(AA)got muffler here in record time. All ratings(excellent) cause that is how it is. Installation real snap using friends muffler shop. Price a wee bit less than local. Quality "Flowmaster"(A+). My '04 Grand AM GT sounds "BAD TA THA BONE"! No offensive sound, but will definitely be heard as a low, mellow, rumble, parked, & talks to ya real good off the line. When up to speed ya got a low mellow, just right, sound which makes ya sit up just a little more in your seat and smile! YEAH BABY! CRUZ'IN!!!

Flowmaster Original 40 Series Mufflers Reviews


Replaced original

Reviewed By James W (EDMONDS, WA) Reviewed for a 2001 Nissan Frontier —5/10/2018 9:28 AM

I got the pipe diameter and size of the original muffler, then ordered this one based on required size. The original system was stainless and both pipes were in very good shape, so I was looking for a replacement muffler that as not going to break the bank. The vehicle is 18 years old, so the only other parts that I found were CAT-back with both pipes included priced almost 6X the muffler alone. The old muffler was cut out and this one welded in, and the system is good as new.
