Snoop's Take

The A-Premium Left Engine Exhaust Manifold Kit is designed specifically for Ford Mustang models from 1999 to 2004, making it a reliable aftermarket replacement option for drivers looking to maintain their vehicle's performance. This kit includes essential components such as the exhaust manifold, gasket, studs, nuts, and washers, all crafted from premium stainless steel to ensure durability and effective noise reduction. Consumer sentiment surrounding this product has been largely positive, particularly highlighting its affordability and satisfactory performance. Many users appreciate the value, stating, "Half the price of the popular auto parts stores," while others noted the quality of customer service, with one reviewer mentioning, "Gotta say, their service was great: they were patient, and the shipping was faster than expected." However, some concerns have been raised about fitment issues and long-term durability, with comments like, "The bigger risk with the cheap ones is probably less about the construction and more about whether it fits up properly with your exhaust." Overall, the A-Premium Left Engine Exhaust Manifold Kit is recommended for those seeking an affordable replacement part for their Ford Mustang. While there are some concerns about durability and fitment, the positive feedback regarding customer service and value makes it a worthwhile consideration in the aftermarket parts category.

Key strengths users can’t stop talking about.
Affordable alternative without issues
I'm 10 months into one without an issue.

I definitely don’t feel that “push you in the seat” acceleration.
has anyone heard of them and what are you experience with them are they cheaply made any known defects?
Good customer service and fast shipping
Gotta say, their service was great: they were patient, and the shipping was faster than expected.
Affordable aftermarket replacement

Where it needs some work!

Areas to watch—feedback on possible improvements.
Concerns about fitment with exhaust
The bigger risk with the cheap ones is probably less about the construction and more about whether it fits up properly with your exhaust.
A leak could cause decreased boost.
PSA: If you haven't already heard, Ford discontinued the OEM intake manifolds.
Concerns about the durability of aftermarket parts
There is a reason why the aftermarket is so cheap. You'll be replacing in a year, again.
