Our first version will be a dual tip setup, and today we played around with sound. Its amazing how quiet the car is with no catback. Fun times to come for sure!

I hope Perrin comes out with a straight back (center exit) race pipe with dual tips (no muffler). You would obviously need a different rear lower fascia/valance (whatever it's called) to make the center single exit pipe look nice. Would be cool if there was a carbon fiber option on the rear lower fascia/valance. This setup without a muffler would save a ton of weight and be an aggressive option for track go-ers.

Please do something amazing with the sound. That's one of the weakest points on the car for me is the lack of a good exhaust note. I am still rocking a Perrin Catback on my Legacy GT that you guys discontinued a long time ago and I still think it's the best sounding exhaust for the LGT. Crackles, burbles, and even pops sometimes, great bass but no drone, perfect volume. Glorious.

Are you referring to a difference in construction? Because as far as the ECU is concerned, the cat in the manifold is the only cat on the car. |

Oh, On-Topic post:
Because the HKS Spec-L specifically is designed for lightness and the manufacturer has stated a weight for it, it is now at the top of my list. Weight matters with this car, so it matters to me more than ever. |

I think the Spec-L will be too loud once you start playing with the headers and cats.
I'd like to see what happens to the power and torque curve removing the secondary cat and fitting a good catback. |

Correct me if I'm wrong but I always thought Catback exhausts replace whatever is behind the catalytic converter but you still would use your original cat...reason for the name catback. Unless your taking about the exhaust companies replacing the original cat with a high-flow cat? I feel like those exhaust would be really pricey...

As there are two cats emission won't be terribile with just the 1st one.
Obviously the best solution is to replace both of them with a 1st grade sport cats, but to just replace the 2nd with a straight pipe is cheap and won't turn on any CEL as it's not monitored. |

That depends on the country...
Usually in Italy the pre-cat is enough to pass emission control, if the car is well warmed up. |
