They're all illegal, everywhere, if you want to be technical about it.

Might get flamed, but it is what it is... a moral and legal issue.

Unfortunately, these mods also void a manufacturer's warranty.

Until federal emissions standards are met when modding... we at risk.

The Zen Ti axle back is brilliantly executed and a work of art.

The Nameless mid & Y are beautiful and well-built.

The sound of the cat back as a whole is quiet and docile at idle and through the lower rev range.

The exhaust note is deep & authoritative without being annoying at speed.

More noticeable turbo spooling sound.

No drone at all at any speed or in any gear, with cruise on or with cruise off.

Get on it at full throttle and the exhaust note sounds like that of a Porsche.

Very pleased with this combination & feel it was a great investment.

GrimmSpeed adapter is not necessary with the Nameless mid-pipe.

5 GrimmSpeed hangers enhance exhaust stability & positioning. No NVH !
Any chance of you uploading some revs at different RPM's and possibly a drive by?

Happy to hear you enjoy your setup!

pffft.... thought this was America...

Morals? What do you say when you see a dump truck blowing black smoke from it's stacks. If a downpipe is immoral. The dump truck owner should receive the electric chair.

J pipes are different too. Cobb, Invidia (and others) only have a 100 cell Cat. Grimspeed has a 300 cell Cat with no stink in cabin (for me GS>Q300).

1) For those of you with exhaust systems, did you do a full Turboback or a catback with a separate downpipe? Which brand did you go with?

2) Catted or non Catted?

3) Resonated or non resonated?

Thanks in advance!
2016 sti muffler resonator delete. Sounds amazing
