Hi everyone, I just finished up my exhaust today on my 90 5 speed
I used a set of the high flow cats, a flowmaster 70 series big block muffler (two in one out), a set of cutouts, and all mandrel bent tubing to eliminate crimps
It is 2.25 all the way to the muffler and 3 all the way to a 90 degree dump right under my driver's side door
I used 6 45 degree bends a one 90 bend in 2.25 and two 90 3 inch bends
The drivers side downtube came out perfect with a single 90 bend into the cutout and cat
The passenger side downtube was two accurately cut 45 bends into the cutout and cat
Atfer that i ran two 45 bends to get the exhaust to the muffler
Then i ran a 90 out the back and put a 90 facing down to dump the exhaust out
Then I mig welded every pipe together with a home depot cheap special 110 volt machine, it actually came out really nice
It sounds really good this way, I have had a number of different setups (flowmaster kit, my own custom 2.25 to 3 to 2.25) and this one has a real unique sound - almost v8 sounding
I have a little bit of drone but not much, more than the flowmaster but less than when i had two 40 delta forces flowmasters on
Hopefully I can get a pic or video of the system up sometime this week
I have the full mag-powers setup and a 10% overdrive on and im getting like 15 pounds of boost with it, enough that im kicking my tires out through 3rd until i heat them up when trying to hear how the system sounds
