This full stainless steel exhaust system comes complete with a stamped crossover for a broad torque curve and TIG welded stainless steel straight-through absorption style mufflers. It is dual 2.5-inch with a single turn-down exit under each quarter panel for a stealthy look. Although these systems have been specifically developed for direct fitment with HOOKER™ LS swap components for these applications, they will provide equally beneficial fitment, function, and service life with other non-Hooker LS swap manifolds/headers. Can easily be made to work on non-LS engine-equipped G-bodies through modification of the system inlet tubes, or construction of new ones by a competent fabricator.
Features:
- Each system is supplied with a high-efficiency stamped crossover & high-flow TIG-welded 304 SS absorption mufflers
- OE quality hardware (clamps, hanger rods and rubber isolators) provided to ensure excellent fitment and a leak free installation
- Kits are supplied with turn-down style exits under the rear quarter panels
- Stainless steel straight through designed absorption mufflers for a muscle car sound without the resonance
- Constructed of mandrel bent stainless steel tubing
- *Fits All G-Bodies Except EL Caminos - 118-inch Wheelbase

Seems to have helped
Bought a used 2020 Jeep Sahara 2 liter turbo charged with 80k miles from a dealership. Dealership had just changed oil the day of purchase. Drove it home 30 miles down interstate and another 20 back roads, it ticked and tapped allot at idle and the dip stick was varnished.
I added the flush, let it idle for 10 minutes and drained it. The new oil from the dealership drained out jet black, no light could pass thru it.
I changed the oil with Walmart oil and a cheap oil filter and let it idle for 5 minutes to clean out all the engine flush, it drained out clean and clear.
I refilled it with Pennzoil Platinum High Mileage oil and a Fram Ultra Synthetic oil filter. It's been a week and the engine is noticeably quieter and smoother since using this product.
If nothing else it cleaned allot of carbon from inside of my engine.

HOLY CRAP!!!!
So my 2005 Durango has a 5.7 and I put on 253,000 miles on it before it blew a head gasket. Since it was summer, iI decided I'd tackle it myself. The upper end was so full of gunk, I can't believe I hadn't had serious issues. Anyway, I apparently dropped some pieces of crud down the oil channels, 'cuz after putting it all back together, I got alarms for low oil pressure. Figuring I'd try anything else before replacing the oil pump, i gave this stuff a try. WOW!!!! Not only did the oil pressure return, the engine runs SO much smoother! I had forgotten how smooth it ran when it was new. The caveat is that apparently the gunk was the only thing keeping some areas from leaking - as it lost oil at a startling rate. 1 bottle of the Liqui Oil Saver though, and within a week the oil leaks completely stopped.

Awesome!!
Had a check engine light come on for cam shaft position. Did some research online about the specific code and found that I could be due to sludge in the engine. Added this and ran for about 30 minutes and then had the oil changed.
The light never came back on and the engine is running smooth and quiet.
Will definitely use again.
