I may as well jump in here.
CVE has been a dealer and using Snort stuff for years now.
A lot of manifold issues can come from the installation process. There are good and bad ways of installing them.
I suppose that is why CVE has a very low cracking rate compared to others.
I have always stated if you deal through a SNORT dealer like CVE you get excellent communication and support, I don't think anyone can say otherwise. We do not charge extra for this, however people rather talk to Snort and complain because he is working and does not take calls.
I have been with SNORT during the days and the phone rings flat out, if it was me I would have someone on the phones while he does the work. I suppose that is why he has a dealer network.
I have sold and sent kits and serviced people all over Australia so location is no issues.
One of the issues here is ( and this is not taking a shot at SNORT nor the competitors ) Snort makes a low cost kit, this is sold to people who may not always understand the complexity of the installation, and the kit may be fitted bad,mistreated or other things. then it is the kit's fault. Where if you get a more detailed kit at a higher price you will also have a lower market share, but the class of purchasers will understand the complexities of said kit. ( that is not taking a shot at the E series people, just a fact )
Yes SNORT has had issues in the past but WE ( SNORT and CVE ) have worked to continuously improve the kits, and it has worked well. The other problem is there are hundreds of SNORT manifolds out there, each version better than the last, so the older ones can ruin it for the newer ones.
Now these are just my opinion, but they are my experiences and feel that some of the newer people should know this.
Oh FYI my mustang has a stainless steel tubular manifold and it not cracked or warped last pass on low boost went 8.20 @173 mph
