I'm deciding to get a back box for my march. I've found 3, janspeed, ashley and sportex. Do u guys recommend any over the other? or it does really make a difference?
Just got a sportex s3, quality seems great, seems as good as the janspeed, which unfortunatly rusted and snapped!! doesanyone reccomend a high temprature resistant anti corrision spray i could use on my exhaust before i fit it?
janspeed sell direct on ebay got full system ( not manifold ) for £100 delivered
cheaper than most places for the back box alone mufflerdougs is the name they use.
system sounds nice not very loud though and makes the engine breath a little easier and rev a little free'er but dont think it adds much power but i think its good for the money.
