What are the current thoughts on exhaust? I have no smog res

My new 02 is pretty much all stock from cali, so its got all the smog equipment. My plan is to sell off most of the restrictive smog parts and replace for a cheap simple set up. I'd like to go with another lynx sidedraft set up with a 45DCOE on the front side, but I'm not sure what exhaust would match up best. The Tii exhaust manifold is supposed to be pretty nice right? But will it be as good as a cheap set of headers? I dont want to drop $500 into some SS set up though... just looking for something cheap thats not going to be too restrictive.

Also I DONT want any rice sounds. But what exactly causes the rice sound? I always thought it was glass packs and strait pipes that caused it, but I see here and a lot of other places people running glass packs and pipes and claim to have a very different sound. I'm looking for something fairly quite, but like I said I dont want anything that will hold me back. I plan on running it fairly stock for a while aside from the new intake parts.

performance,backpressure,and sound that i have had "civilains" ( non 2002 geeks) come up to me and ask "who works on my engine?" because they like the sound of the exhaust at idle,or low rpm in parking lots. I had to add an extra pac for the noise gun at Laguna Seca: 95 db @ 50 feet during non race events. One pac was fun, but rather "aggressive" and it shook apart the system periodically. However, it never sounded "tinny" like the fake crap on imports that add nothing to performance. The tii ex. manifold will work well for your system,as described. It is roughly equal to street Stahls.Most people will tell you to stick with a stock tii exhaust system- 2002s were called the "whispering bombs" at the time, because of their relatively quiet exhaust for the performance. If you want pics of the custom exhaust under my Sahara - let me know. I have a few posts on the Boards now that show parts of the system, in answers to other questions. Good luck.

If you are looking at a new Stahl or similar header vs. a tii manifold, the latter will be about 85% of the performance, significantly cheaper, and less noise. But, you can get used headers on ebay and other places that even out the price difference. The noise difference is not significant in my opinion. ANother header consideration is that they may crack, whereas tii manifolds don't.

BTW, unless you're doing the innerds of the motor, 40 DCOEs are more than sufficient. And even if you go with 9.5 pistons and a 292 cam, 40s will be fine for the street. With this type of motor, either the header or tii manifold will work, the latter squeezing out a few more ponies.

I'd like to see some pictures of your exhaust. I'm getting ready to fabricate an exhaust, so pictures would be quite helpful.

Thanks,

Rob.

Dude..manifolds crack. They're just shitty casts. Maybe when they crack they dont sound as bad as when headers do, but they definately do crack. This is a Tii manifold that I got as one of the many parts in my (freebie) white car:

All 3 of these are all the way through. There are more but I cannot tell if they're through or not.

so here goes:(i have taken digital pics of just about every inch of both cars'undersides for reference and proof of condition: please excuse the blow-back in the Sahara shots- most of the shots were pre-new engine and done without a "shoot clean-up". The sequence is just from the engine( headers) back ....here are the Stahl headers on the engine( new engine)...standard.jpg....header collection point....standard.jpg....headers to flange/coupled to mesh pipe section beginning.....standard.jpg......another view of that connection....standard.jpg....and back to pipe...standard.jpg....to glas pac....standard.jpg......standard.jpg.....to pipe and another pac....standard.jpg.....aft pac...standard.jpg....and out to tip...standard.jpg....here are 2 other views of the under/over angles at rear end....standard.jpg.....standard.jpg...hope this helps. The only unique thing I came up with was the 12 inch mesh section: normal 2002 engine twist was causing cracks at welds and was wreaking havoc with mounts. So, the mesh eliminates a lot of the motion transfer to parts aft of the section. I have had to "create" some different mounts due to soft metal. you can see that in the pics. This system has stayed solid and together for over 2 years now- which is good compared to my previous 1 pac system that was in for a repair every few months. Yhe mesh section cost me around 200 bucks alone. The rest is pretty cheap: pacs wear out but are easy to cut out and replace.

    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
