They end right under the rear seat. They dont kick up any more dust than people w/open headers and I have no issues w/fumes. Ok

I don't even have them on my new street car but hope to soon. I've always used turndowns at the rearend, but turn them mostly sideways, I've never had any complaints of kicking up dust but I'm pretty much always on concrete. 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual

No excessive dust and no excessive fumes in car. Btw, the cheapest place I've found them in 3" is O'Reillys or Autozone, about $7 each. Summit's price on them is nuts.

I'll weigh some 3" when I go to the shop today.

Thats allot of weight off the car. Its not like I drive that much on the road any way... Im gonna pull the rear tail pipes and check the weight... /Tom

If it is drag racing, 50LBS over and behind the rear axle might well aid the hole shot. Most tail pipes won't weigh 50LBS. A few might, but most won't. When you pull them, weigh them and let us know what they weighed and what impact it had on your performance. Master, again and still

Tempest mopar Joined: Nov 2013 Posts: 595 Nashville, Tennessee	Originally Posted By Cab_Burge How about removing the tail pipes and adding extensions from the muffs to make side pipes exit in front of the rear tires like the T/A Cahllengers and AAR Cudas have I had a set up like that on my BB Dart, short 2.5 O.D. pipe from the fenderwell headers to the early Corviar Turbo muffs and then around 20 inches of 2.5 tail pipes out of the muffs and bent out at 45 degrees to the rocker panels in front of the rear tires, that work well They where easy to remove at the track and they didn't weigh a bunch either That is exactly what my '65 has. Not the same muffs but same idea.
