hi ive got an 89 f250 with a 302 efi and a five speed singlecab. i know for sure im buying a flowmaster 40 oringal series exhaust. (but any input on what to get would be great!) i want a pretty agressive tone. My truck currently has the 2 cats and a straight pipe from there back. But my question is. HOw much sound different would i get putting the flowmaster after them 2 cats or cutting the second one off and running it with just one? Im realy stuck on what to do. and i cant order the exhaust until i decide. If i cut the cat off its a 3inch inlet and if i leave them both its a 2.25" inlet. Any opinions are much aprcieated! thanks!
This is just my opinion. I have had Flowmaster of various series on different vehicles and I will never buy anything from them again. That hollow tin can sound and drone is not for me.
Having said that, if your set on Flowmaster, get super 40. Also any Flowmaster with the stock cats will be really quiet. I would leave it with the straight pipe after the cats. That sounds good. For the Flowmaster to sound good run a 3 inch single exhaust with a high flow cat. I would get a SIDO muffler for cheater duals, but a single tailpipe is fine too.
thanks for the input! Well i just want more of a performance sound than the raspy sound of the straight pipe.. and i was also thinking about mangaflow. Any input on them?
if you ONLY want sound, put the smallest bullet muffler that you can find into your current setup, after the cat. that will take all the rasp out, and youll be able to hear it. if you want performance and a great sound, cut everything off, get some long tubes, no cats, single 12" bullet.
I just put long tubes with a magnaflow hi-flow cat and a Flowmaster Super 44 on my truck. Single 2.5" pipe. Sounds amazing. I like the Super 44's. If you drive long distances it may get tiresome, but i dont in the Zebra, so I dont mind.
i kind of wanted to keep this a cheap project....around 200 bucks..i can bend and fit all the pipeing myself.. Headers are pretty expensive arent they? and my truck looks like it has some kind of sensor on the first cat? will cutting that off effect how it runs at all?
I think it will come down to what look you like better. If your not doing a full exhaust ie long tubes, x or h pipe remove the cats I don't think it will make a difference.
if you can bend and fit piping, and 200 is your budget, i'd buy a bullet muffler and remove the cats. i just have long tubes, and a y-pipe into a bullet, and its nowhere near the loudest vehicle in my fleet. the bullet will remove the rasp, leave the sound.
