Default Flowmaster 40 Series Cold Start

Heres my "cold start" (car ran for a little bit before i restarted it) for anyone looking to hear the flowmaster 40 series with a high flow DP and res delete.

If I remember correctly it was -10 degrees that day... or around there.

I have a 2008 Silver GXP and looking for new exhaust. You have the best sounding GXP I've heard. I have been listening to exhaust's on 'you tube' and where-ever-else online to find the right note for my GXP. I've had Flowmaster in the past, and I will stick to Flowmaster!!! Thanks for you video!!! I am sold!!!!! HOTTSY

Thank you

Not entirely sure because of the different dimensions they offer, I went to a custom shop and had them do it all in one shot... I didn't catch the part number on the boxes but they are the super 40 series with the 2.75" inlet.

Depending on the outside temperature the drone can be intense at times... once the motor is warm it quiets down moderately enough for normal driving without a headache but above 2300RPM it wakes back up.

Use the super 44s. Buy the mufflers from ebay. 120 a pair shipped. Then get the pipe fabbed from a muffler shop that can mandrel bend.
