What's in the Box

Info

Using this kit makes the hook-up of your exhaust system a snap! The 2-1/2" diameter, 16-gauge, mandrel-bent tubes curve back at a 90° angle and are offset outward to clear the bellhousing and starter. They drop 10-1/2" from the header flange and they extend backward 17-1/2" after the 90 degree bend.

Just trim the length, weld on the 3/8" thick collector flange (included, with gaskets) and you're all set! Works great with any tight-fit headers. Header not included.

Nice product for the price. Curves of piping seems right and they are long enough to cut to fit for most applications.

too big a tube dia.

March 03, 2016
Wish they came in diferent tube diamiter size. If i could have got them in the same tube size as the header collector, i would have been done installing the exhust in no time at all. Car is so low to the ground that i need the extra clearence of a smaller tube diameter
No, I would not recommend this product.

I Used Pipe To Come From The 4 Tube Header To The Stock Muffler place. Every Thing Is All Wright But One Bend On each Tube Was Wrong So A Tube Bender Help To Fix It. It Put The Pipe Going The Right Way To The Stock Muffler Place. It All Came Together Just Fine.

No these wouldn't work for that, as they are 2.5" diameter pipes and most lake headers use a 2" or smaller pipe. An exhaust shop would be the place to go for custom pipes

When welding stainless material a comparable stainless filler material should be used. Our stainless tight tubes 91013386 are 304 stainless steel. If MIG welding a stainless wire, or if TIG welding stainless filler rod will be needed.

Yes, you should have little trouble bolting these EXT.PIPE FITS TIGHTFIT/PLN, part number: 91013385, onto the stock style Corvette manifolds. Worst case, you would have to elongate a hole or two in the flange for a perfect fit.
