Default Downpipe question-no mods

Hello all, I have an 88 Lesabre T-Type with a 99 SSEi drivetrain swapped into it, and I got the manifolds, Xover, and downpipe coated but dangit if the downpipe isn't cracked at the flex joint. The thing is stock for now, stock airbox and pulley, and at most I may add a CAI and 3.5 pulley. Should I go with a stocker or a Hogan 3" pipe? The exhaust is stock 99 SSEi with a stock type walker dual exit muffler.

I can't see the Hogan downpipe freeing up lots of hp but it can't hurt, If you have spare money to throw around go for it especially if you can't fit headers in your engine bay.

I don't have spare money to throw around but like I said my stock 99 downpipe is cracked and I need to replace it with something, and have the options of either stock replacement or Hogan. If anyone knows of another bolt in/on option available I'd be glad to hear it. NAPA doesn't have a replacement pipe available in their catalog. I don't want to take it to and exhaust place and have them weld something in there.

If you don't have any plans of modding but the 3.5 and CAI, just get a new stock downpipe. You don't have the supporting mods for a 3" downpipe, and you will lose bottom end power, which is worse on a Series II than a Series I, as the peak torque on the Series II is higher. You need that bottom end OOMPH.

The price diff. between the stocker and hogan is close, stocker is 175 plus tax, hogan is 150 plus shipping. I'm just pissed because I didn't hear any problems with the wrecked SSEi before I took it apart, so I got the 144K OE piece coated, only to find it leaking once the T was done. It'* a really annoying sound.

If that is your case get the Hogan DP, don't be scared by people telling you will lose bottom end power. You may lose some torque but your 88 T-type doesn't weigh as much as the 99 SSEi the motor came from so the loss will not effect performance quite the same as it would on the 99 SSEi.

are you sure the flex section isnt the culprit? but id do a 3' anyway, the loss of TQ isnt a drastic as people make it sound. plus it will help with the pesky knock retard but id invest in a set of headers or power logs to complete the package.
