Help with exhaust please

ive resently been redoing my whole exhaust (except headers because i didnt even want to mess with them because of the problems ive already had.) and my dad and i managed to break off some of the bolts that hold the Y-pipe (i think thats what its called)to the headers and when i say broke i mean the things are practiclly welded into it because it hasent been touched in about 13 years. know does any one know where i can get a stock y-pipe with the flex. or something that will bolt straight up to the stock headers.

Thanks a lot for any help

(would i be able to order this pipe from mazda?)

i found this pic on ebay for $130 would that bolt straight up to the stock location? because if so ill just get those!! even tho it comes with everything else. and depending on how hard the headers would be i could have the muffler shop i got to go over the welds to strengthen the welds and install these headers myself (hoping none of the stock header bolts would break

i say go with the headers. I'm sure Mazda will get some for you but it would probably cost as much as the ebay headers.

how much do you think it would cost to have an exhaust shop to go over the welds to strengthen them?

welding them up will cost more than the headers themselves, they are a rather cheap replacement that will serve you well enough. That Y pipe will not bolt up to your stock manifolds, it's to short and of a different design on the header end if I recall.

If you can get the car up on some ramps it will make things a little easier, but the rear header is a pain in the rear any way you do it. The EGR tube is trash, I couldn't get the one they sent to work on my car, it's plated junk just make what you have work, make your own, or block off the EGR.

It's that J looking tube in the lower right hand part of the image you posted. Thats the part that sucks.

Search the 2g projects section or threads I've created (from awhile ago) and you'll find a write up on how to install those headers. Complete with pics, explanations of the EGR tube, what you'll need, etc. It's not really a difficult install but will probably be time consuming for a beginner. I too agree with just buying those headers off ebay. It'll cost the same or less than any replacement y-pipe.

So how important is the EGR to the performance of the engine? I thought it was a key component for keeping things running smoothly (as well as emissions)...

Just wondered 'cuz I've been reading up a little on turbo systems, and it's pretty rare that I hear of or see a turbo car with EGR since most (if not all) of the exhaust is routed to the turbo... I was wondering what would happen with that if you turbo a car that *does* have EGR... Wrong forum I know, but it's the right subject anyway... lol

never mind i just found it and read it. VERY nice write up. i was leaning twords a shop installing them to save me the hassle of doing it.but i think i might give this a shot. the reason i have to do the headers is because of seized bolts and nuts that actully completyly broke upp after soaking in pb blaster 3 times for 30 mintes each.......wow. how long did this take you about. and the only other thing i noticed is yours is ssautochrome the ones im looking at on ebay doesnt say anything about ssautochrome( you said "Here's a picutre of the stock y-pipe off compared to the new SSautochrome headers.")

thanks a lot you may have saved me good money if i can do this myself

There are many options that you can look at check out this post, http://www.mx6.com/forums/2g-mx6-oth...ders-look.html (Different headers? LOOK!)

We tend to call headers from ebay all SSAC headers because they all are very much alike and are more than likely produced by the same company.

Doing the work yourself is a huge cost saver, and you'll be proud of the work you did. I'm sure when you step away from the car after you finish the install you'll see the car in a very different way. It becomes a product of your hard work, thats something an exhaust shop can never sell you.

Just so you know, the EGR tube won't fit. It's too short, or maybe I'm just really unlucky.
