    Well, first let me just say that sattellite internet SUCKS!.....Okay, I feel better now.

    I swear evertime I get close to doing this something come up! Last night on my way home from work the yellow check engine light flashed at me a few times. It was the coldest it's been here lately....and I thought maybe I just didn't warm it up enough. But then it did when I was almost home too. Seemed to do it upon medium/normal acceleration.

    So, now I need an OBD-I code reader because this is going to bug me. No drivabilty issue's. Nothing appears visibly wrong. If not for that light, I'd not know the computer was having a fit about something.

    ....mostly I just want to make sure it's nothing emissions related (or expensive) before I have exhaust work done (since it will all be welded).

    I drove it today with no light though........

      I felt an immediate gain in low-end torque after a crossover was properly put in. The exhaust shop painted the mid-pipes, took the car out for a run, and placed the crossover right where the pipes seemed hottest. On my car, these spots were not directly across from one another. These cars need all the torque they can get. As an added bonus, the crossover ("H pipe") adds some stability and structural integrity to the exhaust. Less broken welds, stress fractures, and loosening flange or header bolts with an H or X pipe. As far as sound is concerned, adding an crossover mellowed the sound out a tad, and sounded a little deeper, too.

      Oh, and Flowmasters actually sound alright on these cars. Must be due to the long pipe lengths and amount of turns needed.

        Fixed that.

            An OBD-I reader can't read EEC-IV codes anyway, can it?

                Yeah, I thought there was a way around having to get a code reader, but I wanted one. There are starting to be a lot of OBD-I cars in the family, figured it would be handy.
                Came with a book that had all the codes listed in the stickies here and a whole lot more that aren't.
                (and it was cheap)

                But, back to the topic at hand.......

                Anybody got a really good H-pipe pic they can post up?

                I've never asked my exhaust place to do an H-pipe before and I don't know if they do the "crayon" (or paint) trick to see were the "hot-spot" is, but they bend pipes up really well. If I bring in a pic and say "make it up just like this", they will.

                  Well jeez, (custom) performance exhaust around my neck of the woods seems pretty dead.
                  Nobody (well except that guy that wants a grand) does any kind of heat testing to see where best to put the "H".

                  So I'm kind of back to square one.

                  -I can either tell the place wanting $400 where to place the "H" crossover, and hope for the best,

                  -Or say fuck that and order the walker system.

                  Choice one is nice cause I'll have bigger pipe and better mufflers that are warrantied forever.

                  Choice two is nice because I'll have the satisfaction of knowing I did it myself. The pipe will be only 2" but I'll be able to unhook things if need be.....and save some $$$ too. I just don't know if I'd be happy with the muffler choices/sound and/or performance.

                  Still unsure as to whether a stock lopo would get all that much from the larger diameter pipe.
                  (I would like to think it would though)

                    If you don't know for sure the best place to put it, my exhaust guy says his customers (and himself) have the best luck with as close tot he engine as possible, makes sense since that's where it's hottest and moving fastest at.

                        Yes, but what is the point to that if the rest of the system is smaller?
                        ......Or are you saying it would make it louder?

                        Long story short I'm back on the fence again.

                        I was looking around to see if I could find any nice mufflers that sounded good AND FIT with the walker system. Doesn't look like magnaflow makes any 2" in/out that are long enough.....but if they don't fit directly I guess that's a good thing as it leaves room for adaptors.

                        I just put in for (and got) a week off early next month. If I want to go to that shop I need to make my appointment SOON. If I decide to do it myself then I need to start ordering parts.

                        I (really) appreciate the patience all you mangs have had with me.

                        Does the lopo (stock) flow/breath enough to actually make use of 2.25" pipe?
                        Or is the (dual) 2" enough?

                          If you buy stock stuff pipes are around..15 dollars for one...and maybe 25 for the muffler...h-pipe is a little more pricey new...but you could yank a used one and do a stock duals setup for under 75 bux if you do everything right. That alone will gain you 10-15 extra HP and of course better fuel milage.

                          I was just saying that the 75 dollar pipes are cheaper than $400 custom ones..

                          I used adapters on my setup to make it work (stock h-pipe to 2.5" mufflers/tailipes.)

                              Simple way to do this is... Go get the 2.25' system done, let them know you will be back in an hour or so, go paint the pipes and drive back. Get it in the air, and show them where you want the H installed.

                                As I recall, you got headers, but no H or X pipe right?
