Tristan 338 Report post Posted September 21, 2010 Hi I was wondering how much I would be looking at to replace the single pipe with a dual outlet without modifying the rear bumper? And also will this change the exhaust noise at all? Preferring cheaper options, if possible also advantages and disadvantages of different options. Cheers Tristan Quote Share this post Link to post Share on other sites
AN E30 Fan 1 Report post Posted September 21, 2010 Your best bet is to go to a Muffler shop and talk to them, I have heard great things about these guys - http://www.woolfmufflers.co.nz/ Unless someone else has done the same thing on here I doubt you will have much luck getting a quote.

thorburn 121 Report post Posted September 23, 2010 (edited) Are you sure this is right? http://www.aa.co.nz/motoring/tips/ask-jack...d-no-spare.aspx AA could be wrong. I've been through a few warrents with no spare tyre in the boot. I could have been lucky. While it may look nice there isn't really a need for quad pipes on a 325 Opt for the 335i ... or are you talking about just changing the tip?

If you have a spare it must be located correctly, have enough tread etc.. I could be wrong but no spare, no problem. Quote Share this post Link to post Share on other sites
bmpower 3 Report post Posted September 29, 2010 Pretty sure the only requirement for a wof regarding the spare is that if there is a spare wheel, it must be secure. Quote Share this post Link to post Share on other sites
