Another exhaust thread

My 2.7 exhaust is making a lot of noise lately, as though it's leaking. It actually sounds pretty cool in my opinion, but I've definitely noticed a small hit in MPG's.

First off, I was wondering if there's any one spot I should start looking for a leak. I've read a few things about the front resonators leaking, but I'm not too familiar exhausts.

Secondly, my cousin's a pretty big greasemonkey with his Jeep, and he pointed me to a local place that sells Cherry Bomb exhausts. I looked on their site, and they didn't have one for a 2.7l Intrepid, but they did have a kit for a 2.7l Charger...For a dual exhaust, I was wondering what kind of kits were available, or if the only option was to go custom.

There's no aftermarket kit for an LH. If you want factory duals, Special exhaust is the way to go. But if you want something else, like I did, go custom. My 2.7 sounds great with my system.

I have cat back exhaust. 2 1/4" downpipes running to a Magnaflow 2 1/4" in - 3" out Y pipe. 3" stainless all the way back to a Magnaflow single 3" in - dual 3" out, exiting through dual polished aluminum Solo SS exhaust tips. It ran me about 400 bucks and everything had to be custom made.

A lot of people replace the single in/single out rear muffler with a single in/dual out Magnaflow or similar muffler and just add the pipe for the right side along with new tips.

$400 including labor/materials doesn't sound like a bad price for Will's setup.

For what it's worth , The crossways muffler rotted out on my 02 ES so I put it on stands yesterday in the garage to see what I could do. I cut the old muffler out and tried to
fit a replacement but that wasn't going to work with out a lot of fabrication.

So I welded a 2 1/4" straight pipe in place of where the muffler was . I still have the OE
rear muffler / resonator assembly which is surprisingly solid.
The car is noticeably throatier but not as bad as what I had expected. To cruise at 60-70
mph with the windows up , you don't hear that much difference.

Again ,,, just my opinion, I may or may not leave it that way.

Here is a nice thread
https://www.dodgeintrepid.net/showthr...t=dual+exhaust

if you look at the first pic that's essencially what I have except I have the OEM resonator. I bought a flowmaster 80 (Single in, dual out) from Kijiji for $30, removed the 2 mufflers (one before spare wheel well & one at end of car.) then went to a muffler place and the custom fabricated two tailpipes for $100.

Weird...I was just thinking of bumping this thread myself. I got pulled over last weekend for being too loud on acceleration. Are any of the above options in the thread 'good enough' to keep the proper back pressure in the whole exhaust system?

I find I have enough back pressure. As I said, I've got OEM right up until first muffler by the trunk.

It's kind of a crap shoot when it comes to having enough back pressure.
When you loose power climbing a hill , you've gone too far.
We're only talking 215 ci's here , so you can't relieve it to much.

Could do what i did, chop both rear mufflers off beside the tank and have a single pipe out the passenger side. Surprisingly dose not drone much and it gives a mean tone when you need it too. https://www.dodgeintrepid.net/showthread.php?t=291474

It may be just a coincidence , but after a couple hundred miles on the freeway at 70 mph, my check engine light went out by itself.
The car usually sets a po420 cat code roughly every few weeks and I've never seen it
go out unless I plug in my scan guage and reset it.
This car is border line too loud for me , but the pipe is cheaper than a muffler for now.
