Motordyne Shockwave TDX2 Exhaust Install/Review (Pictures&Vids)

It's not too loud IMO with ART pipes, they don't really increase the volume like regular TP's.
With stock cats, i think it will be a pretty respectable system volume-wise. Unless you're on it, it's a quiet exhaust anyway, which allows it to be my daily driver.

I got it directly from Motordyne, give them a call.
The sound I think might might not be that different. The TDX2 has a very nice sound in the 2-3k rpm range, the hfc very slightly takes a small amount of that away at the high pitch end. It really is a minimal difference that I noticed.

I am planning on getting this exhaust system and possibly the ART pipes. If I get the optional HFC (is there an extra cost for these instead of the regular pipes?) do you think I will have an issue with passing emissions in CA? Have you had any issues with emissions testing? I know CA is stricter than most states. Is it worth getting the ART pipes as far as power gaines?

Sorry i didn't see your question earlier.
Yes, ART pipes give power gains similar to test pipes, but they're better than test pipes; test pipes are usually great gains except for the low revs, where it actually loses Vs cats, in the case of the ART pipes, it stops the loss as well as keeping the noise down. You end up with a deeper tone too.
If you've got tailpipe 'sniffers' then you usually won't pass with HFC's, they're a $200 option for new mid pipes from Motordyne.

wow nice write up. thanks for suggesting it in the PM.
Couple things:
doesn't adding the HFC in the midpipes kinda negate having the ART TP? haha
secondly, ever think about tucking the bumper in like those with the HKS do since they're about the same?

The HFC's in *this* case have several advantages which mean they don't wipe out the benefits of the ART pipes.
Firstly, moving the cats away from the engine does help, my tuner confirmed this.
Secondly, they're lower cell count than stock and they're now in a collective area of 6 inches, providing a very low restriction, as i mentioned, only around 2HP difference due to these two points.
Not sure on the bumper tuck, as good as the Whiteline bushing is, it's also bright yellow, i'm not sure how much that will show.
I might take a look at this when summer comes, we'll see
