Hi guys! I'm thinking of changing the stock exhaust system to a MagnaFlow Street Series Cat-Back (part no. 16633, see pic below) but I really love the square stock ends. I know it might sound stupid to buy an expensive new exhaust system and cut it open the first thing I do, but I wonder if it's possible to cut away the ends and use the stock ones. I actually already have an extra pair of stock ends (see pic below). Has anyone done this? I think I saw it somewhere but can't find it. The MagnaFlow retailer said there might not be enough space behind the mufflers to weld on the stock ends but I don't see why that would be.

 

I wanted to keep my original tips when I had my Magna Flow installed. The guy at the shop said that the original pipes were smaller and he would have to make an adapter. This would restrict the flow and change the sound.
He also told me that with the adapters on, the tips would stick out further. After a while of owning it, you don't even notice it. One thing, if you have a roadster, the exhaust might bang into the underside braces. This can be solved by using a large tie-wrap around the exhaust hangers at the back of the car.

 

Here's a video showing how a shop deleted the stock muffler and made a 'Y' pipe to put the tips in the original location.
It is one of the few videos showing the entire exhaust system.
If the muffler delete is too loud for you, you can certainly put a single Magnaflow/Borla/Any round 'can' muffler in that straight pipe.
It would cost about 1/2 of what that Magnaflow system with round tips that you are thinking of cutting up.
