Can you just simply cut out stock mufflers, replace with pipe and be done?

Watching tons of video, reading, searching old posts....Can someone help me out here?

If I want to leave my stock cats and res....Can I really just cut the mufflers off, straight pipe it and it not cause harm to my car? It doesn't mess with the cats or cause fuel issues?

I want more rumble on my daily driver and on a tight budget. Was talking to a T-Bird guy last week and he said you could do this without any long term issues.

Can someone help me out?

Thanks.

He Chris......I did it. It does sound much better. I thought about cutting off the resonator too, I may later--but from inside the car, it does have a nice little grumble, but still quiet enough that you can talk to the passenger. Thanks man. It made a big difference and cost me 12 bucks for 2 Chrome tips and about 15-18 for a couple of pieces of pipe. Thanks again.

Im glad you like it. If I hold my car around 65mph all you can hear inside it is the exhaust.

I'm half tempted to just gut my mufflers, and run pipe straight through them so it looks like I have mufflers but instead I'm running past them. Damned visual inspections!

Just call the resonator a muffler

I never even got around to putting straight pipe or tips on my car after I chopped the muffs! I know, I know, very lazy!

I lucked out though, I made a friend with a shell station! No tail pipe or muffler? No problem!

So I made her semi-presentable and am looking forward to getting to know her better through this wonderful forum!

I did the same thing. Except NJ doesnt care about your exhaust pipe, just what comes out of it.

I love my V8, but I'd love it more if all 8 cylinders worked. (they do now)

I would prefer to leave the stock mufflers on. You can cut the resonators off right at the mufflers. It frees up about 30lbs of weight in the back, and still sounds a little more throatier. I did this on my interceptor with excellent results.

You mean resonator as in 1 and its no where close to the mufflers. I also seriously doubt it is 30 lbs.

That was my first thought, too. Considering a muffler weighs about 15 lbs, I'm guessing that hollow resonator is about 5 lbs.

So maybe he's saying cutting the two rear mufflers off; THAT would be about 30 lbs.

I would be prepared to run exhaust pipe back to the bumper before I just hacked off the mufflers and left it. Carbon monoxcide poisioning!! It will get into your interior if you hack off the mufflers and called it a day. Do it right, save up some coin and buy an ebay special exhaust, that is if it still exists from a few years back that everyone was raving about. You will be better off in the long run and it would be done right.

Well I'm still here, and I've sat in my idling car for more than an hour at a time.

It's nice you never have to drive in stop/n/go traffic. Or drive behind a school bus. Or drive where there's road construction.

Or EVER stop at a stop sign and/or red light

If you've ever driven behind a car with the windows down or with vent on for any extended period of time, you're inhaling far more exhaust fumes than what is managing to seep through the seals/plugs in the unibody. Most irritating part of having the exhaust lopped off before the bumper is loud drone.
