I was just wondering if anyone has a magnaflow cat (wye, 2 in, 1 out) on their truck. and if they could fill me in on how much difference there is compared to a stock cat, like sound and HP..if any

 

Sound mostly, but you may notice a slight acceleration/power increase (I did).

Depending on your year (you may want to make a signature with all that info in it) of truck, you may have the 2-to-1 unit like you attached, or you may have a 3" 1-to-1 unit. 1999s to 2001s mostly had the 1-to-1, but some 1998s did as well I believe.

 

your truck will get loud as a mother ......... lol depends on what muffler you have on too, my truck is a 2000, i had to get si/so cat , so letr us know the year of your truck so we can help

 

My '99 sounded WAYYY better than it did before and had WAYYYY more power!

 

That's because the factory cat was probably bad. And what muffler you got on it?

 

I ordered the exact cat you have pictured, besides having a difficult time finding someone to install, it is an awesome addition!


Get it.

 

The factory cat was bad. It was throwing a CEL and was choking the engine.

I got a Dynomax Super Turbo muffler.

 

I did the same. Much louder, but I also changed the muffler at the same time.

look here for my thread on the subject

well my truck is a 98 and the stock cat is a 2 to 1 unit so i want to get the magnaflow cat in the picture. its 2.5" then the muffler i have on the truck is a 3" magnaflow. i pretty much need to replace the cat since mine is cracked and it makes a "hissing" noise. it sounds stupid. so i'll get that magnaflow cat welded on so it's sealed and loud, cause thats what i want lol

 

You will love it.
