Had a straight pipe on my car but forced the luxury out and with it being a Volvo I couldn't stay with that so I purchased this muffler to give me some tone but bring back the luxury and that's exactly what it did very happy with the end result

I am building a Subaru and put a very custom free flow duel tip "straight thur" muffler on it. It greatly improved performance, but was too loud for me. The Hushpower was the perfect "reasonator" for it. It is compact and you have many options of where to install it. The sound is mellow and just was I wanted! I can't say enought good things about it, great design and super well made.

What is the difference between standard 304 and standard 409 grade stainless? I notice there is a $40 difference between them. Can they be polished to bright?
Answered by Michael K. — Apr 17, 2012 4:41 PM
Hi Tom, the numbers represent the different components the steel is made up of, and therefore the grade. 409 is a lower grade than the 304, meaning it is more susceptible to corrosion. It is commonly held among enthusiasts that 304 is the best for exhaust systems; however, 409 grade is still of much higher quality than aluminized or mild steel. And yes, both grades can be polished.flag Accept Answer

I am looking at the hushpower with 2x2 inlet and outlet. What is the differnce between standard and short?
Answered by Michael K. — Feb 17, 2012 8:54 AM
Hi Larry, the mufflers are essentially the same; however, the standard size measures 18" long and the shorty is 12" long. The one you choose depends on your vehicle's exhaust configuration.flag Accept Answer
