1995 suzuki intruder 800 tail light works but brake light does not

Hi Lcyr. 
Any changes you make to the exhaust system will alter the sound the bike produces. The more you cut baffles,and open up the exhaust, the louder it will get.  What you do alter to a greater extent,is the state of tune of the motorcycle. Any changes to exhaust or inlet plumbing will require a retune of the engine to suit the modifications. This can be subtle to dramatic. Opening up exhausts can often rob low end power where exhaust port scavaging is relient on some back pressure for maximum effect.
 Best to work directly with an engine tuner to do the mods that are known you can get away with, or buy aftermarket prebuilt pipes that have a known previously tested state of tune. Nothing worse than doing something, that then costs money to put back the way it was on finding out it didnt work as well as was hoped.. Hope this has helped you steer your custom mods a little.  I can say with certainty, that I have ventured to do what you are doing many times in the past, and it has always cost me more money in tuning and... and well more parts :)  Cheers
regards robotek

It mught be the bulb that needs replacing or else check the wiring to the bulb for continuity in case there is a broken or snapped bit.If you have a voltmeter then you can test the voltage reading at the point of contact..Sometimes rust builds up and a simple cleaning would solve this.Hope this helps.

Have you check all the bulbs condition? Check your fuses and the blinker coil.

First, it sounds simple, but do you have the correct bulb with two filaments? Otherwise you should look for a loose wire, or corroded lead.

Make sure that the rear light fuse is not blown
If not trace the brown wire from the rear lights & check for continuity between lamp holder & fuse
As its both rear lights & front sidelights it will not be an earth fault

Hope this helps (if so please mark as very helpful)
