Any exhaust that puts the cats next to the turbos and uses muffled chambers will not sounds as "exotic" or "high pitched" as another exhaust with no cats.

There is one option for those that need to keep cats: SpeedTech does the best custom exhausts and can make you an exhaust that moves the cats away from the turbos - put them where the muffler usually is and so the cats act as mufflers. This dramatically changes tone, pitch (they are much higher) and another benefit is keeping EGTs a little lower since the cats arent right next to the turbos.

John at SpeedTech made me one like this that also included a valve to dump off the turbos (routed to avoid cats) so i just push a button on my remote and in a half second the valve opens or closes. Yes it is very loud and sounds pretty bad with the valve open but it is a lot faster obviously. Daily driving valve closed it is much more exotic than any other exhaust because the design is vastly different of course.

John is incredible to work with. Class act. Couldn't be happier for an exhaust that does everything.

You won't have a problem going with a high flow cat like a 200 cell catalytic converter. No CEL's.

Here is my set up

Costa, here's an option to consider. I have a slightly used 2.5 center muffler delete for OEM tips the came off my car when I went to the full 3" x-pipe with the GT2RS style valve dump. It is exactly what you are asking for, i.e. a very slight tweak to the OEM sound, no drone, no CEL.

The same 2.5 pipe with HJS cats results in a little more pronounced sound (which you say you do not desire), but still on the quieter side overall with absolutely no drone and guaranteed no CEL, either.

I can package it either way (with or without cats), but based on your comments, you don't want louder, so the center delete alone, using OEM cats seems like it would be more suited to your goals. If you want to take a look at it, text me and I can show you. It's sitting on a shelf at the factory.

that sounds great John. I will text you.

And being used, if you like it, it's a great opportunity to save some money while sliding down the slippery slope :-)

Hello all,
as for kline, is Inconel worth the extra price over SS, or is sound almost similar. I read just a but higher pitched but is this worth 2x price of SS ?
thanks

If you'd like to send me a note I would be happy to get a bunch of Kline vids over to you to check out. Most of the awesome sound and Jekyll Hyde personality comes from teh exhaust design itself. There are many sound levels and cat options. Inconel just takes it to teh next level
