sunsor that just operates a light on the dash if the cat got too hot?? correct me if im wrong ;) cheers STARLYBRUSIER .
