It sure looks like a tip in the pic's. Plus 2 on the coolant pipe welding. Also zip tie all rubber vacuum tubes.

Question for the experts, what other parts are you going to need when you do the coolant pipe mod, i mean you will certainly need some new coolant and the fittings but other than that, are there gaskets or other things you need to change because you have to remove stuff to get access to it? I would change the hoses that are prone to failure too at the same time but what else?

Hi Richard,
It's all by design - let me explain how our system works...The muffler internals are 2.5" on the 2.5 quiet. The muffler inlet/outlet connectors are 3" on all versions. The 2.5 tip has a 3" end to fit into the muffler, then quickly goes to 2.5" for the 90 degree bend and to the finished tip. This is by design, as it allows you to optionally use full 3" tips on a 2.5 muffler, which results in a one step louder exhaust system. We call it the 2.5 "sport" sound option. If the 2.5 is too quiet, you can liven it up with just a tip swap. Likewise on the full 3.0 system, if it's too loud, you can quiet it down with just a tip swap to the 2.5 tips on a 3.0 muffler. We call this the 3.0 "moderate" sound level. What we achieve with this design is 4 sound levels by swapping standard modular components and the customer has the option to vary their sound for special events, if they choose - for instance, if you like it loud and your wife doesn't, you can run the "sport" tip option all week, then put on the "quiet" tips when you are going for a drive with the wife. It's very quick and easy to do. Swapping mufflers is a little more involved, but still relatively easy and the same principal applies. The sound can be tailored to suit the situation. You shuld explain this to your mechanic - I think he will understand why after hearing this...

Hi Richard,
Yes, I am 100% certain that yours is a 2.5 "quiet" version. I boxed your system myself and verified this aspect prior to packaging.
And yes, it does immediately go to 2.5" once past the outside skin of the sides of the muffler. It is straight thru perforated pipe with an "X" at the middle and stainless steel wool packing in the can to absorb the sound. You can see right through the muffler, if you hold it up to light before it's installed - it's wide open with no baffles or restrictions...

Richard,
Below is a picture of the internal design - the picture demostates the design using a 3.0 model. The 2.5 is made the exact same way, except the pipe size is 2.5 throughout the internal portion of the muffler. The section after the "X" is perforated and the entire can is packed with stainless steel wool before being sealed. As you can see, it's straight thru - when looking through the muffler from the ends, you can clearly see a lot of light at the other end.

WITHIN the engine itself simply the above, Sportec upgraded internals, rods, valves etc, otherwise AMS Billet Turbos, AWE Intercoolers, Speedtech Exhaust, 3 Inch Y pipe etc, not much missing

Richard I have the same exhaust as you. If uncertain just remove the tips and look down the muffler, you will see the pipe steps down right away making the muffler internals 2.5 inches.
I had this exhaust sitting in my living room for about a week and I really studied and stared at it. Plus asked John a million questions
.
It's alot of fun, you'll enjoy it.

It depends on how much air the car is actually moving and the power level it is at & it is true that pipes must be coolant & engine must be kept clean so get it serviced soon in a few days.
