Does he have/will he be using a mandrel bender to bend the exhaust? He doesn't sound like a performance shop, so that would be surprising. If so - sweet. If not - it would be pointless. I looked into having a mandrel bent stainless 3" system custom fabbed and it was pretty costly.
If he is talking about crush/crimp bent pipes(whether made to bend or not) you will end up with an exhaust that flows no better than any 2.5" system. (Just a note for anyone looking into custom, really)

 

Oh no. We're country, but we ain't that country. He's got a real nice shop. Clean paved floors and everything.
Yes, he has a mandrel bender. The guy know his business. He could do ya a work of art musclecar exhaust. Most shops around here could. It's just I have the same problem as Word down Kentucky way. There is NOBODY driving performance front wheel drive cars around here. I never see other SRT-4's. The dealer I bought the car from has never even done a stage anything upgrade. To say these cars are not popular here is an understatement. If I had a Mustang/Camaro/Firebird I would have no shortage of local talent to use. My SRT-4 is usually the only SRT anyone around here has ever seen.

 

Sounds sweet.

Hey man - sounds like your "country" shop is a lot better than most around Philly. Mandrel benders are hard to find and expensive around here. I was quoted more like 900 for a mandrel bent stainless system with dual muff's. What muffler are you thinking about using?

 

that is so sad in hawaii i see a ton of stis evos and srt4s there a dime a dozen here.

 

my roomate has a custom 3", 3" intake, 60mm tb, e01, emanage and i have catless dp w/borla 2.5", k&n 2.5" and our other mods are the same. we run from a roll and i pull him, his car should be back from the tuner tonight and it should be a different story but to stick with topic i run just as good if not better with my set up than he does so take what you will from it. my full system cost me $345.00

 

Well the thing is, sound level and quality is important to me. I want flow but I dont want loud. If I could run a hooker aerochamber like I have on my Dodge Truck, that's what I would do. They flow, they sound good and are not obnoxiously loud. However, they do not come in a "bullet" or single inlet, dual outlet configuration. I do also want to have dual tips because the valance already has the cutouts and because it's kind of an SRT-4 signature thing. I, like PSI, am not a big fan of the whole fart can look either(though a have heard her car on the video clip and it does sound nasty)(good nasty) but it is also a bit on the loud side. I am thinking, as the muffler guy suggested, of running a bullet like a dynomax in the stock location and doing the dual tips after the axle. This is both good and bad. Good because it will be easier for him to do, and I would only be buying 1 muffler and 2 tips but bad because I am quite sure with a 3" pipe and a bullet, it will be too loud. PSI Chicks dual fart cans may have the edge on quiet. I dont know how effective 2 bullets inline would be. There are also oval section mufflers with outlets on both ends like a stock Camaro setup or the one that HP racing shows in thier ad. I was told to stay away from HP though. But being that this is going to be custom and some time away yet, I can shop and mix and match. I will probably go with an off the shelf DP like needswings or maxfab, I will also be going catless, I can also get my muffler/s from anywhere and have the muffler guy fit it in.
So to answer your question, I don't really know yet, anything is possible. About the only thing I'm sure of is it will be 3".
