So I found a Magnaflow catback exhaust pn#15778 priced relatively cheap. The problem is I have a 2001 silverado ECSB and on the listing and everywhere else the catback is listed specifically for 2003-2007 silverado ECSB. Would the catback fit my truck perfect, will it need modification, or is it just not going to work.

Thanks in advance.

 

Should be exactly the same you would think

 

i think that where it bolts to the y pipe is different. How much did you find it for if you dont mind me asking. i was looking into the same catback but other things came up more important and i just ordered a muffler. The cheapest i found was $445 shipped.

 

i would be getting it from a friend of a friend. He wants $300 for it. I believe it has 20k miles on it.

 

I would get it and if all else fails you could sell it or take it to a muffler shop or if you or a friend can weld then weld your factory flnge in place of the one on the magnaflow if it is in fact different.

 

Your 2001 ECSB has a crossmember that the 15778 will not go around.

The factory exhaust had a bend in it that goes over the top to get around the crossmember. Some cat-backs go over it, and others go under it. Mine goes under it. I'll see if I can find a pic.

 

The kit you asked about will run straight into this crossmember. I've already tried.

 

I need this kit minus the muffler, I have a corsa I want to install. Anybody know where I need to look or have a part number? I'm not having much luck
