Quality Just OK for the Price!!.
Had to modify one factory manifold nut to get it to go back on by grinding down the outside edge and also bore out the cat bolt holes on one side to get back together. Removing the OEM heat shields took a lot of time and a few words to get out. About 5-1/2 hrs from start to finish. All in all not too bad. They did seem to increase output in the mid range. With the Banks Monster Exhaust and a cold air intake this little puppy moves along really nice. Last addition will be the Bully Dog GT tuner.
I have installed quite a few exhaust systems and the jba system does seem to fit together quite well. At first start up the exhaust has a nice mellow tone to it and mellows out to just slightly louder than stock. When cruising down the road it's a nice deep mellow tone and not over bearing to your ears. My all terrain tires are actually louder. When ya do get on the throttle the exhaust does let you know its there especially in the upper rpm range but not so loud as to kill your ears.
