JCR Titanium Silenced & Non-Silenced Centre Bypass
#77
I’m really close to pulling the trigger, but can’t make up my mind between a straight center bypass and the bypass with silencers. i have some reading to do. My plan was to do the center bypass and retain oem sides to get more sound and tone but be able to go to quiet mode for neighbors and phone calls. Is this the correct setup? Can I do this with the non silenced center bypass?
can anyone comment on how this compares to Akra? Both titanium, akra the “name brand” is considerably higher priced.

I have produced a quick guide to the volume based on my opinion. dB meters only tell part of the story as they don't consider drone, nasty resonance vibrations etc. Volume 1-10 with totally OEM set up there as a control.
Option 1 - OEM Side Silencers & JCR Titanium Centre Bypass
With this set up, are you're retaining the OEM side silencers the PSE button is still very much in effect even though there are no silencers present in the centre section.
- OEM Side Silencers & OEM Centre (Valves Closed - 1 // Valves Open - 3)
- OEM Side Silencer & JCR Titanium Centre Bypass (Valves Closed - 3 // Valves Open - 5)
Option 2 - OEM Side Silencers & JCR Titanium Silenced Centre Bypass
Adding the silenced version of our titanium bypass will ONLY effect the sound when the valves are closed. The sound is almost identical to OEM with valves closed but with valves open the exhaust gasses still head through open pipe so the sound is the same as the non silenced bypass.
- OEM Side Silencers & OEM Centre (Valves Closed - 1 // Valves Open - 3)
- OEM Side Silencer & JCR Titanium Silenced Centre Bypass (Valves Closed - 2 // Valves Open - 5)
Option 3 - Add JCR Titanium Bolt On Tips
Another option would be to add on our Titanium Bolt-On tips to either of the above two options listed. Our Tips remove the step down found in the OEM tips (presumably present to cut volume) and feature a conical design which further accentuates the tone and volume of the exhaust system installed when at WOT. They also look pretty awesome too!
In terms of the numbers above, I would add 0.25 when adding the tips into the equation during normal low load driving however when at WOT the difference is exaggerated and I would add 0.75 to the numbers.
Summary
In my opinion there is absolutely no drone when running OEM side silencers with either our regular or silenced version of the titanium bypass however the silenced version will give you a near OEM sound level (basically silent) with valves closed.
Akra vs JCR
As for the comparison to the Akrapovic bypass, absolutely no question that their products are top notch quality. Personally, I feel you pay for the name to a certain extent which is reflected in their retail price, however the one major difference (beyond the price difference alone) to the JCR titanium exhaust line is that our products are all designed to be totally modular direct replacement parts for OEM. This means if in the future you wish to further expand your exhaust set up with Tips, Side Silencers, Headers etc then you're not already committed to selecting from just one brand.
If I can be of any more assistance please do not hesitate to ask!

We can ceramic coat no problem, there will be an extra charge applied for the process. We use www.zircotec.com for all our ceramic coatings and will be soon offering options for our tips and other items too

Hey JC. This titanium system is looking/sounding real good. Can you PM me the best RL package deal for the silenced centre bypass, valved side bypasses, and titanium tips ceramic coated in black. Thank you.

To clarify, the video in post #2 is titanium center bypass, valved side deletes, and which headers? The inconel race manifolds, or some other headers?
Can you share dyno results for the different combinations? If they are already out there somewhere, I'm sorry I couldn't find them.
When will the inconel race manifolds be available and are they catless?
