There has been some discussion about the discontinuing of our Greddy Go Tuning Unlimited Spectrum Elite 70mm Single and the development of a replacement model. Since the SE 70mm Single was designed off of the SE 70mm Dual it wasn't meant to be a single exhaust so it didn't meet a lot of our expectations. So this time we started from scratch to design an exhaust that would meet our requirements. Our goals were to produce a lightweight and quiet 70mm single exhaust that makes good power with a non-aggressive style. The closest exhaust to this design would be the ASM 70mm single but due to rising exchange rates and production shortages, this exhaust has becoming increasing unavailable to people. We wanted to design something that had all the great features of the ASM but much more so we specified to Greddy every detail of the design starting with the internal layout and structure of the front and rear mufflers; the size, shape, and location of the mufflers; the layout of the piping; the exact location of each component; and the size, shape and design of the tip. We also wanted to retain the subtle Spectrum Elite "sport" look to it vs. something racy and aggressive. In the end, we developed an exhaust that was lightweight, quiet, produces good power, with a clean sporty look, all for about the same price (pricing TBA) as the ASM 70mm Stainless Single.

Current Specs:
70mm Titanium Single
93.5 dB at 5800rpm (stock is 92dB and SE Dual is 94dB)
Weighs ~15 lbs (final production weight may vary)
90mm Tip Diameter (SE Dual/Single 102mm Tip, ASM Single 80mm Tip)
Helmholz Resonator
Custom mufflers
Estimated 10hp gain
Estimated $2000 price point

After several prototypes and some hiccups, we're one step closer to production with the latest prototype that came in. Initial test are mostly positive so stay tuned for updates.

 

Very nice!

Would love to see this thing with a straight tip like the ASM exhausts, and possibly a fully burnt tip like the Amuse exhausts. Would it also be possible to have the muffler more tucked up into the bumper? Seems like it hangs a tad low.

Either way, looking forward to hearing this thing!

 

We opted for a slash cut tip like the SE single because a 90mm straight cut single walled tip only looks good on TiC style turbo exhausts. The tip is centered in the muffer look better like this with this style and size tip. We experimented with a offset muffler but you need a really small tip or else it just looks wrong.

 

Looks awesome!! Any pics on an AP2- style rear bumper?

 

exhaust looks good

 

Coming soon...

 

Can't wait for this! Good job Aaron!

 

double rolled tip. It really finishes the exhaust off nicely

 

I'm excited!!!!

 

Looking good.
