Alright guys, i have a Flowmaster Super 40 that i have sitting around that i havent gotten to install yet, but right now ive got the stock muffler on.. Basically, me and afew of my crazy buddys are throwing around the idea of sawing off my stock muffler and running straightpipes until i finally decide to put the Flowmaster on

Is this a bad idea? if i ran no muffler would my car be redicilously loud or toleratable?

Here is a video of a monte, running no muffler and has the same engine as my car, it dosent seem crazy loud, but sounds pretty ******

Straight pipes are also illegla in some cities/states. Check out your local laws and regulations befor eyou persue this. If you decide you care not, then it's up to you I guess. :confused:

Sometimes strait pipes sound good.. Especially on those new cummins diesels!! Those sound so sick.

Just because he does so, does not mean that they pass emmissions.

he dosent have to pass emissions, his truck is old as anything, back before they even had cats , so its not required on his truck

No...unless you have a blown/cammed V8, turbo'd Supra/350z, or a Ferrari/Lamborghini/etc, nobody wants to hear your exhaust without a muffler.

if you enjoy the smell of exhaust...yes.

after cutting the pipes, it is best to test them by sitting in a closed garage with the motor running.:D

You have to check emissions laws in your state. If you run without a muffler on a car thats past 96 at least in New York there is no chance of ever passing the emissions testing. I have a 94 so I don't need to worry about it

leave the muffler on it, you will be sick of no muffler within a matter of days, or a matter of hours.

thats such a stupid idea...and a great way to spend lots of money on lots of tickets...the only cars that should even be running no headers are full out race cars or those top fuel dragsters

You will likely experience a decrease in performance. Much like taking your intake / airbox off.

Expect rough idle, loss of power, increased gas consumption.

even race cars have sound resrictions keeping them quiet.

I had a set of Hooker headers I had on my Bronco (5.8 V8) and they didn't bolt up right to the exhaust.... so I spent a couple days running around with just headers.... pros: LOUD!!!, sounds cool at idle, gets everyones attention.... cons: I was about ready to pass out from exhaust in cab, gets VERY annoying on the highway, loss of power, killed MPG's, and would have eventually burnt up the valves.... moral of story; you need back-pressure for optimum performance and best gas mileage.... IMO stick with what you got till you get that 40 series on there, I have the 40 on my bronco and i love it!

Think of it as a ported enclosure; There's a reason for that port :)
