Exhaust

I am getting ready to do my exhaust. I have already installed an intake system that replaced the stock air box. I notice the additional air flow on the intake side but I feel the lack of processing ability due to a restrictive exhaust. So my question is this...

Has anyone upgraded their exhaust system?

I was thinking of just replacing the muffler with a higher flow muffler. I was told that doing a high flow cat was not needed by a muffler shop but another friend of mine said that I should do the high flow cat. I do want additional power BUT I do not want a loud obnoxious sounding exhaust system. Throaty sounding works for me but nothing retarded sounding! So what have you guys installed on your Rodeo's that may fit the bill? Also, is the stock pipe system good to go or should I have the entire system replaced? (I think I read some where that the pipes are too restrictive due to a poor layout of the system? I am not sure if I read that about the Rodeo/Amigo... just checking.)

Thanks all!

What did you use for an intake, I was thinking about buying the one from Calmini but have no idea if they are very good or not.

I purchased one off ebay for $32 with a K&N oil charged style filter. I have purchased the high end versions and the stuff of ebay for various cars/trucks over the years... it is all basically the same stuff... a pipe, filter and hardware. Very low tech... so I do not see a true need for the high dollar version. I am not sure what the Calmini costs... but as I recall nothing is cheap over there. The intake took 20 minutes to install... in the dark. So it is a simple bolt on. I really did not see much of a difference in performance but you can hear the intake "sucking" in air.... the stock one was ultra quiet. The intake is only part of the big picture... the exhaust is the other half. Once the exhaust is done I expect to see the advantage of the new intake come into effect. I have put the ebay link so you can see the exact intake I have on my Rodeo Sport.

Wow thats a lot cheaper than the calmini one. How does it work, im thinking i am going to get the K&N version of it. I had an intake on my old VW and while the power and torque were slightly higher, fuel seemed to increase a decent amount and it makes a really cool sound! Have you noticed any increase in fuel mileage as I am sure everyone here knows, RODEOS/PASSPORTS LOVE FUEL!

Well, to comment on the fuel part... even if the 3.2 V6 were to increase fuel efficiency by 10% (which won't happen) it would still be a huge gas hog! I love my Rodeo Sport... but I really hate the gas mileage! LOL What can you do??? I think I noticed a little better gas mileage but I have not done any real world testing on it either before or after the addition of the intake.

The intake does make a cool sound but I feel as if I lost "off the line" performance. Not that I race my Rodeo or anything but I did notice a drop in the torque. That is why I want to do the exhaust to balance out the intake/exhaust. Anyway, the company on ebay that I bought the intake from was awesome. Shipping was fast and I think they offer a package with the real K&N fliter included. At the price point it is far cheaper than most other intake systems.... and you can not go wrong with a K&N fliter. The long universal bracket that is included with the kit fit perfectly... I put 1 90 degree bend in it and the predrilled hole was the exact size for one of the stock air cleaner bolts that screw into the fender. I attached it to the MAF assombly (lower left hand screw) which stabilized the entire intake. Minimal modding to the bracket, otherwise it was a bolt in.

I am really pumped you posted taht because the calmini intake was at least 100 dollars plus shipping and I can't image the calmini filter can even touch the K&N filter.

Yeah, K&N filters are hard to beat. If you get the intake let me know how it went for you. I will also post on my exhaust once I get it done. I hope to hear some feedback from the experts on the forum so I can make an educated decision. Right now I am totally shooting from the hip on what I may do.

Have you done any note worthy mods to your Rodeo yet?

Have fun!

I haven't done anything yet, I am waiting til i get my tax return back. I am on a college student budget which equates to about zero dollars. I also have to pay a big chunk of money for a on campus parking permit.

College student syndrome.... low funds, lots of needs! Well, I will post on any and all upgrades... I am a "best bang for the buck" kind of shopper so I don't throw money around. If I see a great upgrade on the cheap (cost effective) I will make sure I pass it on.

An aftermarket air intake and exhaust wont do much for your 3.2 aside from give it a custom look and sound. The stock exhaust system and muffer are large enough to fit a grey hound bus. The stock intake is very large, simple and short. Use of an oiled airfilter will require periodic spray cleaning of the MAF. You will get fuel trim induced misfires when the air filter oil carries over onto the MAF sensor (which it will). I dont mean to get all negative on you, but I hate to see people waste cash on aftermarket air intakes and exhausts for the purpose of increased performance and economy. They almost never happen. IMO- they are good for a custom look and sound, that's it.

For the exhaust, forget about replacing the cats. Only the real early years used the restrictive type, later first gens and all second gens use ones that arent restrictive.

I put a flowmaster 50 series SUV muffler on mine. Its not loud at all, just enough to give some sound (still sounds like a v-6 though). I went with 2.25" pipe, others have used 2.5" if you can get them to do everything after the cats (including the y-pipe) it would be best. They only did from the y-pipe back on mine. I havent noticed any real difference in performance but it seems to have gone up 1 mpg.

I am thinking that the K&N intake and the same muffler you have should give it some nice sound. I dont want the fart can sound a cheap exhaust gives. I really just love the sound an intake gives, makes it very throaty. I really have to be smart thought, i need to clean up a lot of stuff before i got spending money I DONT HAVE!!!!:iceslolan
