If there is a Borla rep on this forum. I need your assistance, I ordered a NPP catback since January and still have not received the parts from your vendor. The vendor keeps telling me that Borla is backlogged and having issues with NPP. Please PM me so I can provide the details of my order and the vendor info., because its been 5 months.

 

There is a borla rep on here, but why not just write or better, call them? It's easy.

 

I will call them its afterhours at the moment..SMH.

 

Its true.

Also a vendor and haven't been able to get my hands on certain axle backs with NPP..

-Josh

 

I do have some NPP exhausts available

-Josh

 

So you have some customers in the same situation that i'm in....over 5 months waiting?

 

So I contacted borla regarding the backorder. Their rep told me that they were redesigning the NPP exhaust system and it wont be ready until next month-for me this will be 6 months....insane wait. My vendor has been telling me that it would be ready next week for the last 3 months. This may be the last Borla product I ever purchase.

 

Sorry I didn't find this sooner, please contact me directly at davidb@borla.com and I'll personally make sure the issue is resolved to your satisfaction.

To other forum members, please hold on to my email address should you need it in the future.

 

Can you offer and explanation to the rest of us? Some of us have inquiring minds....

 

Finally have received a response regarding this after a few threads and several months. Mr. Borla I sent you an email, I have also communicated with the vendor marylandspeed on this, this is the other thread on the forum:https://www.corvetteforum.com/forums...ver-again.html.

 

We've been doing our due diligence on valve strategy.

Many valves and actuators for NPP and AFM had been failing on the original exhaust systems from the GM factory and since the original valves and actuators were failing it was likely aftermarket valves would fail as well.

It was actually the Camaro that caused us to call a timeout on all GM systems with valves. For one thing, we needed to further test our own valves but we also needed GM to sort out their own issues so we could eliminate them as variable- https://www.torquenews.com/3768/why-...r-rattle-sound

The C7 being the first base Corvette model to integrate exhaust valves for both AFM and NPP created all sorts of problems for GM and as a result for the aftermarket as well. We had to work our way thorough it and we weren't going to ship you guys parts we weren't sure of.

Since we supply GM we have access to GM engineers and we worked with them as part of this process. As they were learning, so were we and we tested and retested our valves based on the data we were getting from them to recreate real driving conditions so we could understand why there were so many issues with the active exhaust.

Short story is, we're through it now and shipping as normal with a valve strategy we're confident in.

If you have any further questions or just want to discuss this with me directly please send me an email at davidb@borla.com

 

The email I sent was titled "8 month wait still no exhaust".

 

Say uma, does what David Borla of Borla Corp. wrote in Post #11 make sense to you?

It does to me. The C7 has some unique aspects to its exhaust that didn't exist in the C6 gen. Things began to fail in the exhaust. GM wanted to fix it. Borla wanted to fix it especially since THEIR product is based on or works with the OEM exhaust. Now, it is fixed. Therefore, now Borla can, and is shipping aftermarket exhausts.

End of story. What would you like from Borla besides an exhaust?

 

The issue is not the fix for the exhaust, it's that Borla never contacted me after I asked for help from a rep. This thread is several months old and that I ordered this exhaust 8 months ago....BTW I still don't have it. A few of the forum members got their exhausts, I have not. I did contact Borla several times and they told me that it would ship out next week more than 5 months ago. My vendor told me they would ship out next week, every week for 7 months.

 

Nothing worse from a companies perspective to say you are going to help a customer then don't. Apparently they did not.

 

I realize the wait was extremely long, but I was a victim of the GM AFM valve issue and I would have rather waited for it to be 'right' before taking my exhaust on and off no less than 4 times. Especially bad if you were paying a shop to do it.

My final solution was buying AFM delete modules from a Forum member to allow me to use the Borla S type exhaust NPP. Borla's valves wouldn't allow the AFMs to relearn (GM procedure) after AFMs were replaced by GM for failing, which was throwing a CEL. I had to put stock cat-back on for the AFMs to relearn and remove the CEL, THEN re-install the Borla exhaust with the AFM delete modules installed.

Borla customer service was VERY good and offered to send me new over the axle pipes without valves if I wanted to try them. I'm running with the valves in the pipes, but chassis control module only talks to the AFM delete module and no CEL. Borla sounds better than any other exhaust IMO, so you will be happy once you hear it. Good luck!

The only confusing part is your car is a Z06 and doesn't have AFM valves in the exhaust, so Borla shouldn't have to change anything for your model C7. Maybe there is something I'm missing.

 

The thing is they never shipped anything, never contacted me, never offered options and told me that they would ship it almost every week for 8 months. I know the exhaust has issues, but someone help me out. Per the request of Mr. Borla I emailed him, I am still waiting for a response.
