I´m looking for a new y-pipe since the one a bought from QTP dont "fit" the angle of the pipes are wrong. QTP says it´s an installation error (nice customer service

) Soo i wont buy a new one from them.

So what brand and where to get one. Thanks.

Why don't you throw that stupid, power robbing "Y" pipe away and install true duals that goes over the axle and out the rear? With the duals you will pick a good number of horses over that silly "Y" pipe system and you will also pick up a sound that is a real tribute to the LS-1 engine.

Don't you just love it when people hijack your post to tell you that you should go in a totally different direction from where you want to go? It so totally answers a question you didn't ask!

As far as your question, due to slight allignment/manufacturing differences between the different LT's, you might run into problems trying to put another Y from a different manufacturer in there. Your best bet to make sure that you don't run into further fitment problems (like you already have) is to take the car to a muffler shop and have them build a new Y for you. Also, that way, if you happen to have the QTP Catted-Y, they could most likely use the cats from that and then you don't have to buy new ones.

I second the muffler shop idea.

It ALWAYS will fit the best (it's custom) and it won't leak (it's welded).

Definitely the way I would've gone if I had to do it over.

Plus, driving the to the muffler shop with open headers is fun. Sounds like NASCAR!
