Mr Squibbs Posted November 23, 2012 Report Share Posted November 23, 2012 Hi Firstly apologies if this has been asked before - did run a search but didn't find anything I think I've read the 330i exhaust will fit the 318i providing a Y pipe is fitted, is this correct? Is there anything in particular I should be looking out for when searching for one? Mines a facelift coupe I appreciate I should have bought a 330i in the first place but with buying a house next year that wasn't really an option at this stage. Hoping the 330 exhaust will give a nice bit of noise? Also, will the twin pipes fit out of the cut out on the rear bumper ok? I've read it's the same on all of them, but it doesn't look big enough to take twin pipes.... Link to comment Share on other sites More sharing options...
Ferg Posted November 23, 2012 Report Share Posted November 23, 2012 Also could anyone confirm if a 330 back box will fit a 320, and more importantly will it sound better, I'll be wedging the flap open of course Link to comment Share on other sites More sharing options...
Wash Posted November 24, 2012 Report Share Posted November 24, 2012 Yeah, you can fit a 330 exhaust to the 318 with a Y pipe since the 330 has 2 pipes in it's exhaust and the 318 has 1 pipe. The sound however will remain pretty much the same. If you want your exhaust to be louder, you'll need an aftermarket exhaust instead. Link to comment Share on other sites More sharing options...
Shabaza Posted November 24, 2012 Report Share Posted November 24, 2012 if you want twin pipe get 328 exhaust as it'll fit without y pipe. If you do golf tee mod it'll sound a bit raspier Link to comment Share on other sites More sharing options...
marc l Posted November 24, 2012 Report Share Posted November 24, 2012 I've done it It doesn't sound any louder tbh maybe slightly. I was thinking of removing the middle section Link to comment Share on other sites More sharing options...
Mr Squibbs Posted November 26, 2012 Author Report Share Posted November 26, 2012 Thanks for all the responses, so is it really worth doing? Whats the golf tee mod? Link to comment Share on other sites More sharing options...
Wash Posted November 26, 2012 Report Share Posted November 26, 2012 It's worth doing for the look since the twin pipes look way better than the single 318 pipe but if you're doing it for the noise then you will probably be disappointed.

Mr Squibbs Posted November 26, 2012 Author Report Share Posted November 26, 2012 Agreed to twin pipes will be a massive improvement, not expecting miracles noise wise, just a little bit better than it is would be good This golf mod sounds intriguing, ran search but cant a post which explains what it is and how you do it Link to comment Share on other sites More sharing options...
Phantom Mark Posted November 27, 2012 Report Share Posted November 27, 2012 Think of the extra weight ? If you just want the look then just fit the tips, if you want the sound then cut out your back box or middle box and replace with a blank pipe and then fit double tips for the look, best of both worlds. You simply would not believe how heavy the double pipe system is front to rear........... autosri and Gaz 2 Link to comment Share on other sites More sharing options...
autosri Posted November 27, 2012 Report Share Posted November 27, 2012 ive just replaced my backbox with straight pipes and like you say mark the box weighs a ton Link to comment Share on other sites More sharing options...
Wash Posted November 27, 2012 Report Share Posted November 27, 2012 (edited) Agreed to twin pipes will be a massive improvement, not expecting miracles noise wise, just a little bit better than it is would be good This golf mod sounds intriguing, ran search but cant a post which explains what it is and how you do it There's a flap in the 330 exhaust which opens at high revs which makes the exhaust louder, the golf tee mod is where you permanently open the flap. Doesn't really make a huge difference so like I said, if you want more/different sound, you need to go for a aftermarket or custom exhaust instead.

Thanks for the advice ive just replaced my backbox with straight pipes and like you say mark the box weighs a ton Thanks for the comment, confirms the above There's a flap in the 330 exhaust which opens at high revs which makes the exhaust louder, the golf tee mod is where you permanently open the flap.

Thank you mate for explaining the golf tee mod, and for the advice. I'll give it some thought in the new year Link to comment Share on other sites More sharing options...
