40 Series Muffler MSRP: $
Loading Please Wait...


Description:
The most aggressive-sounding street and strip muffler in the Flowmaster product line. The 40 Series generates a powerful, aggressive sound outside the vehicle. If you are looking for the traditional Flowmaster sound, the 40 Series offers more of it than any other muffler. The 40 Series generates interior resonance within the vehicle as well, so if you want to really hear your exhaust system inside the vehicle as well as outside it, the 40 Series is for you.
- Off Road/Race applications
- Early and Late-model street/strip vehicles with or without catalytic convertersVehicles with dual exhaust

Review 1 of 145

Price Paid:  $100.00 from Local tire/muffler s

Year / Model Reviewed:
2011 40 series

Strengths:
Low, deep rumble at idle, comes alive when you punch it

Weaknesses:
None so far

Summary:
I was worried it might make my little 1.8L, 4 cyl sound ricer. Most hyundai people use Magnaflow. A friend with a tire shop offered it for $100 installed. An offer I couldn't refuse, and am I ever glad I didn't. It no has the perfect tone for me, a low rumble at idle, a more aggressive, louder sound when you want it to. Makes my little Elantra Coupe sound & feel a little more like the sports car it wants to be. Best $100 mod I've ever done

Similar Products Used:

Review 2 of 145

Price Paid:  $0.00

Year / Model Reviewed:
2001 Ram 2500

Strengths:
None

Weaknesses:
Interior drone, bad sound outside

Summary:
I bought a 40 series single in/dual out muffler for my ram 2500 5.9l v8. I hate it. The interior drone is unbearable. I can hardly hear myself think, let alone try to have a conversation with a friend. The exterior noise is not nice sounding. It made my v8 sound like a v6. It sounds very hollow, not a nice deep tone.

Review 4 of 145

Price Paid:  $160.00 from Sandhills Parts &Ser

Year / Model Reviewed:
2009 Dodge Ram 1500 Crew Cab

Strengths:
Muffler increases the sound level of my exhaust dramatically. It also improved my mpg. You definitely know when I'm coming your way now. My truck sounds like a true BEAST now.

Weaknesses:
None noticed

Summary:
I am really pleased with this system. I was pleased from the first time I turned the key. If a person wants that true deep rumble, it is found in the 40 series.
