5Flowmaster fabulous
By Itburns
Wasn't sure if getting this product for my vehicle would do much on the performance end, but once getting it and having it installed, made a believer out of me. I have a 2000 Chevy S-10 SS pick up truck, which has the 2.2 liter engine. Not a lot of muscle to say the least. I was just looking to get a little better performance out of the small engine. I knew that just by installing a Flowmaster, wouldn't give me big muscle, nor was I looking for a better sound, to make it sound like it has more muscle. I put this 50 series Delta Flow Flowmaster on, and I was actually surprised that it gave my vehicle better performance that I had even hoped for. It now accelerates faster, it has more power on inclines, which before the Flowmaster was a joke. The engine runs smoother, and now seems more efficient at the gas pump as well. As far as the sound, I am glad that it's actually relatively quiet. Not really much louder than the stock muffler. Not that the small 2.2 can produce big sound anyway, but my lawnmower is more noisy. Of course the lawnmower doesn't have a Flowmaster by comparison. I haven't checked my gas mileage since the switch, but from "gauging" the gas gauge, it seems to be getting more miles to the gallon. If I had to guess, I'm getting about 1 1/2 to 2 MPG better.Last but not least, Amazon came through with best price on the internet, and fast, FREE, Shipping! What more can you ask?

Couldn't have been happier with this Flowmaster! I installed it on my 95 Wrangler and noticed an immediate difference in drive.
