My dad has the steel Ebay pipe on his 03', it is working very well for him.

So, the Steel one is best one to get so we don't get the flutter?

 

Steel or stainless won't affect flutter. You will more than likely get a little flutter with the ebay Y-pipe. My dad has the steel one because that was the only one available at that time, the stainless y is a somewhat recent addition.

 

Surely there is someone out there NOT affilliated with the Ebay sites that has done a real honest to goodness before and after DYNO Testing of the Y-Pipe Mod???????

Not that I don't believe Ebay sites or those who have invested the Money and Time.....

My 2000 F-250SD is just about ready for some serious exhaust system work....thanks to all the Mag Chloride on the Idaho roads. Almost convinced to go with the Y-Pipe but can not afford any possible drop in Low End Torque.

 

You won't lose low end power. In my experience you actually gain low end. The necked down stock Y-pipe is only to eliminate flutter, thats it. Performance only improves by removing the restriction point.

 

Here is the Y pipe I got from summitracing.com. Check my gallery for full install. Works great at all speeds!!

 

Any flutter associated with the Summit piece?

 

Wish I'da seen this Y-pipe before I bought the e-bay one!!

 

Isn't that made from PIECES from Summit, not a complete pipe available that way to begin with?

 

Thats just a flowmaster universal Y with some bent up tubing connected to it. He has detailed install pics in his gallery.

Oh! I see the tack welds now! Thanks! I'll stay with my e-bay Y. LOL

 

NO FLUTTER!!

 

C'mon...I got a video posted of mine with the Summit pipe. You can clearly hear flutter.

Maybe your SC does something to eliminate or reduce it??

 

That could be. Or, the muffler man that installed it knows hot rod stuff. I also have Magnaflow cat and muffler.

 

I just had the ebay y-pipe installed. I had the 99-2000 McD styled pipe. This is a new truck for me, my other 00 V-10 is a 2 wheel drive. I had a custom pipe built for that one 2 yrs ago. The Ebay pipe fit good, cost me $100.00 to have it installed, I have a filter minder gauge on the air inlet tube behind the MAF.. The increased flow & vacum was very apparent, up to 15 from 9 (in H2O )at WOT. the tires smoke off the line easier as well. So I know that mod is allowing the engine to breath easier. one note, it reads the same with my K&N or the paper filter. So now, I will be easy on the throttle & see if I get better Mileage. We are paying $1.33 per liter up here in Vancouver .OUCH !
