We had a leak in our old muffler and it hissed all the time. It is a Hi Performance vehicle anyway so we went ahead and
ordered the Flowmaster Series 40 it has standard openings 2.5 in and 2.5 out. It came in two days. Three days later I had it installed for $25.00 at a small auto shop.
It took all of 20 minuets to complete. It has a very nice idle. Sounds like a sleeping GIANT but when traveling around town or on the highway
it's not LOUD. Just a mellow purr. I love it and gas mileage should be a bonus from this low restriction muffler.
Recommended. All Flowmaster products give long life and great performance.

Form, fit, and function was within all expectations. Very little extra work had to be done to get the unit installed.

Fast shipping great item. Put on the next day I could not wait to put them on. I would put them on a 305 and its sounds mean rummmm rummm

I'm running a 454" powered '71 Corvette that has a high-performance factory cam, a high-rise Edelbrock intake, and a 3310-2 Holley carburetor. Up until now I had a set of stock mufflers on it and it would fall flat on it's face at around 3600 rpm. After installing these 40-Series Flowmasters it blasts up to it's 5500 rpm red line with no signs of exhaust restriction whatsoever. And as I'm also running a heavily-modified TH700R4 the amount of exhaust drone at cruising speeds is very small. For those of you who want a very decent street/strip muffler at an affordable price these 40-Series Flowmasters are the way to go. And with the free shipping they're even better.

I order 2 form my truck. The sound is awsome!!! I was really impress with the shipping. Came in 2 days

I got this for my husband and he says its phenomenal. The shipping was quick which was probably my husband favorite feature! Though he does start his durango for everyone now!!
