FINALLY GOT FLOWMASTERS TODAY!

I love the sound. I went with the 50 series SUV. IT IS bad@ss! I love the sound. Not too loud, but definately very loud. I have a question though. I feel like i lost a lot of low-end torque off of this endeavor. However, it feels like some of it came back later through the night. Almost like my engine adjusted to it. Is this possible, or is it just my imagination? Thanks

I love mine too,,i haven't noticed any change in the sound,,they are loud and throaty........Gun

It is possible that the computer was just adjusting to the change. Another factor is the ambient tempature. Driving under hot conditions will affect the intake air temp. At night the air is cooler thus a lower intake air temp. The colder the air....the more dense it is....giving better combustion.

This may sound odd, but my car's speed/low end torque is back to normal. ####! NOW I HAVE MY QUICK PICKUP AND A LOUD ASS EXHAUST! HOW MUCH BETTER CAN IT GET?!

It WILL get louder, If I remember correctly, within 3000 miles it will get UP TO 15% louder, maybe less.

I don't think you lost low end torque because of the Flowmaster because they usually maintain backpressure, But what size pipes did you go with an what style exit do you have?

Its very possible to lose some low end torque by losing back-backpressure (whether or not you did with your new setup) Youre computer "learns" constantly with every change.. Alot of LS1 Guys I know reset their ECMs by pulling certain fuses.. Ive done this also after unbolting/ and rebolting up my exhaust... It just helps your comp. "learn" quicker....

That's the idle re-learn procedure.

1) Turn ignition key on to "ACC"

In the case of the Camaro/Trans Am go to the underhood electrical center

2) Pull PCM BAT

3) Pull PCM IGN

4) let simmer for a minute or so

5) Turn off ignition

6) Re-insert PCM IGN

7) Re-insert PCM BAT

Some fo the trucks have underhood electrical centers, primarily the newer ones. So this process would work there too. However, on the older trucks, simply turn the ignition on to "ACC" and disconnect the negative terminal of the battery.

Welcome to the Flowmaster family...you made a good choice going with flowmasters...as far as re-learning the computer...I didn't mess with it...the truck idled funny for awhile but then she fixed herself...I just figured she is like any other woman and couldn't make up her mine for awhile... :thumb:
