Exhaust question

This is to build of the previous Header question. What type of exhaust systems is everyonre using? I've seen a lot of "bolt in" systems. The one in particular is Dynomax. Is it any good? They make one for my 1978 GMC Jimmy.

Re: Exhaust question

<font face="Times New Roman">
<font color=green>I run Heddman headers, 1.5" primaries, 3" collectors to a fulll dual system with 2.25" pipe and 3 chamber flowmasters. The pipes dump in front of the rear wheels. It cost about $150 for the headers, $100 for the mufflers and I think about $100 to have an exhaust shop put it all together with mandrel bends, except for the headers which I put on (and drove to the shop with just them[img]images/icons/cool.gif[/img]).

Re: Exhaust question

I've got Hooker headers and Hooker header-back pipe kit. It all fits good and is no brainer. It dumps behind the tires out the sides.

The pipes are a bit short for a longbox standard cab though. I couldn't use the mufflers I bought because they were too short. It needed to have two more clamps and two more hangers as well.

Re: Exhaust question

I've got Flowtech headers and Flowtech Afterburner mufflers. 2.5" duals from the headers back. Turn down at the rear axle.

Re: Exhaust question

I've got the Hedmans from Summit, Hooker dual exhaust kit from Summit (2 1/4 pipes, exits out the sides behind the tires) and Summit mufflers, all together I spent about $240. My only complaint is that the Summit mufflers are quieter than I thought they would be.

Re: Exhaust question

Is it worth the trouble running headers? I need a new exhaust system And I thought I might as well go headers and duals.
