Title: Motorbike exhaust on a golf
Post by: Gash on 15 May 2012, 21:27
Ok so im looking at putting a motorbike exhaust on my car (well iv pretty much bought it)

From my memory my 16v system is 55mm in diameter, the bike exhaust is 50mm, will i really need a reducer pipe to connect these seeing as theres only 5mm difference between them, surely can make that up in weld?

Yh, but surely the bike box will be much more restrictive seems as its designed for an engine half (or less) the size of your golf

Bike can will be very restrictive and very loud also if you sleeve down you may get issues with back pressure.

It will be stupid loud as it is not really designed to work on a car.

As en ex novice racer in the 600 supersport class & someone that had to hands on strip down an rebuild the cans on my bikes to adjust the noise for noise testing regulations, a race pipe, is not very restrictive,  they baffle sound by means of a highly perforated tube that is wrapped in exhaust wadding, the tighter the wrap the louder the it will be an vice versa i would advise getting a lightly larger bore, as making up 5mm or 2.5 either side of the flanges will be diffcult. on a bike the length of the rear box will adjust the power delivery, a longer can will allow the power to come in further up the range, a short can will give it to you in a fat short band all at once lower down he revs..... not quite sure how this is going to affect your golf.... i would imagine it will do nothing performance wise at all

after all TVR's use bike cans, my mate at Blueflame exhuasts makes them for some users.......
