Exhaust upgrade

[texasjeeper]

I have an 89YJ 6 cyl and I am going to upgrade my exhaust. I have already done quite a few mods (3100 carb, electric fan, K&N filter) I am needing advice on what works best for durability and performance. I want to go from the manifold back. I also am about to do the HEI upgrade on my distributor.

Cant go wrong with Banks. I have everything but the header, love it.

While you're at it, route the downpipe in front of the oilpan sump (TJ design)instead of beneath the bellhousing (YJ Design).

I cannot find a Banks exhaust application for my Jeep, All they have is '91 and up. So I am guessing Banks is out for me. Really all I need is a good exhaust manifold, muffler and cat. I can reroute and customize the piping (Friend has a pipe bender and welder). Any other suggestions?

Banks makes universal muffler's and cat's.

I like my flowmaster for a muffler. Get a highflow cat and any header besides the factory one and you'll be set.

I think I am going to go with a Borla header, any highflow cat, and a flowmaster muffler. Thanks for the input guys.

Great choice. I think you'll be very happy with the performance and sound.
