Finally got my hands on a used SRT8 exhaust set-up, pipes and resinators w/out the muffler which I didnt want. Before anyone says take it to a shop and have it done, I want to do it myself. I want to delete the muffler altogether and just run the SRT parts. So now what, I need a 2.5"ID in/ 2.75"ID dual out 'Y" pipe and a section of 2.5"ID pipe and some clamps im thinking, and also two hangers for the resinators. Do they sell stainless steel pipe local or is online my best bet to buy it?

Right now i have a Magnaflow SS catback exhaust that im happy with sound wise but I want my my WK to look really good and i think having a dual exhaust out the back will do it. I have the Laredo bumper so I think I will need to work on the exhaust tips height back there to make it look good. I was thinking of getting the trailer hitch bezel and cutting the bumper, but now looking at it i was wondering if I can cut out the bumper smaller and install a basic black trim instead. Im going to attempt the install saturday, so any ideas would be helpful.

your gonna have to buy a y pipe since your 3.7 is a single system and you will have to convert it to the dual SRT system. You will also have to have 2 hangers welded onto the rear frame rail to hang the rear tips from. I have pics in the WK section on how to add an srt system to a non srt wk. Its a sticky

Shoot Timmy...I know it would be awesome if you could do it yourself...but you're gonna save yourself a lot of time and headaches if you just take it to muffler shop, and have the fab up the y-pipe for you, weld the hangers in place and all that good stuff...I know its not what you wanted to hear....just my thoughts...

Dam I want this thing on right now, to see how it sounds. Hope it sounds good without a muffler. I cant believe how much crap i have already stocked in my basement to keep when I ever do sell this car and change it back to stock. Ughhh

DIY its not hard it's easier with a welder but you can do it with out it. you can have a shop weld the hangers in place. you'll need those done out of house but that would be it.

Dam, FINALLY someone wih the same mentality as me!!! haha. I am going to take it to a shop I went to before where they charged me 50 bucks to install this magnaflow I have on now, but if its over 100 im going to do it myself.

And the Stainless steel magnaflow Y pipe I keep seeing online is about 26 bucks w/free shipping on amazon.com. Im not familiar with exhaust shops, do they usually carry stainless steel pipes and weld them? I want all stainless, even saw some stainless steel clamps I was going to buy.

Dude, total bummer. I threw my exhaust in the trash when I put my stainlessworks on. It had less than 1000 miles on it. I would have given it to someone for $100 if they would have paid for shipping.

I didn't think anyone actually wanted those things.

Im actually saving mostly everything stock I have removed and replaced on my WK for later when I sell it I will put it all back then sell the aftermarket parts on ebay.

In the picture in the first post of this thread, the two things that look like mufflers are actually resonators on the SRT's. The muffler are actually located about a foot in front of where his piping starts, or about a foot behind the cats. They are fundamentally different from the mufflers in terms of what they do to the sound.

Mufflers attempt to baffle or otherwise diffuse the sound, resonators attempt to straighten the airflow to minimize resonance.

I know Jason. I was saying that because I chopped mine off when I had the Dynomax Bullet muffler installed in place of the suitcase muffler.





^No resonator.

It was a joke. :lol:


Thanks for the informative post for the newbies though.
Damn, dawg, you got me. I thought you were serious. Nobody likes you! :)

God, I like this site so much better than the "red site".

I just noticed you still have that plastic cover under the engine, I took mine off because when I changed the oil it would go all over the place on top of it and get all over my driveway. And what, do you clean the underside of your car too, because it looks so dam clean. lol.

I was just outside looking under my bumper, is it even going to be possible to have these tips set up in the middle of the bumper like the SRT's do with my Laredo bumper? I planned on cutting it out and installing the trailer hitch bezel, or even just installing a black trim piece over the cut edge. But now im unsure if the top of the resinators will be hitting the bottom of the car, and im stuck with the tips being below the bottom edge of the bumper. dam it.

you could do a quick fab up by removing the spare, sticking some bolts in the holes I show in my thread and hanging the resonators from thsat bolt to get an idea.....
 
#25 ·
Thats a better idea than I had, I was going to make a platform out of wood to hold the exhaust up there while I figure how and where to mount it. I took my spare out when I got these rims on figuring its useless now anyways being a diff size. I hear you can destroy a differential by running diff size tires, even the size diff between a new and used tire, and with this set-up there is about at least a 1/2" diff in sizing.

I know everyone excpet for Denny says take it to a shop, but I think installing this to fit right in my Laredo bumper will take alot of planning, which will be fun for me.

I hear ya.....I was the first to do alot of this and it took some planning and fabbing. i had no idea if the SRT bumpers would even work on the WK when i bought them. Just went on a hunch and alot of . same with about everything i have.... I hoped the SRt seats woulod fit....but really had no idea

So this will be the first stock srt exhaust with a laredo bumper then? I have only seen people do srt exhausts with srt bumpers and a dual exhaust on a WK with the pipes sitting below the bumpers, but havent seen an exhaust on a WK that comes out in the middle of the bumper. I just measured again and if i did get the trailer hitch bezel there would be too much empty space on the sides for it to look good I think, so i think I will have to cut the bumper perfectly and sand the edge smooth or get a trim for the cut edge.

I have the complete SRT exhaust minus the muffler on my 4.7 and it isnt that loud. I would think the 3.7 would be a little quieter....just a guess though

Yea, but im sure your definition of loud isnt the same as a normal person scott, Haha. I really dont know anything about resinators and how they work but I would think having two of them on would kinda be like having this magnaflow straight thru muffler I have on it now.

And because of the height of the resinators I dont think I will be able to get it up there high enough to have the exhaust tips coming out the bumper, so i might have to be stuck with it below the bumper, which I guess still looks better than mine now on the right side.

Scott, trying to find your exhaust clip to listen to it again, but i remember it sound good and not too loud.
 
#34 ·
Awesome, thanks. I must of just listened to it about 30 times right now. I KNOW the true sound and how loud it is isnt coming thru from that video, how loud is it from inside when your driving down back roads and then on the highway? Is it loud enough cops might pull me over you think? Right now im just trying to think if I want to keep my magnaflow muffler on or delete it.

Like today I heard a piece of crap car going down the road that was so loud I could tell they must of had an exhaust leak, and I dont want mine to sound like that.

Guess what im saying is I do want it sounding "powerful" but not like a car with a rusted out muffler, know what i mean??
 
#36 ·
LOL....on the highway if I turn the radio down I can here it....its a slight rumble...BUT....it really comes alive on WOT. So no...it doesnt sound like a rattle trp, leaking exhaust. I wouldnt have it if it did. I think it sounds like some of the SRT exhausts.

Im so crazy in the head I kept playing that exhaust clip over and over again while staring at my car wondering if the sound will match the car, and I do think it would sound pretty sick.

Ive come to realize that im stuck with the tips below my Laredo bumper now, because the frame is in the way for me to get it up high enough. I think the only way to have the tips high enough coming out thru my bumper is to delete the resinators with a straight pipe then cut the hangers and have the pipes almost right to the cars frame. I was under there playing with the resinators and see that they are slanted downwards, which is good because I was worried they would be seen, but because my cars lowered I think they should be hidden fairly good.

Im still up in the air if I should keep the magnaflow muffler. If anything I think having the dual srt 2.75" pipes back there it would make the exhaust louder than my single 2.5" pipe right now. Any thoughts?

Yea, I know. But hey thats what I do, think about things before I do them. I very close to installing it now, just want to figure out if I rather leave my magnaflow muffler on or delete it. Took me a few days to accept that the tips will have to be below the bumper, but think it will look pretty good now.

So what is it your saying, you think I should run 2 magnaflow bullet style mufflers with theses srt resinators and tips? Not sure why id go out and buy 2 more magnaflow mufflers when I already have one on right now, and wouldnt having 2 make it sound less loud than it is right now?
