Mercedes-Benz GL550 Performance Exhaust Systems reviews

Matt
This is not magnaflow or borla, but it is worth what it costs, the metal is thick and the muffler itself provides some power boost you can hear and feel, I think it’s hard to find something better for this price
Category: Performance Mufflers
Victor
The tip looks really good but could be thicker because the metal got discolored when I welded it, but still, it looks nice and arrived well-packed in a box, the shipping was fast, no questions at all!
Category: Exhaust Tips
Nolan
I prepared my car for a track, so I replaced my cat with these pipes, I haven’t measured the power boost yet, but they definitely work, I wish they were legal on the street!
Category: Performance Catalytic Converter Pipes

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

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”

The part was on pre-order but since I was looking for an OBDII compliant direct-fit catalytic converter for my Ram I gave it a chance, I got it delivered in 10 days, the part looks durable and quality, fit is also good, I will recommend your website

Rick
Bought the part following your sales rep’s recommendation, the cat came on time and in good condition, looks like a high-quality one, thank you!

Stainless steel construction and accurate fit, it seems to be lighter than my stock cat but the metal is thick and looks good
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
Andrew
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

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!

talked to your sales rep, who recommended the magnaflow catalytic converter for my son’s toyota. The part was delivered in two business days which was a big surprise for me. Thank you, guys! I’m gonna do business with you again!
