Talking (Video)Flowmaster Merge: Before and After

Put comparison clips together so anyone who was on the fence about the merge could hear for themselves how much of a difference it makes.

My review: Overall, the exhaust tone is much more mellow and sounds "toned". There is a bit of rasp, but the mellowness of the rasp is not enough to annoy and you will only hear it when giving it a lot of gas.

I recommend this mod to anyone with a full exhaust F body.. it also gains a bit of power

Video (Nice little pull is around 55 seconds ):

Setup:


Just BARELY fit in the Spohn body mounted torque arm.

Thanks man. The difference is in the amount of rasp you get out of a Y pipe setup. For someone like me, who can't run duals because of the torque arm, it is a great option.

I have been thinking about doing this myself. I have a Kooks y pipe with a 4" outlet. Might do it and go with a 4" bullet type muffler dumped.

Thats cool you have the 4" outlet. The merge on my Kooks ORY was at a 45* angle compared to almost parallel in the Flowmaster. I can feel more power up top and can hear the cam a little better when it is idling.

4" dumped would be nice but LOUD lol.

Looks an sounds pretty good but after the 4" merge what is the pipe size on the muffler and after over the axel? Just looks kinda small but next to 4", lol 3" looks small.

Muffler i believe is 3.5" and all the way to the tips is 3" piping. Used a 4"-3" reducer after the merge.

Thanks man! That's the open loop idle, once it warms up, it goes into closed loop and has a bit more "chop, chop, chop.." to it, which personally I like the open loop sound better

Lol I was pulled over last week for doing a 2nd gear pull. Cop let me go because I knew him. How does the dump sound cruising? Is it a lot of drone? I have a dynomax muffler I'm thinking about dumping off of the Flowmaster merge.

Yea the cop let me go to but not after telling me if he catches me again he will write me a $140 ticket lol and the dump sounds good going though the rpms has a lil rasp around 2600 and at 55 isn't bad but at 70 the drone is pretty bad. bad at 70 to the point where it feels like it drops 15 dbs inside the car if u crack the window lol
