Need a 4.5" I.D. Stainless 90 where?

I need two stainless steel, 4.5" I.D., 90's or one, 4.5", I.D., 180 bend to make turn outs for my side pipes. It's an odd size and I have had no luck finding them.

Any thoughts?

Thanks,
1930U

Thanks for the info. Here's some pics of what I'm into...big block chevy headers adapted to fit a 392 Hemi. The collectors are 4.55" OD. I made the side pipe tubes from stainless sheet stock. They came out perfect and if I can just find or fabricate a turn out I'm good to go. The wall thickness is also an issue. I need like .050"-.060.

Thanks again for the info.

Burns stainless has 4.5"OD 90's part # LB-450-45-16-304

Your Price: $118.58

Quantity:

LB-450-45-16-304
L-Bend, 4.5" OD, 4.5" CLR, 16g., 304 SS

Find Custom Exhaust, Header Collectors, Race Mufflers & More | Burns Stainless

I found them in the 304SS section. They are 4.5" OD , but to me that means you could slide it into your side pipes and weld or clamp in place. Probably look OK...........

The Grainger and McMaster pieces are heavy wall like schedule 40 much to heavy but the Burns 90 wall thickness may work.

Thank you all !!!!

The Grainger and McMaster are in fact .120 wall, which is sch. 10s. Sch. 40 is .237 wall. Refer to a pipe wall thickness chart :-)

Thank You 1930u!
