okay there is this down pipe that is on partstrain.com sry i dont know how to link and this was half-way discussed in a previous post which i cannot find (again sorry). but anyway its a cat with a u-bend delete from magnaflow my question is will i get any power gains from this? as you may know i just got my exhaust done and id really like to add this to it. any input would be appreciated>thanks. also it is under teh category of performance so i have to belive it would give me some kink of hp>

 

From what I have heard about the other aftermarket downpipes for the 3.4 they are garbage and a total waste of money.

If you want to get rid of the U-bend just go to any exhaust shop and have them cut it out and weld in a straight pipe with a bung for the oxygen sensor.

Paying all that money for a downpipe that doesn't remove any restrictions but the u-bend is a waste of money.

Unless you can find a used ZZP downpipe for the 3.4, they stopped making them.

 

I think Mike gave some really good advice. How much is it? Plus, although they're supposed to just bolt right up, they don't always. You may end up like an inch out of alignment or less and it just not quite want to bolt up... and your bolts could be so rusty they don't want to come loose, and it could be a lot of pain for little gain. If you're that concerned about your cute, adorable little u-bend, go get an exhaust shop to weld in a piece like Mike said. Good luck finding an exhaust shop that is willing to touch it.. lot of them like to say "Well it ain't that restrictive" and "your Check Engine light will come", apparently they don't understand that I want to put the O2 bung over on the side a little bit and still run an oxygen sensor.. I've had a u-bend delete for nearly 2 years and I ain't had my check engine light come on yet!!! Anyways, just a little rant.. took me 3 shops to find somebody who would do it!

 

the thing costs about 500 bucks but they got another on thats like 170 so i have to belive the more costly one has to do something good you know?

 

dont do it, it will cost less to delete it yourself and put in a highflow cat, same thing, just go that route

 

Why don't you post up links to them, and we can tell you the difference. Is it possible the 170 one doesn't have a cat?

Also, I thought you were getting headers? A lot of headers include a downpipe section as well, so you should probably decide on headers before you buy a downpipe.

 

ive been asking all around on how to link so i kinda cant right now.
