centered inlet muffler? Is it needed?

So today I was going to get some exhaust work done. 2.25 inch piping with a dynomax super turbo mufffler.
However, the guys said that my muffler cannot be used.. said they needed me to get a centered inlet. They showed me how the stock piping is centered and how the muffler is off, and were very nice. Told me if I get the "correct" muffler they will gladly install this and the piping they had.
My question, though, is that I know a few of you were using the ST muffler. Do they make them with a centered inlet, or is something wrong?
If you have pics of your muffler, please post 'em. I'd like to get this all figured out as soon as possible as I am running muffler-less due to a big rust hole haha.

Are you serious? What kind of n00b exhaust shop did you go to? They should be able to weld up anything.

HAHAHAHA
Go to another shop, those guys are idiots. If you had a center inlet muffler then maybe I could see them sending u away as the bend is abit harder, especially if you are lowered. A offset inlet that faces the driver side is actually perfect, the stock exhaust has this offset as well.
Different shop.

not to mention center vs offset on a muffler is like a 3" difference. theres more then enough room back there to come up with a measly 3" space.

This is what I thought... I figured that it shouldn't matter. I think they were being lazy.. didn't want to fabricate up a piece that fit.
But they had a good price for me on an exhaust... $225 installed for 2.25 inch.
edit:
this is what mine looks like:
and this is the one they want me to get:

i just replaced my center in center out magnaflow with the same super turbo you have. i didnt modify the exhaust piping whatsoever and it fit without any real problems. the only downsides i see are the tips are pretty close to the side of the car, and the muffler is rubbing against the tow bracket. when i get some hangers welded on and its hung properly that shouldnt be a problem thow. ill go grab some pics for ya
sounds nice btw. not too loud but still aggressive. almost no cabin drone compared to my magnaflow.

You should put a tip on it so that it doesn't look like a piece of exhaust tubing just sticking out

ya thanks for the "tip". lol i just spent my last $75 on the muffler. im still thinking of replacing my resonator with a bigger one or trying something completely different. when i get my next paycheck i plan on getting a tip put on and hangers welded onto the muffler. its definitely alot quieter then it was before but i want to try and bring it down a bit more.
my old setup was cat === resonator === magnaflow
im thinking of trying cat === resonator === dynomax === magnaflow
if i can make that fit it would save me from having to buy a new resonator or getting any welding done. im gonna TEMPORARILY duck tape my magnaflow onto my dynomax tomorrow and see how it sounds. if its quiet enough and sounds right im gonna go ahead and do it permanently. that is if i can make the offset muffler fit underneath without major alterations of my current piping,

So today I went around a few places figuring this out. Oddly enough every shop I went to said it wouldn't fit/wasn't advisable to fit.
The last place I went to was a place that my uncle recommended. They told me that the Muffler COULD fit in, but the reason it was not advisable was due to the amount of work to get it in. They also said it would hit off stuff (like the tow bracket and maybe the rubber mounts).
So I talked with him for a bit and he told me that he wants to take the car for the day to check it out. He is going to look at the stock piping size of the BP and figure out the best route for a cat-back system. He was very knowledgeable (like he told me the reason for the little low end power is due to my exhaust being rusted through..) and told me he is going to try to get the optimal piping size and figure it all out.
Told me it's probably going to be 425 dollars installed. This is with full custom piping and muffler (though not sure what muffler).
Also this is not set in stone. He just wants it for today to get it up in the air and check on some stuff (like for piping size and stuff)

$425 is a decent deal for quality work, IF its mandrel bent and includes a catalytic converter and decent muffler. i paid $225 for my custom piping and welding but i supplied my own muffler, resonator and catalytic converter... cat was about $65, new muffler was $75 and the resonator cost me $30 off craigslist so i paid about $395 CAD total for 2.25" crush bent aluminized steel catback. if its just piping and muffler with no cat id want mandrel bent stainless steel and a high end muffler for $425...
to make the offset muffler fit properly is easy. you just need 2x45 degree bends facing the opposite direction after the pipe clears the axle, before the muffler. that give you 2-3" more clearance from the tow hook which is plenty.

or you could easily clear the tow hook by pushing the muffler back another 2" and using longer tips to clear the bumper. if you look closely at my 3rd pic the muffler is only close to the tow hook at the very edge of the casing, pushing it back an inch or 2 would give you more then enough clearance.
im trying to get the muffler to fit under my car where my resonator is which may be another option for you as you can just run a pipe straight out and have no problems with the tow hook. im not sure if this will work or not. i have to get under the car and take some measurements but from what ive seen in some pictures it looks like it may just fit. ill let you know what i find out...

yes this would be Mandrel bent, though it's only the muffler and not the cat converter (at least I don't know if he's getting a cat)

ive got some bad news. it wont technically fit properly. theres not enough room by the cat, 6" or slightly more is probably the widest muffler you could fit under the car in that spot. the 2 45's wont fit either. the pipe would rub on the spare tire well or something else in that area. if you look at this pic

you can see the muffler in relation to the frame rails. the muffler should sit beside the frame rail under the heatshield. this is ok if your muffler sits slightly lower then its supposed to like mine, its high enough to not have any clearance issues but its low enough to not bang on the frame rail. it also doesnt and cant really sit centered under the proper hanger mounts as the muffler is pushed to the side from the offset inlet, if it did the exhaust pipes would be touching one part of the car or another. however if you hang it like mine and push the muffler back 2"s youd clear the subframe, the tow hook and not have any rubbing. its not "proper" but it works...

okay so what he said to me makes sense. Then I'm on the right track!
Tomorrow we'll see what they do!
