Hi folks. I have a 2008 XB with 85k. I love this car. It's been trouble free, fun and I can carry two golf bags unlike a Mini. Here is where I need some help. My XB has a TRD supercharger on it and I want to upgrade the exhaust system, which looks to be a stock TRD system (anyway that what the exhaust tip is). Any input would be helpful. Thanks...….CJ
Welcome welcome welcome, we would like to see pictures of your supercharged xB, you have something rare, not many out there. I don't like loud exhaust on daily drive cars, so couldn't help you there, but I'm sure someone on this forum has experience with exhaust upgrades.
In my opinion don't think you'll get better mpg with upgraded exhaust. If it did, you won't see the small difference due to you wanting to hear that exhaust with your right foot, lol. Sound and performance since you have a supercharger I can see that. As far as stainless steel, let's see what the exhaust looks like, maybe some "Mother's" polish would help for the time being. That stuff works wonders. Look at the difference in the first picture, left billets not polished, right are.
