I'm looking for a nice loud but not too loud exhaust for my jeep cherokee. Don't want flowmaster something else any ideas

I couldn't be happier with my magnaflow. Not to loud, but sounds great. Got it in the vendor section from Mudfrog. I believe the title of the tread is "New Exhaust Kits" or something

I run Rusty's Flowmaster 40 system. Very durable in the ROCKS!!
It was VERY loud on my '88 with no Cat
Sounds much quieter on my '99 with a Cat.
My son runs the Dynomax on his '91 with a Cat and its a little throatier than Stock.
Do you run a converter or strait pipe? Makes a big difference!

Cenverter its a 96 I was thinking about putting a pipe through it to make it stright

That will make it much louder whatever muffler you use.
Make sure you have no emissions inspection in your locality!
'96 and above are OBDII and unless you get an O2 simulator for the rear O2 you'll get a check engine lamp lit up!
(P0420 Catalist Efficiency Low)

Was thinking of doing straight pipe on my g/f's 96. Was just gonna thread the new piece and run the o2 sensor in that. Would that work?

The Converter uses O2 in ithe catilizing process and the front and rear O2 sensors read differently when the Cat is working. With a strait pipe the readings will be the same and the ECM will know the cat isn't working and set P0420. Check Engine lamp will turn on. A sensor simulator basicly sends a false signal to the ECM to fool it.
I found O2 simulators on line a couple years ago for $40-$50. They are not leagal for street use.

Thanks. I'd been wondering about that. I appreciate the info

white99xjclassic

How much effect will that have on how the motor runs would be my next concern of I don't run the simulator or the cat?

hunter9109

That's what I was going to ask about the o2 sensor if it would do anything to it but it will thanks

Tampering with the catalytic coverter is a federal crime, not just a local issue. Just leave the damn thing alone and nobody gets hurt.

hunter9109

What they don't know don't matter I've done it before and Im going to keep doing it

white99xjclassic

Well,yea,if ya wanna do it the easy way. We're Jeep owners though,we do it the hard way by nature. Its in our blood. Lol. Seriously though,Summit is only like a half hour from where I live so I'll probably just put some pennies back and take a trip up there for a cat and maybe a good series 40. Been seeing alot of good comments about them on here.

To remind everyone before a mod closes this thread: It is a violation of federal law to remove a cat or alter one, my point being it is also against forum rules to discuss illegal activity.

With the o2 sensor being where it is im not doing it. Im not going through all the problems that go with it to pass emissions
