Is it really going to give you much more power or torque? £600+ worth?________________________________________ Nothing to see here |

I don't know why people rave about aftermarket exhaust manifolds...I'm currently running north of 450bhp and I'm using a standard manifold, why the need to change?  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

I'm interested in what it would do for mine, sound wise and power wise eg, bonus would be it removes that craply fire ring joint which my manifold can be modified to do anyway. I can't see many people having one of these but id Be interested to know what gains and sounds eg has Been seen. The one I linked is over £900 I could add a little turbo to my car for that! ________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

Noise could be a factor I suppose, but as for power Rich proved the standard manifold was good enough to flow 540bhp so I can't see it being a benefit. It was also proved that 540bhp was above the limits of the engine capabilities and therefore who knows what the standard manifold is good for until it becomes too much of a restriction?I say its different, noise could be good/bad but as for power, no different.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

It won't be benificial to those of you with boost I doubt but apparently in N/a form the manifold does become restrictive at ~240 Bhp.They may seem expensive but If you've spent that much money to get a N/a engine to that sort of power the exhaust cost is minimal in perspective I guess and will see a decent extra gain for your money. ________________________________________ Ryan |

Yeah, I see the point of maybe thinking about at highly tuned N/A level, I was more commenting about the one that Andy posted and thinking what it would do to the performance of his car.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I say its different, noise could be good/bad but as for power, no different. it can only help though stan. If a 540 bhp engine was running a standard mani and it proved unreliable then surely a mani like that would help it perform better/last longer. after all the insane amount of heat from lots of power needs to dissipate as fast and as quicky as possible. for that price id expect stainless and wtf are those clip things. Id avoid spoox tbh  |

The one with the clips in, I was wondering why thy was also, but the one I linked is even dearer and has no clips. ________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

I dont see how any aftermarket mani would benefit over the sandard, same material just a different shape. I dot think put would make it the complicated shape it is when they could just make it simple and straight like this one. No difference what so ever apart from noise MAYBE________________________________________ cherry p1.....SOLD (regreting this)blaze p2.....why did i buy this SOLD Black p3 |

No benefit over the standard manifold on a standard engine. Only benefit is on N/A engines once you get to 230 bhp or above. Different lengths on the secondaries can have quite an effect on midrange aswell, so im told!________________________________________ 2.1 16v 306 Rallye. |

Im sure rich mentioned he changed the pistons to stop it blowing up, because the ones he was sent wasn't exactly the compression ratio he had wanted. Somehody explained to me that supercharged is like halfway between n/a and boosted engine eg turbo, it's not n/a but it runs more n/a than a turbo in relation to exhaust and back flow eg Is this right? Did you it had a negative effect on midrange? ________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

Yeah im sure he read that the issues at the power were sorted but the reason you dont get them that way is A) they spin up at 100mph Theres no point in the extra for the decrease in realiability________________________________________ Ex- Phase 3 China GTi-6 T-Reg |

all i know is the design of the manifold dramatically effects the power and torque in relation to where it comes and where it peaks off within the rev range. |
