ARSPORT Exhaust Adaptor Male & Female 1" Flange for: Predator 420cc & 301cc, Hond GX 240, 270, 390

Very nice quality but this is definitely not NTP sizes. I have a 1" NTP pipe from Menards and does not fit at all. Will only make it two threads deep and gets stuck...

I used this to make a custom exhaust for my lawnmower. Will fit a Briggs and Stratton 13.5-17.5hp engine with some slight filing to make the bolt holes line up but worth it. Also it is the same thread as a 1in threaded galvanized pipe. 👍🏻

Easy to install

My 2013 Craftsman LT1500 muffler broke off years ago due to the OHV valves getting loose and causing a big backfire. I had struggled for years trying to AC weld, jb weld(haha) and later, DC weld an muffler back on. One day I had the idea to look into if someone made a part for it. This is the part, however read on, no one made a part that was for the screw hole 2 and 1/4” center to center, this is 2” center to center, so I spoke to the manufacture and he informed me that I could slightly modify the part to add an 1/8” on each screw hole with a dremel and it worked perfectly! So now I have a perfect part and working mower! Thank you so much!

Used on my mower it fit good

no problems

The media could not be loaded.  My Honda Can-type muffler was rusted out on my logsplitter, but even if I replaced it, it would still be loud with exhaust fumes in my face while using the logsplitter. I stumbled on this little gem here on amazon and I was doubtful about ordering it. The description did not say that it would fit the GX240, but I emailed the seller, and he said that it would with a quick reply (240 and 270 are similar). It sure did work, and he/she knows their engines. I could not be happier with this adaptor, and I coupled it with 1" galvanized pipe and a 1968 Motorcycle exhaust, and now my logsplitter won't deafen me while using it, and it sends the exhaust out the back. It sounds great too, the video doesn't do it justice.

Could wait to right a review after opening the package. This is an amazingly high quality part. Fit my generator perfect. The weld around it is perfectly done. Like a robot welding machine did it. I’m so glad I got this part form this seller. Gave me 2 options on hooking up my exhaust extension for me 8700 watt sign wave predator generator, it’s sitting in a inclosed dog house outside my house. I’ll make a video of the hook up soon and post it. Thanks for the excellent part! USA all the way!
