It's a 3 speed auto FWD Sound big mean and fast, when really it's not.

I'm thinking about some plates "2SLOW4U":brow:

sounds like my '78 Brat did when I had my custom exhaust but it wasn't dual. Go gen 1's with custom exhaust. They rock!!!

[Kostamojen]

Wow that sounds great! Wish I could save the vid though...

I'm going for a custom exhaust whenever mine is smoged and running right (probalby a long while), glad to know it sounds as awesome as I thought it would sound

Son of a Vondruke! I got 1365KB into the file (long time for a 3.5K modem) then IE just quit. Is there audio I can d/l?

It only cost $200 at the custom exhaust place:)
I'll get some pics up later.

[75subie]

so did you scrap the y-pipe and make it a true dual exhaust?

[Mr Fishums]

reminds me of my old dual exhaust! sweet! mine was higher pitched though, on an EA-81. Nice paint they yellow is kinda wild but it works!

[REXSPEEDWORTHY]

he cut the y pipe before it joined together, so yes true dual.

[Zefy]

oh man i can't wait to finish mine now!!!

i got 2 1/4" pipe going into a performance resonator then stock the rest of the way back...

150 more bucks and he'll top it off with a magnaflow or something...

[Mr Fishums]

I might start making custom mandrel bent Y pipe header manifolds, I will get some pictures up of the one I am working on when it is done. As for changing sizes in pipe, you don't want to go from bigger pipe to smaller pipe.. you can burn up your valves that way. Duals are great, but your engine will run smoother with a Y pipe. It creates a suction that helps pull exhaust of off the oppoising cyclendar, great for low end torque! Duals would be great for a really free flow application with an aggressive cam and over size/dual carbs...
Matching you intake pressure with your exhaust pressure is the best way to go.

as for size of pipe only go:

stock size to same size

stock size to bigger size

big header to bigger pipe

If you don't think this is the case weld a plate on the end of your muffler then drill a small hole through it, you'll get the same results quicker

here are some pic of mine.

i will be doing something simular when it warms up outside. i just went today and picked up a 2.5 inch thrush glass pack, and some piping and clamps since i don`t know how to weld:mad: it should sound pretty sweet, going to do a single so i don`t sacrafice back pressure. and then a big chrome tip to top it off:grin:

do you guys thing the glass pack should go up towards the y-pipe or towards the back?

[Caboobaroo]

more toward the back since it will give you a more throaty piped out sound because it would acted more as a muffler when its installed up front. My '78 sounded AWESOME! So awesome that some crackhead stole my muffler in the middle of the night in front of my apartment complex...

[SakoTGrimes]

Be careful, I did the same thing a few years ago, using very tightly clamped clamps and JB weld to get the muffler on the pipe, but it still fell off (on the freeway). It would be worth it getting another board member to weld it for you; Adam NDJ did mine for next to nothing.

[75subie]

yea, maybe that is the way to go, the glass pack actually has quite a bit of weight to it, so that will also put some strain on the piping. i am going to try and make some rubber hangers too.

yes, welding is your friend when it comes to exhaust. I welded mine all up on my '78 and had no leaks! Also, get a stock EA82 muffler and cut the metal hangers off of it and weld them onto key locations on your exhaust so it can hang from the stock location. Just make sure you hang it before you go welding it all up.

[cowboystrait]

damn sounds good rex sound jus like my brat when it was runin it had duals on it too:headbang:

[Mr Fishums]

hey jon I'll weld it up for you, if you drop off the seats and skid plate It's required you go 4 wheeling too lol! I can't seem to find the time to get away from work lately! Overtimes a pain !

[75subie]

sounds interesting:brow: only problem is that i got my liscence suspended again:banghead: ......its a long story:-\ and it wasn`t in a soob;) it was in that damn fast hyundai:lol: maybe still if i can get a friend, or my pop to give me a ride up, and tow the brat behind. that would be cool to weld up the exhaust and off road for a couple hours (one place where i can still drive:D )

any progress on the hatch? hows she running?
