Exhausts with twin cats?
 
OK, I like my rusted out magnaflow exhaust.
Sounds great at the track at WOT, but driving on city streets it's obnoxious.
It sounds like a rusted out muffler. Go figure.

Any suggestions?
I will probably get another magnaflow if I can find the part number.

I have a Magnaflow I bought from ebay. It is stainless, but it is not a high grade stainless so I expect that it will eventually rust too. The tubes are 419 stainless and so is the welding wire that I used, so it will probably outlast the muffler, but I'm not too concerned.

I do love the way these sound. I will say that around 2500 rpm it does resonate in the cabin and it is loud, but above 3K rpm's it quiets down and sounds good. Driving through my neighborhood I can set off car alarms with it :biggrin:

I used to set of alarms too. :)
I'd do it on purpose when I found an annoying alarm.

Do you recall the model number?
Does that one have a 3" tip?
Mine does. It's too ricey for my taste.
I'd like to find dual tips.

Steve, do you have a resonator on your exhaust? From the sounds of it your resonator could be bad?

I'd have to take a look. It's all rusted out. It's been on the car for probably more than 8 years.

Ok, I would think your resonator would be bad if you car sounds like a ricer at low RPMs

I would agree with this quote. My car does not sound anything like a ricer.

Here's a picture of the muffler from the summer.
It's worse now.

Steve, you may need to get a new exhaust, it looks like the original exhaust.

It's not the original, but yes I know. It needs to be replaced.

Steve, this is the label from the box the muffler that I used came out of. Hope this helps.

I just ordered one from Summit.
Looking at the description, Muffler, XL 3 Chamber, 3 in. Inlet/Dual 2.50 in. Outlet, Stainless Steel, Natural, Each
http://www.summitracing.com/parts/MPE-13288/
Did you install it backwards?

chrisbec 05-13-2010 03:20 AM

Sweet!

According to the muffler description it can be used either way (2-to-1 or 1-to-2). I suppose in the traditional sense as you may see it on a dual exhaust 4 cylinder Honda (splitting from 1-to-2) then yea it's backwards.:wink:

1996 328ti 05-13-2010 03:59 AM

OK, cool.
I'm going away so I should have it when I get back.
I brought the car to a shop today to be sure he would work on it.
Sure, no problem. Just pick up the exhaust and bring it in.

Only thing is I have a cat on the way out.

I thought my old Dynomax was loud because of the holes.

Does this thing quiet down over time?
