Quick question....

[Brittany]

We just purchased a 2011 SHO. Looking under the car, it has a cat in the downpipe off of each turbo, then the pipes come into what looks like either another cat or a really small muffler, then right after that what looks like another muffler and then at the back of the car it has a muffler right before each tip. So my question is, what exactly are the 2 other "mufflers" behind the cats? I want to delete the mufflers at the back and if the next two upstream are mufflers i'll delete them too, but wasn't sure if one was another cat and maybe a resonator. I don't want to spend $1500 on a catback for not much power gain and just want to be able to hear the turbo's and heard some videos with the mufflers deleted and it sounds good. Thanks for any help.

The smaller "muffler" closer to the engine is a catalytic converter. It can be removed without causing the check engine light to turn on...but if you have emissions in your state, you probably won't pass anymore. The next one is a resonator to help reduce drone.

Great, thank you!

Just going to remove the 2 at the very back then.

Please try to post a sound clip when this is complete. Curious how it sounds.
