New exhaust studs too short?


CubbyChowder

Recommended Posts

I recently ordered a new set of exhaust studs/nuts and noticed that they are a bit different in design. The original ones had a shoulder (unthreaded section), and my new ones are all thread. The new ones are also about a quarter inch shorter in length than the originals, my dad is convinced they wont work and is very hesitant about using them anyways. Did I receive the wrong studs or do people use these all the time? I ordered them through Blunt using part #'s that I found on numerous articles/write-ups here on the forum.

That is what I ended up with too, I just made sure that there was enough exposed stud so that the nut would lock properly. This was about 2 months ago and so far they have worked fine but as you probably know the real test is over the long term. I got mine from Blunt.

and use the correct copper exhaust nuts with washers, please

CD--why washers on the exhaust side? I have never used them over the past 20 years and have never had a problem with either the nuts coming loose or not being able to take them off when I need to. RealOEM does not show washers, only the copper locknut: 11621744323

Same goes for the downpipe. RealOEM only shows a nut (18301737774) and I have never used a washer here either. What is the critical factor you are concerned with?

Thanks, Fred

Is there a correct part number I should be looking out for? Kind of sucks I need different ones, I doubt I'll be able to return mine since we threaded them in and out a few times while examining them. Oh well, what's another $20 at this point.

I sent you OE BMW studs by part number ... if youre unhappy in the least all you have to do is call and Ill take them back. But thats what youre going to get over the counter at BMW I would never sub aftermarket parts for OE stuff unless requested. Im glad to take them back whether youve screwed them in or not. but those are the correct studs direct from BMW

Interesting, I wonder why they changed them. I was in no way trying to talk down your business at all with this thread, I've been more than happy every time I've ordered through you and I'm a returning customer for a reason.

I guess there's no point in returning them if that's what I'll get anywhere. I appreciate the offer to return them though.

They changed them because they are cheaper to produce without the shoulder. Its the way of the world I guess. I know you wernt talking us down I just wanted you to know those are indeed OE

You can get the correct sized ones at ACE, I'm running them on my 02 right now. They have a shoulder too.

Washers?

Interesting this came up. I just removed my 10 month old downpipe in advance of removing my transmission.

I can see discoloration on one edge of the (10 month old) gasket that tells me there is an exhaust leak. I've never seen washers used there, but it may help this potentially aggravating problem.

A leak there can potentially cause backfiring (?) as air is sucked in on deceleration. Am I right?

The washers are built into the sigle use, copper exhaust nuts.

my dad ended up going to a local NAPA auto parts and they had basically the exact stud as the originals, only the shoulder is a tiny bit longer, shouldn't affect anything.

If anyone is interested in my ones that I ordered from Blunt, you can have them for cheap. Just email me at mikey.gaumann@yahoo.com

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
