Description:
The 70 Series Big Block II™ is designed around a large Flowmaster case for maximum volume and efficiency. The case is also 2 inch narrower than Flowmaster’s original Big Block™ muffler, making for easier installation in tight applications. The 70 Series offers a mild mellow exhaust tone and incorporates a Resonant Tuning Chamber for reduced interior sound levels.

Review 2 of 18

Price Paid:  $125.00 from Napa auto

Strengths:
Deep mellow tone, not too loud. Makes truck sound powerful.

Weaknesses:
Nothing really so far, except for some minor adjustments to the truck while putting it on. As far as sound, it's perfect.

Summary:
I just got my permit, and me and my older brother who is unable to drive, wanted our truck to be louder. This muffler is exactly what kind of sound I wanted.It doesnt crackle when you step on the gas. The tone is a very deep, and mellow tone.The interior noise is hardly noticeable, which is good.

Review 3 of 18

Price Paid:  $140.00 from Summit Racing

Year / Model Reviewed:
2005 Toyota Tacoma

Strengths:
Good deep sound, very minimal drone

Weaknesses:
Price is high for muffler only

Summary:
After purchasing an entire magnaflow cat-back system with the T304 stainless stell pipes, I relaized the muffler was nothing more than an over priced glasspack. The interior resonance (drone) was ridiculous between 1350-1700 RPM, espeicially if the tranny dropped into OD.
Did some research, spoke with Flowmaster Tech support for nearly 30 minutes. After some additional reviews, I decided to purchase. Couldn't be happier with the deep sound, low cab noise, and feel of breathaibility in the exhaust system. If your looking for something on an SUV or truck to get some additional sound and HP- look no further. A couple friends have sworn against flowmaster until they heard this one.

Review 4 of 18

Price Paid:  $119.00 from Jegs

Year / Model Reviewed:
1997 Gmc Yukon

Strengths:
Great mellow sound at idle, but growls pretty good when you accelerate. Nice improvement in horsepower at cruising and passing speeds.

Weaknesses:
Not an easy install to the original tailpipe, had to go have an internal sleeve built to make it fit.

Summary:
Great sound, not overbearing at all in the cab, which is good since this vehicle is used primarily for towing. Definite improvement in h.p. from 2-3k rpm's.
