who has a ture 4'' down pipe and is ss better the aluimmized

[rem1981]

I have 4" full turbo-back Magnaflow. And yes, stainless is better, but get what you can afford. There is no performance benefit. Stainless lasts longer.

What he said. Here's a stock down pipe and a 4" comparison for you. Both are 409 stainless. The 4" will end up the same color as stock from the heat.

where is the best place to buy is and can you get the muffler and cat delete

[rem1981]

There are a hundred places to get them. Try eBay. And I think mine came with the test pipe (cat delete) and the muffler delete, but I can't remember for sure.

Oh yea. Sounds better, more power, lower EGTs. It's worth doing.
