Quote from: z284pwrI fail to see how it will affect emission testing?  Especially considering our '88 Beretta GT hasn't had one for 2 years now and the emissions readings are non-existant....literally. :shock:

Here they actually run the car on like a dyno. They simulate crusing and light acceleration to make sure the egr is operating.  Might pass without one but I doubt it. It's getting tougher to pass these test.

If you have good plugs/wires and a cat, you shouldn't have much to worry about.  We found that out.  Plugs/Wires on these cars can make the biggest difference.  We went from double limit on emissions readings to ZERO with just plugs and wires :shock: EGR can only flow so much to help out, I doubt enough to affect that, but hey, who knows?

Usually they do a visual inspection to see if it is there and if it operates. Not necessarily how well it works.

Running without one may not make you fail the test, but it will increase the amount Nox in the exhaust. As long as the level does not exceed the allowable amount they will most likely suspect that your car just needs a tune up. Or something.

Good/Bad you decide.

You could use a block off plate under the EGR -- depends on how strict the emmisions are in your state.

But you would still have to fix that EGR tube.

Or you just have the crossover welded, then put the hose over it, and put a plug in the EGR too, both sides pluged, its still "hooked" up, and they don't know the difference.

And like I said, both our '88 Beretta and the TGP were running without the EGR hookedup, and BOTH have NOx readings that are basically non-existant.  The Beretta has NOx of like 0 at idle and 3 at 2500 and the TGP like 3 and 5.  

A GOOD high-flo cat and plugs/wires are surely going to make a much bigger difference than a small EGR.

well, i got a replacemet hose from Jeff M and put it on this weekend.  I noticed that it actually idles a lot smoother now. Whether that has anything to do with NOx and what not I dont know but it did at least truly seal up my exhaust leak that was there so for that reason I'm glad I have it.  Here we have visual emision tsting and a gas cap test and thats all for emissions so I needed to have the hose "attached".

nice, I bet that thing is starting to run a lot better with all the love you are giving it.  I saw a stainless egr tube that came with my friends ceramic headers for his LS1 camaro...If we could get our hands on a few of those they could be easily modified for TGPs. Dont throw away the old ones because the threaded coupler could be attached to a flex bellow and would probably bolt right up to the bottom of the egr housing.

Im sure if anyone did try to make one they would be happy, and also be envied by everyone else on the board. they look sweet and made of mandrel bent stainless.
