Default Free up the down pipe

I want to free up the exhaust after the headers. ie. the large dimple in the down pipe. Is there a better one available commercially or do I go to my local muffler shop. We're talking about a '90 Renix 4.0.

i got a walker down pipe. it does not have the dent or the silencer. but it is a crinkle bend. i was not able to find a mandrel bend without buying a header too. you could have a shop bend u up one to. i forget the price. i think i paid under 60. for it. if you need to know how much i do have the receit somewhere.

Thanks for the reply, I've been searching the various net sites and haven't found what I want yet. I know Pace Setter is the only set of headers available for the Renix '90 and since the engine has 198K on the clock I may go this way.

Walker is pretty thin from what I'm told, but I've never bought one, do you like yours?

You lifted? That's why that dent is there - to clear some suspension component (UCA, I think.)

If you're not lifted, your new pipe will "self-clearance" at full stuff. Reports from the field indicate that a 3" kit is the minimum needed to maintain full profile there without clearance work.

He's saying that if you flexed yours your upper control ARM would hit the pipe unless your lifted 3+, but I skimed it so ha ha

Not entirely true. If you have the shop bend a pipe in two 45* angles rather then one 90* there should be enough clearance even on a stock non-lifted XJ, or so I've heard from Cruiser54 and a few others.
