Welcome to CL.

Try a search for the Dunk mufflers.

As far as pipe sizing and things of that nature check livesc400's true dual exhaust for your 400. You should have some power increase with this. https://www.clublexus.com/forums/sho...hreadid=119544

well, it would probably be close. Your best bet is to get 2.5 or 3 inch piping back from a X-pipe (cut out the middle resonator - or on some cars, middle cat- and have your shop put an crossover there)... then just put your Apex Dunks on... should sound great- You may want to start it up and see if its too loud... if it is, install a resonator on each side- they should do the trick.

MyScRuNmla,

Welcome,
For future reference, could you please type with full words and sentences
and correct spelling? I don't want to sound like a pain but it's very difficult
reading other languages.

Sorry, no advice for whatever problem you asked.

In general removing restrictive systems from cars (intake, exhaust, etc) and replacing them with better flowing/designed parts should free up some horsepower. More in some cases, less in others.

I had them on my car a while back and they were very quiet. I did not have full cat-back piping, but from the axle-back, it was real quiet, you could only really hear it when you hit the gas hard. And even then it still sounded like a luxury car.... but that was for a sc300. I think it might sound a little more rumbly on a 400.
