Well I got a Dynomax exhaust for my truck awhile ago and figured alot of people probably got them too when they had the discount not to mention they aren't too expensive anyways.

I got the #39315 1998 - 09 Ford Ranger 2.3L, 2.5L, 3.0L, 4.0L Ex cab/ Short Bed. Single Exit, 2.5" pipe with 3" angle cut tip. (It says stainless steel but the one I got was Galvanized or Aluminized) And came with a super turbo muffler instead of the welded.


This is pretty much what I got, Except with a Super Turbo Muffler and U bolt clamps.

I purchased it for 200$ from Napa in Alaska, and missed the 75$ rebate by one day apparently. I opted for the really slow shipping which only took 3 weeks and didn't cost a penny extra. The system came with everything I needed: The donut gasket for the coupling, intermidiate pipe, Super turbo Muffler, 2x clamps, and the tail pipe with tip. The pipes are pretty good quality as is the muffler and stuff, the tip is polished steel andactually part of the pipe.

Installing it was easy as pie! I am pretty mechanical but I have confidence that even a beginner could do in your driveway with just a basic set of sockets, WD40, and a hack saw (maybe, i used one to remove the old exhaust faster.) It took me 30 minutes to do it with a lift and everything, 20 to remove the old rusty bolts and 10 to get the new one set up. I found I could only get the muffler on one way but others i talked to could get it on both ways... or just the opposite way only. The all you have to do it line up the pipes put the hangers up clamp it down and blot it together. I also reccomend putting some high heat silicon gasket sealer around the donut to make it perfectly tight. After that just start up and go. It technically should take about 1000 -3000 miles for the muffler to properly break in but I found that a good continuous 200 mile run will open it up just fine. Also to make it last as long as possible I put a couple coats of black High heat Header paint over all of the pipe and muffler to make it last through the winter salted roads.

Heres some photos and a video right after i installed it.








Heres how it sounded after the first 10 miles.

I plan on getting another video tonight to update how it sounds 5000miles later.

I have been looking at this kit and plan to buy in the next couple of weeks, the 75.00 rebate is good until August 31st here. Thanks for the post, now I feel alot better about installing it myself. After installation I'l jump on here and throw in my two cents :icon_thumby:

I installed this on my truck and I like it a lot. It is a lot quieter than no muffler at all, but has a little rumble to it. I got it for a little over $100.

I dono what is up with Napa's site, they have the regular super turbo for 294 and the welded ultra flow system for 229... something isn't right. I would have returned it and asked what I paid for. The aluminized pipes rot out rather quickly. I've put up a super turbo cat back only to have it rot out in 3 years. We'll see... I think I'll be buying a system this summer... damn you for posting the info about the $75 rebate :D (the rebate form says you get a CHECK... it better be a check, I'm sick of CARDS) I think I'll be going through Summit, shipping and lack of sales tax comes out cheaper.

Why not jump now? Before it is too late to buy it. I am also interested with it but I am saving for it. I hope that I can get it sooner. :D:icon_thumby:

Just did my wife's Jimmy with the 4.3.The Dyomax kit I got from Jegs for $134.00 and it bolted up real nice. The sound is pretty much stock (but she is not big on sound) but she says it seems to have a little bit more power.

In Arizona? Probably 20 years. In Michigan? Probably 20 minutes. Depends if you see a lot of snow and salt on your roads.

EDIT: same goes for any aluminized exhaust. If you want your exhaust to last, get stainless steel everything.

With the deal going on for dynomax I'm having a hard time not getting one, but concerned that its aluminized, and with the salt.... how long ago did your dad install it? How's it holding up?

Yep! So basically $35 for a cat-back. This is what I'm struggling with! Just hate to install it only to have it rot out in 3 years because of our salty winter roads.

sadly we just put it on the truck this spring, so it has yet to go through a winter, but i have noticed less appearance changes in the 5 or so months he has had it than my Gibson had in the same amount of time. The Gibson is not destroyed yet by any means, but you can tell the difference in appearance over last year. im thinking you would be good for at least 3-5 years on an aluminized system, i think they (dynomax) have a stainless option for like $10 more, but that only covers the muffler. :annoyed:

Thanks for the review. Unfortunately I have to replace the gibson system that was on my truck when I got it. The muffler is starting to rust out (only took 11 years), and the inspection guy won't pass me. Even though we don't have emissions in this county.
