HOW LOUD is the car? - PeachParts Mercedes-Benz Forum

'85 300D

when the majority of the exhaust system is removed? I was wondering if it would be bearbale to run the car briefly in my garage with the exhauts consisting of a few inches of pipe beyond the down pipe.....Just curious. The car is on jackstands but I'd like to run it....I'll prolly just jury rig some canorpis of an exhaust for my inmediate purposes....

It is by no means ear-splitting loud. It will just vibrate the pictures off the wall.

As long as you don't revv it to 5000rpm, it should be bearable for a little while. I have run my car(s) without an exhaust system for 2 years now without any formal complaints from anyone. All I have is a 90* turn after the coupling to get the exhaust soot from the underbody. People say it would be too loud and annoying after a time, but I love it! It can be a bit much of a drone on long trips but thats what a radio is for!

When my muffler/resonators finally rust out (they're well on their way) I am going with no resonators and a flowmaster, I want to achieve a deep "rumble" if I can....something cummins-like.

I bet they'd love me around campus at school......and in our neighborhood here....

You want a stright though muffle with a turbo....the flowmasters have baffles (well sort of) which you don't want...but I'm with you...if I ever get the cash for a TIG and learn to use it I want to weld up a 3" turbo back system...no resonator and straight through muffler.

You can do it with a mig welder for far less.

yeah..but I don't have one of those either...A Tig leaves you the cleanest looking welds....yeah for all the more I would use it I'd be better off paying someone....I've got a stick welder, and have an Oxy/acetylene setup I need tanks for..I see a Mig as a set up from a Stick welder but a step down from a TIG, but I agree there are times th eMig makes far better sense, and would be easier to use.

And a MIG is far, far simpler to master and get good welds on too.

FWIW, they all have their place in the world of welding.

SMAW is by far the easiest and most reliable way to join heavy steel. The only thing I'd trade for my ancient Miller spark box would be an engine-driven DC SMAW rig.

MIG is great for production, hobby work and quick stick-together fabbing but, it is doggone fussy about surface preparation. For grins and to make a point, I've laid down a great looking bead with MIG and popped it right off of the steel with a tap of a hammer.

I'd say that, unless you were regularly doing work for pay on aluminum or stainless, a TIG machine would be huge waste of resources and far too cumbersome to use for most shop welding.

Yep, occasionally we do burn some steel; that's 9" dia, 5/8" thick pipe — no MIGs allowed here!!

can't argue with this. I really want a TIG, but I'll make due with my MIG (Hobart Handler). I'm much happier with it now that I scrapped the original ground clamp and replaced it with a heavy-duty bronze/copper cast clamp with a tough spring. Still, I usually find myself using a higher heat setting than what the chart on the unit recommends so i can get the penetration.

i wouldnt put something that puts back pressure on the engine.. those mufflers are for gassers .. diesels like to breath.. easier for the air to escape the better.. so ive heard

SInce a cheap TIG is $1,000 plus , and a good one far more its a stretch I will ever get one...I will likely end up with a Mig with Gas shielding..not the flux core wire crap...and have the right stuff for occaisonally welding aluminum...

No I am not a pro welder....but I like having what I need to do what I need 90% of the time. Which I will admit is not that frequently. I am in awe what a good welder can do with a TIG.....its a thing of beauty...

makes sense. i just love the sound of flowmaster. my dad has them on his 64 mustang conv and 66 mustang hardtop and i just love the deep growl they have when you rev or drive fast.

Agreed! A long-time friend of mine is a TIG welder. I've seen him fix stuff that you never dreamed could be repaired, much less welded. On a beer bet, late one Friday afternoon, I saw him weld two 12oz Miller Lite cans together... shortly after he'd drank them (and the rest of the 6-pack).

Sometimes you have no choice but to use flux core. If you're in a location where the shielding gas will get blown away from the MIG gun's nozzle, cored wire is the only way to do the job.
