Allstar Performance can... *UPDATE*

I respectfully disagree. It is an issue and a big one. All Star states that these tubes are direct bolt in OEM replacements. Thus a buyer would have that expectation. The negative reviews of these tubes are widespread. I see your point re race cars. However, people are looking for OEM replacements and are getting screwed. Too many vendors selling them with absence of necessary product knowledge. They state: Chrysler 904. Zero mention of any usage restrictions or fitment.
Its all good, but from experience I can assure that if its an aftermarket part you may have to and more than a few times have to modify to make fit, like it or not that's the reality of it and your either ok with it or your not. I can assure you though that the few people that can't make it work that complain to whatever vendor will have zero effect moving forward because there's far more customers that did make it work or put that part on the appropriate type car with minimal issues.
