AP Exhaust® XS2157 - Stainless Steel Oval Xlerator Performance Muffler

I pulled them out of the box and they looked just like a flowmaster to me . I have a stock 87 mustang lx 5.0 with stock exhaust up until today .. the mufflers were junk .. so i put these mufflers on with new lx tailpipes and i cant tell their any louder than the factory mufflers . Not at all what i was expecting but its exactly what i wanted .. btw the car does have the factory headers and all 4 converters on it . Im trying to keep it as oem as i can afford !!!!!

I bought this muffler for my 2007 Infiniti G35 coupe. I was worried about how it would sound being such a cheap setup. I had a muffler shop install this muffler as well as delete my resonator and it sounds amazing. A nice low growl at idle, but not too much, then when you really open her up she screams like a banshee. I thought I would have to buy a catback system for over $1,000 to get this kind of sound. I would definitely recommend this muffler to anyone wanting a lower tone with a louder more aggressive sound.

Sent them back and bought different mufflers from TRUCKiD.

Great purchase

Just had the new AP muffler installed. Looks identical to the old muffler. Definitely sounds better. Seems a little loud. Not too bad. Would have liked it to be a little quieter. The old muffler was in bad shape and leaking and very loud. Good budget muffler for a little over $100.00 with shipping. Don’t know how long it will last, hopefully at least a few years.

Muffler worked good and made car quiet again.

Bought this muffler as well as the passenger side one for my 2012 Nissan Altima and it came out great.

I received the muffler very fast & definitely would order parts from here again.

I went to my local exhaust shop and asked them to suggest a muffler for my G35 coupe that would deepen and louden the tone without being obnoxiously loud. He told me about AP Exhaust and how they acquired the patents to all of the Flowmaster Super 40 Series of Mufflers and now sell them under their own brand. So he ended up suggesting the AP Exhaust equivalent of the Super 44. I was skeptical honestly since I had not heard of AP Exhaust and it was a really low cost muffler. To my surprise it sounds amazing! It most definitely sounds like a Flowmaster 40 series, nice and deep and moderately loud. I would definitely recommend AP Exhaust to anyone looking for something along the lines of a Flowmaster/Magnaflow/Borla kind of sound for half the price.

Told the guy at the muffler place I wouldn't mind a deep sound, but I didn't want loud. He apparently only heard the first half of my request. These things are way too loud. I can't hear my radio when going over 30 mph. I've got to find something quieter to replace these things. I don't want to be "that guy" in my neighborhood who everybody curses when I come & go.
