Flowmaster 70 Series Big Block II Mufflers Reviews


The Yukon XL hums

Reviewed By Joe S (Boulder, CO) Reviewed for a 2001 GMC Yukon XL —2/3/2010 1:47 PM

Wanted to spruce of the old rig, 2001 GMC Yukon Denali XL, so asked a lot of car guys for advise. The 70 Series seemed to be the choice. The XL is the family car and not a muscle car. Autoeverything price can't be beat. Meineke did an install for $50 as it was essentially a swap. They needed to flute the pipes a bit as stock is 2 5/8 and 70 Series are 2 1/4. Dual in, dual out into a Y with a single exhaust. Experts appear split on benefits of dual exhaust, bigger sound, maybe little power boost. Dual exhaust pipes would have cost another $300 or so. Sounds great and heads turn, but inside the rumble is pleasant. A bigger sound might be great at first, but conversation in the car would suffer. Kept the factory pipes, single outlet. I love starting up the Yukon and I feel the extra power for sure. I can really feel the power on climbs. Also put in an oversized K&N airfilter.

Ease of installation, sound and the added performance it gives to the vehicle. Added a cold air intake system from Airaid to allow better air flow to the motor and the Flowmaster for out of the motor, along with the sound. All items were purchased through Anything Auto . Excellent prices, delivery and service from the sales staff.

Great fit and sounds great on my truck... All I need now is a K&N.
