Lexus GS350 2007-2011 AWD underbody Catalytic Converter 3.5L 6 cylinder

Bolted right up works as described. Wish they included new bolts but they did include new nuts.

Straight forward for install and the fitment was on point. I’d highly recommend

JP at Muffler Express was awesome, and helped confirm that these were the right parts. The shop I use put them in with no issues. The car is quiet again. Amazing what you can get used to when something degrades slowly over time. Should have replaced these pipes a while ago. Lexus wanted $2500 for them. No need if you're not under CARB testing (CA, CO, ME and NY). If the mufflers downstream if these pipes go, will definitely buy the replacements from Muffler Express.
