Re: Video of Magnaflow ack on my 3.7.

If I were anyone with a 3.7 i'd just go out and get a cheap straight thru muffler and clamp it on, I spent $427 for this and could of gotten the same tone much cheaper. Just my thoughts.

Re: Video of Magnaflow ack on my 3.7.

The first two revs were to about 2 grand, then I reved it up to about 5grand. I did notice the few "spurts" or cutoffs, whatever its called. I think thats only cuz I wasnt actually driving, I never have that happen while driving, and have had it past redline many times on highways gunning it WOT.

Re: Video of Magnaflow ack on my 3.7.

I cant wait to get this srt exhaust on and see what it sounds like. Im thinking it will def be more "throaty" since im deleting the muffler. Other than that I have no clue what to expect it to sound like.

Only reason I bought this srt set-up was for the dual pipes that go over the axle, since I heard they are kinda hard to fab up without hitting, and got it at a cheap price. I would be up for deleting these big ass resinators also. For the price of polished tips alone is what I spent on this srt set-up.

Re: Video of Magnaflow ack on my 3.7.

So talking resinators, what exactly do they do and how do they work? I have seen a cut away of my Magnaflow muffler, where its just straight tubing with holes in it surrounded by some type of packing material to "muffle" the exhaust, what does a resinator look like inside? Im just trying to get an understanding of them.

Thanks man for the clip, I am still on the fence on whether to go with magnaflow or a flowmaster for my 3.7

Honestly because of the major price difference I would just get either a Magnaflow or Flowmaster muffler and a nice polished tip and leave the pipes stock to save alot of money. The price of a bolt on Stainless Steel catback system is insane looking at it now.

Cool man, and yeah thats what I had already planned to do, I just want the sound and could care less about the small if any performance gain of a cat back anyhow. I am still trying to find a shop that can pull off dual tips like Marlin and keep the spare in there for now too!

Well then your prob talking alot of money for what Marlin did. Thats all custom work and takes alot of planning and materials. Before I got my srt setup I was thinking about tapping off the tail pipe after the axle and putting a 90 degree pipe to send another pipe over to the drivers side. But since I got these srt rep rims my spare tire is useless to me, so I took it out anyways. Ill keep this magnaflow cat back for when I get rid of my WK down the road to change it back to stock and put the spare back, thats unless I sell my magnaflow to someone that will send me there stock set-up to put back on later.

I have the K&N CAI also i got installed at the same time, I think intake and exhaust go hand in hand to get the best performance. I say just get a straight thru muffler and a nice tip because of what i spent alone on the whole catback system, $427, I could of bought just a nice muffler for about $80 and tip and got almost the same results. When I first got my WK I just went to walmart and bought a $10 stainless steel tip that slides over the tailpipe which looked 100% better than the stock look. Just replacing the big ass stock muffler with a nice small aftermarket will give you great results IMO.

Im just saying for the cost of a whole stainless steel catback system you can buy a nice muffler, tip, and CAI for the same cost. The stock pipes arent stainless so you might have to replace them later on down the road, but just replace them with cheap aluminumized steel again and wont cost alot. Me, im frugal so I like to stretch my dollar for the most I can get.

Well, here's my 2 cents about it. I do like the K&N CAI but I notice im cleaning the dam thing every 2 months, so maybe look for a dry filter. Just dont get the intake where you use the same stock airbox, get a cone type filter and a new plenum tube and that will be plenty big enough to get air to the motor. As far as mufflers, I dont know alot but to narrow it down for you i would def go with a stainless steel so it lasts you the life of the car, I would also look for a straight thru design rather than the chambered ones, like Magnaflow or Dynamax or even Pypes has straight thru. Dont waste money on a polished stainless muffler since no one will ever see it for the price difference. Im looking thru the Jegs catalog I have and can pick out a few mufflers I would look into trying, all of them stainless and for under $73.00. As for a new tip, i've seen them on ebay for like 30 bucks plus shipping, OR, do what I did at first and get the walmart polished tip for 10 bucks.

Like i said earlier, yea your keeping your stock pipes and will prob have to replace some things down the road but its much cheaper than a full SS catback system. Me, I had money to burn so i didnt care and wanted a system i'll never have to replace hopefully, but now look what im doing, installing the srt system instead so I wasted my money on this magnaflow catback. Oh well, live and learn right?

I have the same magnaflow too and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 16632. Also some of the forum sponsors usually have a sale going on. Either way its a great exhaust system, sounds great, and very easy to install.

Thats about the price i've seen them for. I got mine off hotexhaust.com for $427 shipped, paid $50 for a shop to install it but never bothered sending in the warranty card. So far so good, though I noticed some slight rusting/discoloration at the welds. Maybe its just oxidation. There's really not alot of catbacks for 3.7's to pick from, so Magnaflow seemed the best IMO, and very happy with it. Just been busy with work and trying to move lately havent justified spending the $100 or so to have this srt set-up installed yet, im cheap.
