Pics of my Grotyohann Y Finnally got some pics. I designed the Y and a couple buddies Mike, and Ryan, help build it. I used slip fit mandrel turns, 3 to 3.5" Flowmaster collector and a Dynatech Split flow muffler. The tone is deep. I really like the sound. For the first time around. I couldn't asked for a better outcome. I think I will try a X next.
Before this set up. My exhaust was totally stock. My best was 12.97
With Grotyohanns and this Y.
My best is 12.55

How is the resonance with that system?
Nice and light too <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Pics of my Grotyohann Y I bought the two 3" ball flanges from Thunder Racing. I bought all the mandrel bends from Air Flow Systems.
http://shop.airflowonline.com/Merchant2/merchant.mv
Two 3" Ball flange starters. Two 3", 90' bends with 3" radius for the passenger side. One 3", 80' bend with 6" radius. One 3", 90' bend with 6" radius. Two 3" extensions. A flowmaster collector with dual 3" in, single 3.5 out. A 3.5" extension and a single dynatech split flow muffler.
http://www.secureperformanceorder.co.../splitflow.cfm
All of the piping was slip fit. The Driver side was flattened a little so the pipe wouldn't hit the floor under hard shifts. We flattened the pipe with a vice. Make sure the 80 degree turn comes off the flowmaster collector <Driver side>
It sounds super nice with a really deep rumble. There is almost no rasp. The split flow mufflers sound bad ***! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Re: Pics of my Grotyohann Y Is all of the piping aluminized and then coated in black or are the longer pipes stainless? You did a great job and I will be using your y pipe as a reference, when working on mine.

Re: Pics of my Grotyohann Y did you need any brackets to support the muffler? i was looking to do the same setup but only with a Hooker aerochamber muffler.

Re: Pics of my Grotyohann Y <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> For a hanger. the back seats were taken out. We pulled up the carpet, <You don't have to take it out, just lift up. Then we drilled a hole in the back rest of the rear seat, to bolt on a hanger. I clamped the hanger onto the turn down. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />
