[jeepin21]

i run a duncan exhaust with there duncan 440 kit also. it is loud but a stock 400 will be a little quieter and i just have there regular exhaust they now make a quieter one you can get that is 25% quieter with a spark arrester and a turndown. if you dont have the money for the quieter exhaut get the regular with a turndown it directs the exhaust down so it doest seem so loud. they give you deciple levels on there site also.
