bends for a 3" exh on 1g awd?

[EuroGSTSpyder]

I was wondering mostly what the bend for the DP is regarding degrees? Its not a 90dgr bend right? More like 70-75 or something? Also would like to know how long (roughly of course) the straight pipes of that bend have to be?Does anyone have that info ?
I am buying pipes to make my own 3" and I am mostly concerned about the DP since I havent removed my old system yet.
The hump over the rear axle is not a problem cause those are easy to buy premade ..its mostly DP bend I want to know what degree it is:-.)
What are the other bends i will need to get this going....?

Besides that it seems like a pretty easy system to make actually...or am I missing something? Dad has been a welder for 15 years so I guess I can say he is qualified to weld the system up for me ;-)


I will make a straight through system with testpipe so I can replace it with the cat to pass eyarly inspections here ....Still dont know what rear muffler to use though...not sure I want a 4" tip..I might go with two big ones like I had on my spyder instead...well time will tell

I believe it's 72 degrees. Something like that. one of the local vendors (I'm thinking RRE) sells the right bend. I just used a 90 and angled the cut for the flange.

The rear bends are easy. 2 90 degree bends should be plenty for everything after the downpipe.

Here you go. It's only 2.5" though. I'd use a 90 degree 3" bend. Just be sure to pinch it in at the flange so you can get the nuts on.

I thought the 90* didnt make correct fitment after the DP. I have mine pie cut with all 45* bends. Its like a 80ish bend.

from rre:

72 degree bend is the perfect bend for making your own DP.

And I assume this goes for a 3" as well as the 2,5"...

72 is about what mine is, I attached some pics so you can see. Road race also has link on how to build a 1g awd exhausthttp://www.roadraceengineering.com/eclipsetech/1gawddiyexhaustpics.htm
