I use a snap-on 1" hole tool and some soapy water when cutting into SS to keep the weld area clean and cool the bit. Best bet is to get the hole just right to fit snug, if its too loose, tack on one corner and bring it up, and fill in the "slight" gap you may have.

Sounds good. My system is only mild steel, so it's a bit easier to work than an SS one.

Finally finished the front half of my system. See the first page of this thread for the cat-back parts.

2" piping with an offset cat from Magnaflow:


I heart welding


Two of those under the car:


Flanges I cut on the CNC mill at school welded to a Magnaflow 2-1 main cat. Yes, I have 3 converters.


Left side pipe tacked in place:


Right side pipe being finish welded:


All done the front pipes:

O man, Mazda MP3, I had to make one for a customer, damm water neck was so damm close, I made an extension on the water neck to move the hose 3" forward and 2" towards the passenger side with a slight downward kick just to clear the 3" d/p, and yes mad pie cuts.
One of my tougher jobs on a big turbo B16 in the shop.

This seems like the right place to ask this... I am looking to reduce the overall volume of my exhaust system, without using cats. I plan on using a 3" borla hush catback to accomplish this, but I'm looking for an even quieter ride. What would be the best product to use to reduce decibles? Muffler, or a resonator? What are the differences? It would need to be a 3" design and I am looking to maintain flow while decreasing noise.

Sort of. I built a 4" dp that connects to a 4" cut out. The cut out is obviously side exit 4". This is on my 08 WRX.

I've done a side exit, but not on a Subie. I used a Vibrant race muffler in place of cat, and a Vibrant Ultra Quiet oval resonator on my Sentra, was quieter than my VRS exhaust w/ Magnaflow muffler.

Same two sets here. The set they used is on the left



here is the logo cast onto the flanges

Who makes this header? I just picked up the unequal length version, but haven't found any information on it.
Thanks,

Awesome, awesome work you guys. I am to the exhaust stage in my EG33 Legacy Rally Car project. I'm a total exhaust noob. I need to whip up a tighter fitting exhaust than the stock Y pipe but am unsure of the material to use. I am going to reuse the stock cast headers to retain that durability. So what is a good material to use? I want to keep it cheapish so I can build 2 and have a spare.

Check out the system I did for my SVX (post #5 and 78 in this thread). I just went with off the shelf mild steel tubing. If you don't want to run cats then the whole thing would be quite inexpensive.

Here's mine, TBE on my 04' FXT. The exhaust line(but DP and piping is) isn't all tig weld but the goal of the project was to learn how to tig:

I'm interested in both of these. Recently moving, and the place I'm moving into I need a quieter exhaust. Did run the resonator before or after the race muffler?

Also, I'm really interested in making a side exit exhaust for the wagon too.
