I really like the looks of this exhaust system part # 17398 http://www.flowmastermufflers.com/s...d=3847&ab=17398&recordID=&vehicle=&orig=17398

I've done some searching around and I have not found any pictures and the only video I found on youtube was inside the dude's garage which to me doesn't really do justice..Any advice on this exhaust system? and/or pictures of it installed.

I just got this truck a little bit over a week ago and it's too quiet lol. Anyways, let me know what you think about it and any input will help me decide if I should go for it or not. Thanks in advance

I had a 2005 before this truck im pretty sure thats what I put on mine the one I had bought was a 40 series not sure what one that is I personally thought it was to loud in the cab sounded great outside I think It would have been better if it exited out the rear then it would not have been so loud in the cab atleast thats what I was told . dont get me wrong I love loud but I like to beable to talk without yelling at highway speeds . Good luck with your choice.

I'm not a big fan of rear exit exhaust I dunno why, all my vehicles have either been side or dumped. Last truck I used to drive was a 98 Silverado and I did a true dual side exit with 40 series and to me it was perfect so I think I can get use to it again. I even thought it was quiet lol. I guess i'll be the guinea pig for this system since no one seems to have it

Oh yea for sure i'm posting videos, pictures and a review. It is a Super 40 series, that comes with that "Deltaflow" technology which they claim to help keep the cabin noise down a bit, we'll see.

Flowmaster Muscle Truck Exhaust

I currently am running this setup on my 2003 Ram 1500 5.7 Hemi. I originally put a Flowmaster series 40 - 2 chamber muffler with dual pipes going out the back. It sounded great but I had problems with the tail pipes and need a change. I thought the series 40 was rather loud although it sounded great outside the cab so I opted to go with the series 50 HD American Thunder setup with the dual pipes existing in front of the passengers side rear wheel. I thought this would be quieter, NOT!!!! The 50 series has a different sound, deeper and more throatier. There are 4” chambers in this muffler which flow incredibly well. I had a noticeable increase in performance but this thing is loud. I don’t mind loud, my ’77 corvette can’t be too loud as far as I’m concerned but this is my daily driver. I picked up a 3” glass pack to use as a resonator in the hope to quiet it down a bit. I want to install it in front of the muffler but I haven’t figured out just how to squeeze it in where I want to go. The fit and finish of this kit is great but the chrome tips could stick out a little further. I feel the exhaust comes out too close to the rear tire. If I had it to do over again I would call Flowmaster and have the rear tail pipes custom built to extend out 3 more inches to better clear my running boards. Definitely different in appearance and sound, it does turn heads.

Food for Thought

Just as a side note, I didn’t order the kit from Flowmaster for the install. I called Flowmaster and ordered the tail pipe section only (part number 16419). (You may need part number TB499, the head tube extension, if you are removing the stock muffler for the first time to make it work. I fixed this with the first flowmaster I installed.) They gladly agreed to my request and only charged me around $100.00 for the tail pipes. Originally I wanted to use the 40 series muffler I already had but it was a 3” center inlet with dual 2 ½” outlets. The “American Thunder” tail pipe section needs to be installed with a side inlet so the hangers line up and the pipes stick out correctly. I could have taken it to the muffler shop and had the head pipe modified or the hanger relocated to make it work but I really didn’t feel like giving them money for basically nothing. I wanted to switch to the 50 HD series anyway and found one on E-Bay for $90.00. The cheapest I found the Flowmaster 17387 "American Thunder" kit was from Amazon for $285.00 or so. I picked up some muffler clamps from my favorite parts store and I was on my way. I saved a few bucks in the process and it was a super easy job.

Sorry, 4th of July got in the way of posting response. Don’t mind my dirty truck but here are a few photos of the exhaust.
Awesome, thanks for the pics. I really like it...Read what WaybackInc said, did you need anything other than what it came with? If you do it's no problem I know how to weld and at the Auto hobby shop here on base we have welders

Welding

I'm not keen on welding exhaust together. I much prefer clamps, they are more forgiving if you chose to change things in the future. I still think you can assemble this configuration cheaper by parts other than the whole kit. If you are worried about not having what you need to complete the assembly go for the kit. Flowmaster has a wonderful support staff to help if you run into problems. With the kit and a saws all or hacksaw for that matter it shouldn't take you more than 30 minutes or so for the install. A friend once told me a hacksaw builds character. I must be one heck of a character by now!

Well, I'm stationed in Utah so the winters are sometimes bad here but he past 2 have been pretty mild. I know the exhaust system is aluminized steel so I see why they rust, but wouldn't applying some sort of anti rust spray paint like this one http://www.princessauto.com/shop-garage/paint/spray-paint/8057382-flat-black-anti-rust-spray-paint Might do the job?

From my experience any painting to your exhaust pipes is a waste of time, it usually burns right off. i haven't tried high heat engine paint? It may work.
