Time to fess up - I tuned my 650S and added sport cats!

Gents,

After much deliberation, I finally took the plunge and tuned my 650. My objective was likely the same as everybody else's who does this: to grab some of the extra power that is there for the taking on these cars, without compromising reliability, safety, or engine life.

I took the car to BBI in Huntington Beach, CA, which is known for being more of a Porsche & Ferrari tuner. However, I chose them because their work and attention to detail is second to none.

Bottom line is I am astounded with the results and could not be happier. I hope to add some pics that they took shortly. Their sport cats are made out of inconel and look like little jewels compared to the standard cats. Their couplers are completely custom formed and use an inconel flex joint that they originally developed for Indy cars. Easy to reverse as well, using all standard mounting brackets/perches.

I am hoping to put the car on a dyno shortly, but for now I can only confirm that my butt dyno tells me the car is way, way faster and responsive. The midrange punch when the car comes on boost is much stronger. At the low end, I am pretty much traction limited by my tires. However, on 3rd or 4th gear pulls from 60mph on up, the acceleration is mind boggling. The sound is quite manageable when I am just driving around town, but at WOT the car really screams now.

I will post the dyno results when we have them, but in the interim I will also offer that this same shop did cat bypass pipes, a sport exhaust and an ECU flash on my buddy's new 488GTB and they said my 650S was faster than that car. Also interesting to note that the shop tech couldn't get over how much better the build quality was on the Mac.

Just reporting from the trenches boys. Best regards to all.

Thoughts on sound? Been debating on going catless and adding tune from
Vivid. I am on the fence and have the quote ready to go. I've held back due to second guessing the tune and catless downpipes. It pisses me off when my buddy (488) and I go riding and his roars while mine just purrs with oem sport exhaust.

Sound is a little nastier than stock while cruising about.

When I hammer the car and the muffler baffles open, the car really screams. Loud and nasty, but nice if that makes any sense.

Zero resonance at any time, thank god. Resonance is a dealbreaker for me.

I am trying to upload a sound clip, but as of now, the file is too large. Need to enlist my teenage daughter to show the old man how to compress and upload a file. Stay tuned!
