Supermaxx & PRT's
Surely, somebody out there has a set of Supermaxx long tube headers bolted up to a set of B&B PRT’s. If so, please, tell me how you like the sound (and performance) of your car.
I currently have a set of PRT’s and an x-pipe and like the sound of my car very much. However, in my never ending need for speed, I am seriously considering a set of Supemaxx long tube headers. My worry, however, is that the car will be too loud. Last thing I want is the sound of my '74 souped up (header) Vega. (I was in high school then it was all I could afford
.)
Did you have the PRT’s before you installed the Supermaxx headers? If so, how much louder is the car with the Supermax headers? A friend of mine has a set of long tube headers with a set of Corsa’s (I don't know if they are the sport or touring.) In my opinion, his car is too loud. But then, I don't care for the sound of Coursa's. (I know MANY other folks will disagree with my opnion on Corsa's, but that's how I feel.)
Any "real life" experiences will be appreciated. Thanks.

I had this exact exhaust system. The headers made the exhaust note sound much better. It gave it a lower but kind of hollow sound. If you have the PRT's then you know it is a mean, dirty, bubbly, beltching type of sound and that part did not change. I think it sounded great at all speeds except at 65 mph in 6th gear. With 3.42's I was right at 1500 rpm and there was drone which I do not like. Hope this helps.

my opinion
I traded my PRTs for a set of B&B route 66s. I have the supermaxx system with the route 66s, and I really like them a lot. Not too loud, the reason I traded the PRTs was that I thought they would be too loud with the supermaxx (or any other header system for that matter). My preference of course....

I also have the exact same set-up. The 1500 rpm droon is terrible before and after the header install. At WOT sounds awsome. I did have custom off road pipes made to replace the cats. Not much change in sound, but the overall performance improvement was noticable with the headers. My car is a 2003, I have the new released headers. There was talk of the left side rubbing the steering shaft on hard cornering. I do not have that problem and have plenty of clearance. There may be an eaven newer version, but not that I'm aware of. Since you already have the x-pipe you may want to buy the long tubes only. Not to try and sell you on something but I may be removing my offroads and returning back to cats for emission requirements when I send the car to LPE. I have them listed on the forum. If you buy the headers only you will need a transition to your x-pipe. The supermaxx has a bell mouth ball/socket collector set-up with a 4 bolt flange ring.
Hope that helps.

Being loud is subjective 
………..our 00’ coupe had the PRT’s 1st.
Then we installed the FLPs, these headers are both similar. Made the PRTs less raspy IMHEO.
But it wins the loud contest in our local tunnels just about every time and runs folks out of the dyno room.
As you can see its pretty much a straight through design......
This set-up is louder than my 97' stroker set-up and I like open headers so I don't mind vibrations at 1500 rpms.
I suggest you try to hook up with someone who has them 1st and take a ride. Thats what i did for some folks years ago when they were deciding................good luck

Also the new Dynatechs have a much improved cat.

I'll tell you what I saw, though. They took a cat that is shaped like a cone on the end. That's normal. But then they shoved a pipe in the end and welded it. If the pipe ended right at the end of the cone, that would be fine. But that's not what they did. The pipe was shoved in past the cone so that the exhaust was forced to pass through only the center of the substrate. It's even worse at the exiting end of the cat. Instead of having a cone shaped transition for the gasses to pass through, they are forced to enter the end of a 2 1/2" pipe that sticks out into the breeze!!
Andy, I have a friend that just took delivery of a brand new set of Dynatechs for his Corvette. They are not yet installed. After reading your post, we opened the box and took a look at the cats. They are not at all like you describe. The ones you looked at must have been a very early edition. His cats have cone transitions on both ends. Those transitions smoothly open up, on the inside of the cones, to the full catalytic material on both ends. There is no straight pipe inside the cone on either end. Just wanted to let you know and clear this point up. The cats look very professionally done. In fact, the entire setup is pretty impressive to look at.
Ed
Your point about improved cats on the newer Dynatechs is well taken. As I mentioned, we thought the entire system was very well done and impressive to look at. He is very anxious to get them installed in the spring. I may well be picking up a set myself after winter!
