Exclamation 3.5 Exhaust question ***3.5 guys, look under your car!***

I looked under my 2002 ES to take a look to see if the rear ending I got yesterday did any damage to my car, I found no damage but I did find something really strange.

My exhaust system has a large pipe from the engine to the muffler, but the pipe exiting the muffler to the resonator is MUCH smaller and is not mandrel bent. It seems really wierd that DCX would spend all that cash on a nice exhaust only to restrict it badly at the end.

Ther real questions here are: Why did DCX do this? How much does this hurt MPG and power? And, if so, how much to get a mandrel piece to fit it?

Does the R/T have the same thing or is this an ES handycap? 300m, LHS and Concorde LXi owners, what do you see?

We may have a new cheap power upgrade!

look again, you will have the restriction if you have OEM exhaust, all 3.2/3.5 cars have it

this is the bend he is talking about



I wouldn't go through the hassle of removing just this one piece, instead save your money and do an aftermarket performance muffler setup in the future

I'll be damned, have to take a look tonight. Oh, I believe you... I haven't been under that part of the car, but I know the exhaust is still the OEM set up so it must be the same.

Somebody thought it was a great idea to save a frickin' nickle and we all get a kinked exhaust ?!

the kink was put there to add clearance for the rear suspension, I'm sure it was designed by the same geniuses who put a ground strap on the exhaust piping

I already have an aftermarket setup so I guess I can't check. Interesting though.

And what is this ground strap on the muffler piping thing?

Yep, they are all the same, including the Special left side. Interestingly though, the right side is not only mandrel bent, but is attached to the centre muffler with a flanged fitting instead of the slip fitting that the left side has.

Joe's right - I can't see that making a big difference. Save your money for a real upgrade ...

I think i'm going to try and solve this problem and see if i can bolt up the exhaust i had on my 1st gen 3.5. The exhaust tunnel seems to be the same and the exhaust look identical so i guess we'll see.

After I got my new exhaust installed, I noticed that strap just hangin there.

What is it supposed to ground?

Right now, it is just tucked up over a pipe so it's not flyin around.

Thanks!

Question Help me choose a muffler!

I'm now thinking about simply upgrading the muffler now. I'll upgrade the main muffler and either upgrade or remove the last resonator. The problem is, I have no idea what muffler to get or where to get mandrel bent pipe.

I'm looking for that subtle rumble, not too loud, but not almost silent like my current exhaust. I want a smile on my face when I put it on, you know, not asking my self "what have I done?" after I find out it's too loud, and I also want a full bodied sound, not raspy or droning.

I want a person with a bit of mechanic experience to know that I've worked on my car just by listening to it, but I don't want everyone to know I've worked on my car, if you know what I mean. Stealthy performance is a beautiful thing and I'm not about to ruin the surprise that I have for the local high school rice burners! (most have NO IDEA how quick a 3.5 is compared to a 1.6 civic!)

I guess it goes without saying: I don't want that redneck truck sound or that GOD AWFUL ricer sound, anything but the ricer sound!

Oh, last question: How restrictive are the resonators? Should I keep the one that's just after the cats?
