Buick Gran Sport 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
TJ.
Excellent. I like it.

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

John
The cat looks solid and high quality, features oem style openings to fit oxygen sensors, also came with a gasket, so there was no need for buying it, got it delivered in two days and installed the same day, it was easy because of direct fit, the check engine light is gone

noticed your “pre-fit” in the name of the part, so did a couple of checks before assembling the cat, but the fit was oem, the converter is very high quality and sounds much better than the stock one, recommend it in tandem with a magnaflow cat back for the best sound and performance

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
Ramus
Works better than the OEM catalytic converter, easy to bolt on, the metal is thicker than on cheap Chinese catalytic converters, overall high quality, great option
Category: Performance Catalytic Converters
Antony
Fair price, high-quality and on-time delivery, I’m satisfied with my purchase
Category: Performance Catalytic Converters
Robert

the cat fits and looks as stated, have it installed professionally, the site says limited lifetime warranty so I hope the cat will last a lifetime
