Looking for sidepipe sound from a muffler
Can't afford Borlas and Big Block :lol: All recommendations appreciated.
I know I am :beatdeadhorse:
Also, I have 2" pipes, not cats. Should I upgrade to 2.5"? And how much should I expect to pay for this?
Thanks.

With chambered pipes, is the routing still the same? I would love to see some pics plz. Also, pics of rear view of the car would be nice.
75Rag, mississauga is one hr. drive for me, 2 hrs in rush hour. I will have to pass this time, but once I decide what I am going with, I will ask for the shop's number.

Do you have to weld this system? or just clamps?
Does it include H or X pipe?

Question: I have headers on, what kind of work am I looking at? I was hoping for a simple bolt on.
Part numbers would really help me out. I will be calling MADVette today. Does Summit sell them? I like their service.

They are designed for the front pipes to bolt onto your stock exhaust manifolds. Your headers reach back quite a bit farther than the stock exhaust manifolds so you will either need to chop up the front pipes provided by MAD (I guess now they are called "MAM") , or fabricate something that will connect your headers to the rear pipes. Definitely not a "bolt-on" package as-is. Mike Allen might make a set for headers. This would include a shorter, different shaped front pipe that will connect the headers to the rear pipe. However, even with a set supposedly designed for headers don't expect them to bolt right up. There are so many different brands and sizes of headers you will likely need to massage the pipes to fit anyway.
The good news is, not having to deal with mufflers should make the entire system a lot easier to install than flowmasters. MJ

Thanks for all the responses guys. Much appreciated. :cheers:
Installing a Chambered Exhaust
Some "lessons I learned:"
1. Wear gloves. The aluminized coating on the new pipes will rub off on everything you touch, making a huge mess. It's far easier to slip gloves on and off rather than to wash your hands every time you need to touch something.
2. The sections are not marked. Even though there's only three sections for each side (plus tips), you'll be amazed at the Chinese jigsaw puzzle possibilities. Carefully align them on the ground next to your old system to ensure you get each part where it's supposed to be.
3. Use a file and smooth all the pipe edges. It'll make them slip inside each other and turn much easier during alignment.
4. The center exhaust hanger bracket on the back of the tranny is designed to hold 2" pipes. So you'll need to change/modify it just a bit to allow the 2 1/2" pipes to align through the holes in the frame. This modification is important, because you don't want the pipes to touch the frame, or they'll rattle. You can buy a bracket designed for 2 1/2" pipes (Corvette Central part 323078 for $39.00, 1-800-345-4122), or do what I did: Remove it (2 bolts), get a good cutting wheel and cut 1/4" off along the top of the bracket, and elongate (deepen) the bolt slots also 1/4". This will allow the bracket to mount 1/4" higher, and will align the new pipes to hang perfectly through the center of the frame holes.
5. Turn all the U pipe clamps sideways before tightening, instead of having the nuts on the bottom/straight down. You'll inevitably scrape bottom once and a while, and if the bolts/nuts are pointed straight down, they'll bend or gouge the threads. Turning the brackets sideways will give you another 1/2" ground clearance, and save your clamps.
6. The stock turn downs that come with the kit are a bit ugly. I found some cool 2 1/2" chrome flared turn downs at a local muffler shop (cheap too, about $10 ea.), and had them install them (see next item).
7. Even though you think you did a great job, after installing, take the car to your local muffler shop and let them tweak and adjust the pipes so they are perfectly aligned. It's amazing what the right tools and experience can do. I stood behind and under the car and "directed" (a little left, little more, back, .....) I then had them tack weld each joint, so the pipes will stay aligned. They also installed and tack welded the tips on for me. Do this right away, and it'll be easy for the shop to adjust the pipes (before any corrosion sets in). Only cost me 1/2 hour labor.
8. Lastly, use a stainless steel hose clamp on the turn downs, to mount to the rear hanger bracket, instead of the stock U clamp. You'll be amazed how much cleaner the pipes look without a huge U clamp hangin' visibly in the rear.
It's really quite easy, and well worth it! Enjoy.
