Default Anyone using this Catco Ypipe-Cat combo

Does anyone have any experience with this L98 replacement component? It looks like a decent price for a new ypipe,and main cat combo.

link

Is it louder, better flowing?

thanks

I you sure they include that y pipe. I see it shown in the picture but nothing is said about it in the product description.

montie,
It appears to come with the Y pipe. It is comes up under their ypipe link. The cat looks like the one that you get for $139 on its own, so the Y pipe component is a bargain (assuming it is not waffle bent).

Also Converter Overall Length (in): 64.500 in.

Default i bought that

I installed that setup on my 88 after the right side precat started rattling around and cloging the pipe
you will notice its slightly louder
i replaced the oxy sensor at the same time and i feel its a good pipe and cat so far, its been on my car for about 1k miles or less
the y pipe is not mandrel bent and seems to have the same bends as stock
you can sell your used cat to a scrap yard for at least 50.00 and they will take your old y pipe as well. its like a rebate
not much to the install but i had to cut the air pipe to the cat to size.

Thanks for the info. It sounds like a pretty good deal for $175 after the "rebate".

Hello There,

R U saying its waffle bent and not mandrel as it appears to show in the add at Summit which is now up to $216? Do you still have it on the car? If so how has it performed?

Thx!
