"Replacing original converter on 98 TJ 92k three speed automatic. Recieved package promptly.Box was beat up with hole in side from head pipe and converter being loose in box. Poor packaging! Items not damaged. Quality of head pipe and converter is very good. Does not come with a doenut head pipe gasket. If replacing gasket,make sure it is small and thin,because the original header bolts are very short! New converter weighs half as much as old one,and is half the size. A plus! Disassembly is easier with a sawsall. If connecting to old muffler,good luck! Old converter support rod can be difficult to pull from the rubber, Good time to replace the muffler/tailpipe. This Magnaflow Direct-Fit proceeds a new cat back system on my Jeep. The noise level increased moderately,and increased throttle response. Very pleased with this system!" —Alan B from Portage, MI bought a Magnaflow Catalytic Converters - 49 State Legal for a 1998 Jeep Wrangler, 4.0L 6-cyl. engine.
