17LexusOwner Posted June 20, 2007 Posted June 20, 2007 I've been hearing about (and hearing) LS400's without their mufflers. I really want to do this to my own LS400 and I am wondering what steps and how much it would cost to do this. Also does the sound change if you take out the CC rather then leaving it in? Thanks.
mc teg Posted June 20, 2007 Posted June 20, 2007 Wondering same thing as you. Can you use 3" inch piping or would that have a negative effect such as power loss?
dcfish Posted June 20, 2007 Posted June 20, 2007 #1 You need a certain amount of backpressure for the low end. 3" is fine if you have forced induction. You really need to research a bit more and ask more specific questions.
SKperformance Posted June 20, 2007 Posted June 20, 2007 There is a very large thread with pics and ideas in it with lots of explanations for the LS.
17LexusOwner Posted June 20, 2007 Author Posted June 20, 2007 Do you mean your thread SK? If not will you post a link to the thread you are talking about? I cannot find it.
Jify Posted June 21, 2007 Posted June 21, 2007 Muffler Delete Mod Enjoy. Slightly different for 1st gens, I had to grind/cut off the back mufflers and then welded on straight pipes + tips.
