Mufflers

I will soon be ready to install my new exhaust on my LSC but I have a question.

I will be using the stock Gen II tips and Borla ProXS mufflers. I don't really want the mufflers showing like most people install them. I like the way the stock ones don't really show.

So do I need the inlet/outlet: offset/offset, centered/offset, or centered/centered?

I'm using these exhaust kits which I'll have the exhaust shop modify as needed.



This is a photo from the eBay auction:

Which is NOT what I'm looking for. I'm thinking centered/offset with the muffler mounted vertically with the offset outlet toward the bottom and the muffler tucked up in the stock location.

Some photos of Gen II's exhaust setup would be greatly appreciated.

Sorry for such a long post...

Get the offset-in / offset-out that way they can be turned up under the car.

I have the offset-in / center-out configuration on mine. You won't be able to do what you want to do with the offset-in / center-out.

I would think center in/offset out would be the easiest to hide. With offset in and out you would have to bring the in pipe up pretty high to meet up with the muffler, but with center in it would be easier to get the pipe to the inlet, and the have the offset outlet at the bottom with the muffler turned so that it is hidden up in the factory location.

center in/offset out is not how the muffler is made or designed to operate. That would be installing it backwards.

They may be reversible but I don't think so.

Here's the Borla page showing the different configurations.

Dang it, you're right. The don't offer a center inlet, offset outlet...

I'll have to give them a call and ask if they are reversible (which I kind of doubt).

Wonder what would happen if you went center inlet, dual outlet and plugged one of the outlets? (Although the 19ā€ case length worries meā€¦)

Actually what I need is an offset inlet and an offset outlet, where the inlet and outlet are offset to the same side.

If I were you I'd get the offset-in / offset-out, turn it on it's side and call it a day.

That EBAY kit looks nice. Good mandrels around the gas tank and differential. I wish i could send a good pic of the custom job I did but I can't. We spent a lot of time welding up the 3" mandrel bent tubes to do what that kit already has.

So I'll get the offset inlet/centered outlet and reverse it. I think that will work perfect.

And get this: I emailed them today at 10:53 am and received a reply at 11:18 am!!!
