Datsun Deron Posted June 26, 2010 Share Posted June 26, 2010 Hi all, Well now that my car is finally back on the road and turbo charged I can start putting some of my documentation on here. I just wanted to say thank you to everyone on this forum for contributing and helping out. With out you guys there's no way I would have been able to undertake such a project. I'll try to make this as detailed as I can: Materials used: 10 feet of straight 3 inch aluminized exhaust pipe (dynomax) $50 2 - 180 degree aluminized exhaust bends (dynomax) $30 + $30 = $60 6 Muffler flanges and 3 gaskets - $40 Flex pipe (installed later) - $30 I also used 4 hangers and an exhaust reducer for my muffler but I had these laying around the garage Total cost for the project $180 Time spent 10-12 hours Materials left over - approximately 5 feet of straight pipe thanks to the extra length on the bends. Here is what I started with: Tools used (and a welder of course forgot to snap a picture of it): How I went about it: I removed my old exhaust and using the yellow angle tool I measured the approximate angles and lengths that I'd need. Based on that I knew what I had to order for pipe. I didn't actually have the down pipe installed (as it was being built) when I began this project so instead of working from the turbo back I actually started in the trickiest part first. I started working from where the exhaust goes over the cross member. I don't really know what the correct method is but it worked quite well for me. I assembled and tacked my pipes together as I went and once the cross member bends were done I worked my way back towards the muffler. Once I was able to line up with the muffler I tacked it and assembled the rest of the exhaust towards the front of the car and got it close to where I thought it would be. After I got the down pipe installed I was then able to complete the rest of the exhaust. I left most of the exhaust tacked and then welded it all up after I was happy with the fitment on everything. I built the exhaust pipe in three parts so everything is removable. It was VERY tight to get a 3 inch flange through the crossmember but with a little grinding its able to go out and in as needed. After everything was done and the gaskets were installed the fitment through the cross member was a little tight for my liking. In order to have some give I added a flex pipe which you will see on the "installed" pictures. Here is what I ended up with before the install, I have labeled the lengths and angles as well. (NOTE: These are all approximate and are by no means exact). (I "stitched" the side angle and top angle photo's together in photoshop if you are wondering why they look a little "odd" as well) Here is the exhaust installed: All in all it wasn't too bad of an install. I'm not too happy about having to reduce from 3 inch to 2.5 for my muffler but I'm just too cheap to get rid of my Magnaflow muffler and buy a new one. I might change that sometime down the road though. Hope that helps! Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 26, 2010 Share Posted June 26, 2010 Nice job! I'm planing to do the same here pretty quick. I have a full 4" system now, but Its too loud, plus it don't tuck under as far as I'd like, for me to be able to lower the car another couple inches.

slownrusty Posted June 26, 2010 Share Posted June 26, 2010 Nice job beautifully documented, I love how you put the angles on the layout. That is a sweet Magnaflow as well. Yasin Quote Link to comment Share on other sites More sharing options...

You can order aluminized mandrel bent kits off ebay for 171 shipped. It is what I am about to do, I am just glad I have some pictures of work so I can see what I may end up having.

Oddmanout84 Posted January 8, 2011 Share Posted January 8, 2011 Wow! That exhaust is great! Wonder if a similar setup would work on my S30 next time I get around to redoing it... Quote Link to comment Share on other sites More sharing options...
