Sound good so enjoy them when you get them. By the way what were the torque numbers that they sent you . Just wondering what the before and after numbers are. Would be good info for the form.

You'll be very pleased with the Larini setup. I had the decat and exhaust on my Evora and it rocked. Would buy the brand again. Thinking of the decats for the Rapide.

When you mentioned the "decats", you mean the non resonator center section? I am very excited to get this set up...

On the Evora there is a 2nd cat that is passive. It is not monitored by the car; that is what I replaced.

Thanks

Impossible to know but I'd guess the GTE and SPORTS center section. I was told by Larini that the CLUB SPORTS center section is much louder since it eliminates the center resonator.

Bet that thing has a hideous drone at speed. Really difficult to built an exhaust that sounds good without any drone. My Helmholtz resonators got rid of most of it but it's still there.

This was mine before adding the resonators.


I have a bunch of pics in my build thread of making mine. Fun project.

I am still on the fence to either get the center section with the resonator or just straight pipe. I would think the straight pipe center section would yield more HP gains. That along with a Dyno tune. I will have to see since its a daily driver.

I would look into a better flowing set of cats. The factory //R muffler sounds good once some pressure pulses get to it. Being Cali might make that more difficult. I'm running a pair of stock 2010 5.0 Mustang cats in mine and they are an order of magnitude quieter versus the 200 cell cats I had on it.

Looks like they do great prep work there Cambo. Wish our tracks in California were nice and shiny like that.

I have 200 cel cat, x pipe , stock back box. It was too loud so I added 2 cherry bomb resonators and now I think it's perfect this is with fuse 19 in place

Honestly our factory center section are not restrictive and they do work as an hpipe with gases free to travel to the other side. I tested restriction with a monometer and found very little restriction

Same here. There is no way I could launch as hard as that on our local track. I get a lot less wheel spin on a normal road.
