Exhaust options

Turns out my OEM exhaust (which may be original) needs to be replaced. Have "heard" the borla is too loud for some (I have small children who will be out with me frequently) but have one on my CJ-7 which I have been happy with. Any other suggestions would be great.

Also - was told by another D90 owner to go with ceramic coated manifolds (which would make sense given I've had manifold iusses with the jeep as well). Any thoughts on them in general or specific place to source would be helpful.

What I've done and have been happy with is a custom tailpipe and a flowmaster muffler. The custom tailpipe cost me a little less than a stock tailpipe. I wanted my the tailpipe to exit straight out the back as opposed to the side.

I had a 110 with exhaust manifolds that had been wrapped and I was ammased with how much cooler the interior kept on hot summer days. If ceramic headers do the same I'd say that's a good investment.

My problem with the Borla was more that it had an unpleasant drone to it. It was also probably too loud but the tone at certain points was annoying. I only had mine on a couple of weeks before I took it off.

I've heard the same thing. How about NRP, whats louder the NRP or the Borla?

I completely disagree. I have a Borla exhaust and think it sounds great. It's pretty quiet until you get to 2500 RPM's and then you hear a nice rumble. But it's certainly not too loud, even with the top off IMO. I actually wish it had a bit more rumble.

Borlas last forever and have one on two different rovers. I would prefer them to be quieter as stock rover exhaust is quite quiet, but at least they don't rust out.

NRP if you enjoy a challenge. They will turn brown pretty quick too.

Thanks everyone - for the thoughtful input. Cost/benefit the Borla looks like it makes the most sense - just a question of whether I drive the family crazy in the process.

Brother in law (multiple past defender owner) suggested ceramic coated headers - seems like there has been some past banter on this topic, but nothing in the past few years? Seems like a good idea and would love to source if possible.

I went from Magnaflow to Borla I don't think one is louder over the other, just a different tone. At 2800 rpm every system is going to peak. I am leaning toward the overall benefits of the Borla.

You can pickup a used set of headers and have them dipped. It's the same quality and gets the job done. There are a few sets around, just search the threads going back 6 months.
