Eta-to-M50: Build thread

[Jand3rson]

Josh,

Did you get the car back from the exhaust shop? I'm preparing to jump into an M50 swap very soon, and I'm anxious to see your outcome! I hope it turns out to be everything you want it to be!

I did get the exhaust done, and it's very well done, but it's very loud, way louder than I wanted. I didn't have time/cash to order the Vibrant I wanted, so I ended up picking up a Flowmaster for cheap, just so he'd have SOMETHING to put under it. It sounds good, it's just way too loud, and at about 3k, it has a really ricer-sounding rasp. I'll get something better under there late, but for now, it drives.

What I really can't figure out right now is why I have 7 qts. of oil in the thing, and it still barely shows up on the dipstick.

Just got done hacking all of that shit out from under my car. I never knew it was possible to feel so relieved and so pissed off at the same time.

Ok, so I know this has been gone over a million times in other threads, but I want recommendations on a good, inexpensive single in/dual out muffler. I'd like to stick with Magnaflow, has anyone had any experience with this model?

It's only $61, and combined with the Magnaflow I'll have in place of the cats, I don't think it will be too loud, but I find conflicting information on the noise level. Single 3" in/dual 2.5" out is pretty much exactly what I'm looking for. All of their mufflers look the same, but there's a dozens of them in the single 3" in/dual out configuration, varying in price from $60 to $150, and I don't know what the difference in them is.

The packing used in the muffler is the key. I am the aforementioned roommate Yoshi's talking about, and with just the Borla ProXS and the cat, you could hear me coming from an eighth of a mile away. Keep in mind I bought the longest 2.5" diameter metal matrix cat I could find (14" substrate, 18" total length) for this, and that helped a lot more than I expected in quieting the exhaust down. I added a 28" long Magnaflow muffler that weighs about 10lbs and that dropped it down to a block or so now. The more expensive ones have more packing; the cheap ones are empty chambers that will serve to only alter the frequency of the exhaust, not the amount of noise produced.

That dude's work is utterly terrible; I hope the next shop does better.

Josh, what was the brand/type of bedliner you used in the engine bay? I need to use some on my new motorcycle project.

DupliColor spray-in bedliner, any auto parts store with a decent paint selection will have it.

You ever finish your secret coil cover project?

Nope, I'm still kicking ideas for that around, but I have a general idea of what I want to do, just need to start working on it again. My main goal is getting this fucking car driveable, I'm really pissed that it's been total car-weather for the last month, and it just sits in my garage gathering dust.

Picked up my muffler today, and the car goes in Monday morning at 8am.

I think a flowmaster hush power will give you what you want. My dad just had a custom setup done for his e21. Magnaflow resonator and a magnaflow rear section. Its not super loud but does drone right at 3k rpm. So he's replacing the resonator with a hushpower muffler. They're baffled so they sound totally different than straight-throughs.

Instead of letting him fix it you should tell him to pay for the parts he ruined.

[Jand3rson]

LOL, actually had to talk to the guy to go back out there and get my jackstands today, and he said he wants to "fix it for me". I told him I'm going to re-evaluate how I want it done, and I will let him know.

Which will probably be about the 10th of Yeahfuckingrightuary, probably around quarter after never.

New 02 sensor from Levent got here today, just counting down the days until the 11th when it goes back to a real shop for the new system.

I have a dynomax super turbo too, it's pretty nice.

Have you looked at Dynomax Super Turbos? I remember a muffler shoot out a while back and it won. Flows pretty damn close to a straight pipe, plus they are inexpensive and quiet. If you have ever heard a bursch muflfer on up to '89 911 Porsche , thats the muff they use. It is basically impossible to get a quietish straight though system w/o enormous muffler volumes. I cut open my 89 325 rear muffler and welded 2.5 perf cores straight through and glass packed it. It is very mellow, maybe 15% louder than stock. I started off with 2 inch cores but it sounded like stock.
