Cool muffler deletion

hello. im looking into muffler deletion for me 98' 740il. how unsafe is it to have the muffers off with no tips? will the emissions leak into the car? or is it possible to cut off the downward tips on the mufflers and weld them back to the pipe? would that suffice? any advice would be appreciated.

Thanks,

to answer the question, a muffler delete is not unsafe at all as long as you keep your turn down. if you just cut them off, i imagine it would cause way too much heat in the rear of your vehicle. you will not have exhaust leaks into the cab of the car unless you have holes in your floor board. i did my muffler delete a while ago and love it. i notched my bumper and have my tips coming out the back.

tips. don't cut your gas tank! use a thin piece of sheet metal or wood to guard the area in front of the gas tank so you don't combust!

Everyone doesn't have welding equipment/experience. Personally, I would NEVER use clamp on tips. Id rather have mine done by a professional that does this for a living than take a chance of needing it up. Ill stick to what I'm good at; engines and body work.

I have no welder bro. I learned everything I know about cars from the internet. i've torn my car apart rewiring the stock amplifier to aftermarket subs and put it back together looking brand new. it takes minutes to learn anything you want to. or like you said yes, you can spend you money on someone else's labor who yes I know from experience, overcharge for measly work, just a word of advice to anyone looking to learn something new and save some serious money.

That being said, how do you do a muffler delete without welding anything?

simple. all you need is two jacks. make sure one is one of these. http://www.lulusoso.com/upload/20120...pport_Jack.jpg First, jack one side up. place the shown jack under the pipe about 6 inches before the muffler. bend. do the same on the other side presto. doing this will also make cutting the mufflers off a lot easier. cut the pipe as close as possible to the muffler with a grinder or even a 10 dollar hack saw. after that, remains two nicely bent down pipes shooting the exhaust right out behind the tires ever so perfectly.

the hardest part is bending the pipes down. a lot of weight is needed. nice plump relatives come in handy for that.

Weld what on, the turn downs? Yes. Turn downs tend to be a bit lounder. The sound bounces off the grown and is a bit louder, imo.
