Are there any good off the shelf larger then stock exhaust systems for the first Gens or will i have to have something built for it? Like 4" or something like that.

 

I am using a Stan's Headers 4" turbo back with a Donaldson straight through muffler. It uses all the stock hangers except for the tailpipe. A bracket is included with the kit that you weld where ever it is called for. I was told the reason for this is because of so many different variations in tailpipe bracket locations even with trucks of the same year. Rip Rook makes a nice exhaust also. However, the standard would be a 3" DP with 4" back. You can order it with a 4" DP but you will need to finish fabricating it; he is not jigged for a 4" DP. It doesn't include hangers either. My system was very easy to install. The most time consuming part was cutting off the old exhaust. It was rusted and wouldn't come apart at the joints. You AND your truck will be happier with an exhaust upgrade.

Thanks for the Info guys, looks like the Stans Headers system will be the one i will go for.

 

Where can I find prices and info on the stans headers 4" turbo back? Looking to buy prettier, thanks

 

Will a 4 inch downpipe work with a wastegated housing, auto tranny, and transfercase on my 89 or would I need a ballpeen adjustment here and there?

 

This kit fits like a glove on my '93.

Possibly an 8oz adjustment...but you won't need a 16 oz one.

Has anybody found a kit that has dual tail pipes? I kinda like sharing the smoke and sound with both sides of the street.

I feel for you 1st geners when it comes to the exhaust on a 4x4... WOW.. is it ever tight around the transfer case... 4in is very tight... anyone done something with 5in... looks like the only way is out the hood.. lol.. or all the way below the frame....

 

Duals are for gassers ...

 

There are a couple company's making a 4" mandrel bent piece to go around the t-case. Works good. Prior to buying this, I tried to build a 5" downpipe back setup. 5" *fits*. Just its gonna take some time and welding to get your angles right so that nothing rubs. BTW, I stuck 2' piece of 5" flex through there. It fits, just you'll have to get it just right because there is little to no clearance between the frame, t-case, and front driveshaft. It has been done though.

 

Hmmm, this coming from a guy that put TWO stacks on his truck!

Stacks are different... although if I do it again, it will be one stack.
