I've gone through three exhaust systems in the past 20 years. Two GReddy SP exhausts that both broke after three years. Both SPs had the perforated muffle pipe break off and fall into the muffler, allowing the cubed muffler "stuffing" to escape. The same thing happened to my current GReddy SP2 (all stainless compared to the SP stainless muffler and coated B-pipe) on October 12, 2019. The SP2 was installed in March 2008.

I'm looking for a durable exhaust that will last more than 10 years/200k miles. I like the look of the A'pexi WS and Noir exhausts, but they are made of mild steel with a protective coat (WS has SUS304 stainless muffler). I've been leaning towards the Tanabe Medalion Touring with all SUS304 stainless steel construction.

Has anyone here ever used an exhaust for over 10 years with no problems? If so, what brand/model was it?

 

the tanabe Hyper medalion has been on my car for probably close to 10 years and has held up great.

 

I’ve had the Tanabe medallion on my 92 hatch for about two years and still looks new, minus a few scratches on the bottom. And I love the sound.

 

Maganflow is a full stainless system. Ran one on my daily for 8+ years no signs of rust.

Same experience with the Greddy, blew the guts out after 5 years.
