GMC K2500 Performance Exhaust Systems reviews

Adam H.
I was told to replace the cat because the check engine light was on, bought the magnaflow, it’s not the cheapest one but is stainless steel so should not rust like the one I had, fit was good but had to do some piping work
Category: Performance Catalytic Converters
James Natan
It fits like factory!
Category: Performance Exhaust Mid Pipes
David F.
I’m a DIYer who broke the rusted bolt when trying to take off the old cat, fortunately, it was the only problem I faced, the cat is direct fit and high quality, came with a gasket, you may also need an anti-seize lubricant and new downstream sensor, the old is really hard to remove without breaking
Category: Performance Catalytic Converters
Tony J.
a good quality converter with a direct fit, not sure if it adds power but the sound is better now but maybe because I replaced the muffler as well, no problems during installation… the latter was a headache when installing the previous converter
Category: Performance Catalytic Converters
Big Dan
noticed a small gain in acceleration but the sound is the same, good build quality and a direct fit, I tried different brands on my other vehicles, but magnaflow works the best, will do the trick if you’re looking for a couple of extra “horses”
Category: Performance Catalytic Converters
Antony
Fair price, high-quality and on-time delivery, I’m satisfied with my purchase
Category: Performance Catalytic Converters
Hank
A friend of mine recommended your website to buy a catalytic converter for my Dodge. Shipping was fast and the part came well packed, have it already installed, and everything is fine so far, thank you!
Category: Performance Catalytic Converters
Alex
I bought the cat on this website but then found it cheaper and decided to return it for a refund. Instead, you, guys, offered me a price match, so I got the price difference refunded! Great job and one more loyal customer
Category: Performance Catalytic Converters
Chris
I ordered the wrong part, your sales rep offered to send it back for a replacement, got the right cat the same week, thank you so much!
Category: Performance Catalytic Converters
Barbara
I tried to save a couple of bucks so I purchased the part myself, my mechanic said it was high quality…Mark, thank you for the assistance and discount
Category: Performance Catalytic Converters
Gregory
Ordered a catalytic converter for my 1995 Impreza on your website. The part itself is high quality but came with a dent (it looks like it was damaged while shipped), so I refused the delivery and called your customer support to replace the part. I got a new one in 3 days. Great service! Thank you!
Category: Performance Catalytic Converters
Bill
Bought magnaflow cat for my Ford on truck&gear. Both quality and look are at a high level but I had to work on my piping to make it fit, but it’s okay because the site notes it is a universal one.
