Finally, discrete power!
I have gone through 3 mufflers to find the right one...the Flowmaster 60 is it.
The 1st muffler was just junk. So, I spent the money to get what I knew was a reputable muffler.
I have a 1990 Integra with a JDM B18A running 2.5" custom exhaust and a high flow cat.
I got talked into a 40 and then a 50 series muffler from flowmaster. They were both high quality, however they are not tuned for a 4 cylinder.
Flowmasters work via destructive interference of exhaust pulses which translate into a low frequency and the chambers in a Flowmaster are tuned to bounce back the sound frequency which is 180 degrees out of phase with the said pulse.
The 40 and 50 series are tuned for an 8 cylinder and do not cancel out the exhaust note because the frequency is not tuned for a 4 cylinder and therefore do not cancel much of the sound.
In fact, they sound terrible with a loud raspy note and a resonation at about 2000 RPM that makes you want to plug your ears.
I was told by several vendors that a 60 series was not available in anything larger than a 2" diameter and the overall dimensions were too large for my application. I went on their word.
Then I found AUTO ANYTHING where the perfect muffler awaited.
It turns out the 60 is smaller and lighter as well as tuned FOR A 4 CYLINDER! I ordered it and received it very quickly.
Unlike the 40 and 50 series, the 60 is black, the others silver, which attracts less attention. The fit is perfect as it is a little larger than 2.25", perfect fit and it sounds great.
I have not been pulled over and it is quiet until you get on the gas and then it is obvious that it is made for a 4 cylinder. No resonation and I could not be happier.
As for the price, AUTOANYTHING beat everyone including SUMMIT racing, known for the prices. Just a side note...I had spoken with SUMMIT on many occasions about what I was looking for and they did not have it...until I gave them a part number.
So much for SUMMITS' customer service.
I have recommended AUTOANYTHING to many fiends
