Time has come for me to ditch the OEM exhaust manifold... cracked finally. It is an 87 so it lasted a long time.
Looking at the Dorman for about 165 bucks anyone run this manifold. We are kinda limited on what is available for the 87. Since it is Renix. I don't really want to spend over 200 bucks all I am worried about is at least OEM performance or maybe a tad better. Been googling all morning so now it is time for yalls opinions.
Thanks

I currently run a Pacesetter header/downpipe, stock cat, flowmaster 40 muffler, then 2-1/2'' piping that dumps over the axle. I like the sound, but I want it to be louder. Im thinking about getting a 2-1/2" high flow cat, 2-1/2" cherry bomb glasspack, then having a pipe made that has it exit on the passenger side under the rear quarter panel(since I have the cut/folded lower quarters).
Anyone have this exhaust setup? or have the exhaust tip in the same area?

Studs and nuts.
I'm working on my 1997 Cherokee and it turns out that my exhaust manifold is cracked down near the collection point where all the tubes come together. I'm told this is a common problem. It doesn't look too difficult to get this manifold out, however I'm concerned about the condition of the studs and nuts holding the manifold on. They're old and rusty. How concerned should I be about them braking when I try to loosen them? I ask because most of my experience is with Turbo cars and they tend to be very brittle from all the heat.
Thanks!
Thanks!

Just realized I put this in the wrong section but I can't seem to delete the post?
Sorry about that. If an admin wants to move this to OEM questions it would be appreciated.

Have a question about noise.
On my previous XJ i had a FM 44 offroad muffler with a turn down right before the axle. It sounded awesome and was nice n loud, but got annoying on long trips(that drone). On my new XJ i wanna do an exhaust system with a tail pipe coming out the oem location. Will it be a good deal quieter if its coming out the back compared to the turn down style?

Cherokee XJ Exhaust question
To get my Jeep registered in CA, it had to pass a smog check but before doing so, I discovered the PO had removed the check-engine bulb. After replacing the bulb and clearing a former code for the #1 O2 sensor, I found that the exhaust pipe, where it connects to the flange at the collector pipe, has what appears a dent on both sides. Is this a factory thing for clearance, which doesn't seem necessary, or the workings of a previous idiot.
I am just wondering if this restriction is what was originally causing the code to activate.
Any insight would be greatly appreciated.

44, 40, and 10. The 40 may be your best bet, I don't think it's overly loud but it does sound good. 44 is pretty aggressive and the 10 will try and rip your eardrums out
