Performance Exhaust

[Lexonroids]

OK guys next thing on my Lex. I want to do the exhaust on my truck I do plan on doing the SC this year but am going to go ahead with the performance exhaust now. What can I run or better yet who makes one. I have a Borla on my Disco and would like to go the same route on the LEX. I am having trouble finding info on this though.

MAF has/had a nice 3" mandrel bent ceramic coated exhaust, I think that you have to convert to single cat instead of dual cat though. HTH.

We ditched the muffler that came with this and used a large Flowmaster 70 series:

We also went to one Dynatech cat:

We did some custom cutting and welding to bring the whole exhaust tight up under the body.

This along with the headers was still a little on the loud side when on the freeway so we added a baffle/silencer from Jegs after the cat. Louder than stock, but now not annoyingly so.

Jamisobe, so you replaced the OEM cat with Dynatech? Do you still remember the part #? Im interested.Also so you just have one of the Dynatech cat instead of two? I mean the landcruiser had two cats.

I used the one with a 3" inlet and outlet to fit my custom 3" exhaust. If you are looking to keep your stock system then you will have to choose one with a smaller diameter. You will have to find a very good exhaust person who will work with you on adjusting your system. Not just anyone can or will want to dive into your project.
