[k98dave]

I switch from 7/8 to 5/8 and like that a lot better Still sounds great around town but I like it more for long hiway runs.

Gotcha, thanks for the feedback! I know sound is all relative, so I'm going to remove them completely this weekend to see how it sounds.

Oh, there are some LT headers that allow us to keep the stock mid-pipe? Hm, did not know that.

Kooks offers a H pipe with side pipes for their long tude headers

American Racing Headers has some that are made to keep the stock side pipes. No issues and fit like it was made by the factory.

All sizes are in stock and ready for mailing.

Just want to remind potential buyers to purchase directly through the instructions on TMO. You'll save money and the transaction is much easier for me to process compared to ebay.

Just paypal'd an order to you. Can't wait to try them out on my new to me Boss!

They're still up. I just bought a new set recently. I think he has to re-list them occasionally:

Oh BTW, there's also a new kid on the block. Quality looks similar, and they also make something unique:

Factory Style Restrictor Plate With Easy Slide Out

Save time removing and installing the side pipe restrictor plate. Now just loosen enough relieve the tension, grab the tab with a set of pliers and rotate 180 degrees. When finished simply loosen and swivel back in place and re-tighten.

Ordered a .75 pair. I’ve been living under a rock and didn’t realize you sell these.

 

[VoodooBoss]

Received your order, thank you. Your order will go out Tuesday because of the Veteran’s Day holiday.

People keep ordering the plates so I keep making more.
