Auger style muffler inserts???

do they mak'em in 2.5....saw them on one site for like 100 and sum dollars...im talkin the like 14.00 dollar ones like speedway has...just need them in 2.5

 

I just made mine out of LARGE washers, cut-split-bent, welded them to a steel tube, made a tab, slid them in.... they sounded great.

 

Yes. www.spiralturbobaffles.com I believe.

 

awesome...thanks

 

Do they work? Any U-tube vids?

 

I made a set very similar, just with blind washers cut in half.

 

I use them on my circle track car. 3.5 in and out. 406 small block and under 96dba at 100 feet. I can not feel any power loss.
