Larry's right. They are a totally different sound and it's up to preferrence.
My 180's are a pain to work around but I enjoy the look and sound.
You won't see a performance difference over mind-train exhaust.
Here is a taste of the sound of 180's compared to conventional headers. The 180's car passes at 2:13. Turn up the volume

Ansa mufflers, btw, cost me 35rwhp on my previous stroked cat.

Also, the sound varies largely between exiting straight out the back or out the sides.

Sweet music from the 8-cylinder Cleveland symphony playing through those 180 horns!

The sound of that yellow car with the 180's is what I really would love to have! Any 180's for sale out there?

THe biggest single problem with 180s for me is, I love the sound so much that in competition, I always stayed in the throttle a little too long, making getting thru the next turn difficult. And the radiated heat off all those pipes will boil or burn the paint on any panel within about 6". So you need a heat shield.

180s at speed or at WOT is a symphony for sure. The 180s sound relatively quite at idle, kinda boring which I like. It allows you to cruise around town without worry of the sound police. The idle actually sounds a little more cammy with the tips pointing towards the ground (when they exit through the original exhaust opennings.

Mindtrain actually sells a crossover tube to balance out the pulses of their exhaust. It makes the idle quieter like the 180s and still have the wild CANAM sound at WOT with the added benefit of balancing the exhaust.

Good luck again on your quest. I am sure you will enjoy whatever you end up with.

Question…… when switching to 180 headers….What have you guys done with the area where the mufflers used to exit, besides the obvious (welding / body work / paint). Any pictures / any ideas. Does it look OK with the areas empty? Any pics with the muff area empty...

I have many miles on mine without heat damage. They are ceramic coated witout any shield

Not much you can do other than filling with new metal. It's on the "to do" list....
