just a quick review on the shorty gp exhaust that’s on eBay for 60 bucks I installed today on my cbr 600 f4i 2001 letting anyone who’s posted to the forum about wanting to buy one that it’s probaly not a good idea .
Reason being that it’s loud not like loud but god awful loud it damn near blew my eardrums out on the freeway . Besides that the exhaust itself isn’t too bad , easy install , it as a “baffle” but in all honesty it’s literally a pipe . Alittle too close to the rear tire for me . Also it’s not very secure once you tighten it even all the way has it seems to wiggle .
It looks good it sounds okay but it’s just too much for everyday use in my opinion . I’m going to return it soon and I’ve only had it on for about 7 hours .
Hope this helps anyone looking to or considering buying one .
