I currently have a 2014 Q60s with stolen intakes only currently looking at motordyne shockwave exhaust or tomei expreme. Heard great things about the tomei exhaust even have a couple people I know with it that are shooting flames and getting great numbers . How ever I like dual exhaust but also want the best performance exhaust to available . So any suggestions for setups? Motordyne art pipes+ motordyne shockwave or tomei ti expreme ?

Current setup

 

Even with a tune, don't expect more than 20 hp. And that probably won't happen until you get a hi-flow cat.

 

Yeah I’m not trying to hit any big numbers I just want to open her up with the best possible combination of exhaust parts to get a good sound and tune

 

We suggest an Ark Performance exhaust.

What’s the benefits compared to other options or single exit tomei?

 

IMO, you are overthinking your exhaust decision.
All of them will provide marginal gains without a tune and similar gains with a tune.
They differ in sound, so I would base my opinion more around that.

 

Yup, pretty much what inkogito said.

Go full Motordyne and don't look back.

 

I agree with motordyne always have just I know a lot of people tuned with tomei that are getting great gains from admin tuning.

 

Thanks and yeah I know. when u about to drop 2k for an exhaust over a 900 for a titanium exhaust u start to question a lot

 

FWIW, I went with Fast Intentions RHFC and catback and am happy with it.
