Adding Headers, and Exhaust to my 01 5.2L I see the stock crossover is a heated and bent stock configration, with the wrinkles on the inside of the bend. Anyone out there have any experience with an aftermarket crossover with Mandrel bends. If there is one, does it help in performance? It seems to me, if you add the headers and the exhaust, the stock crossover is now the weakest link, and would cause some exhaust restrictions.
Is there a bolt up direct replacement to the stock? Does it make a difference?

Tanks,

I'm thinking about headers myself. What kind of headers are you going with? I've been looking at edelbrock, but I'm not sure yet. I also have the same question about the crossover/ y pipe on both my durango and my ram..

I went with edelbrock headers and I am very happy with them. Here is a picture

As you can see they are the shortys which bolt directly on to the stock exhaust which I have also chenged to the Magnaflow stainless steel cat back system. I still have the stock 2 1/2 Y-pipe, but everything else is brand new and sounded absolutely WICKED! I had to put a glasspack in before my magnaflow to quiet it down a little!!!

Pressurevac, I had another question for ya. Your cai, what system do you have? Also do you have a rubber gasket at the throttle body where your cai meets?

well up here in Canada I found the headers on sale for $350 cdn, so thats like 275 US. My CAI is kinda a custom piece, and I am not sure which rubber gasket you are meaning? The one between the pipe and the plastic air box? Or between the air box and the Throttle body?

Absolutely not- just a direct bolt on - VERY easy!!

The gasket between the t.b. and the air box.

That gasket is a thick paper type of material, not rubber or cork.

Just wondering!

I see conversations on adding headers, exhaust, but no mention of the corssover from the headers, to the CC. Anybody have experience on a better than stock crossover, or is ther any difference. It seems to me with headers on, and exhaust on, both providing better exhaust flow, the crossover, with it's wrinkles in the inside curves, would slow things down a bit. Make sense to anyone else?

Seems to me that that would be the case - have you tried the Magnaflow forum in the sponsor section?

Here's a link: MagnaFlow.com

I have mid length headers on the jeep that has an aftermarket y-pipe. it took the pipe diameter from 2.5" to 3". Mine also had a huge crush zone on the passenger side where the oil filter is. This robbed alot of power from the jeep. I put mid length headers on and a 3" magnaflow cat and cat back system and picked up .7 seconds in the 1/4 mile. This was done a couple months after replacing the stock 2.25" cat-back with a 2.25" borla kit and a new catco high flow cat.
