Re: '14 grand cherokee exhaust thread
As of now, I replaced the stock suitcase muffler with two Flowmaster DBX mufflers(2.25" in/out) and x pipe. I kept the factory resonators. Sounds very good. No drone cruising, fairly quiet at idle and great tone when accelerating. However, the shop did a poor job(I should have taken it to a custom exhaust shop!). There really wasn't enough room for both the mufflers and the x pipe. The mufflers hang down too much and there are some leaks.
I recently bought a borla 11826 SRT axle back exhaust and will have a good custom exhaust shop install this and rebuild everything. The x pipe will be removed and an h pipe created in the narrow area where the pipes run parallel. The "off the shelf" x pipes won't fit in that narrow area.
