I've been running the Tony Branda tri-y's for twenty years now. I had them coated after fitting and they still look OK with over 16,000 miles. A local shop made the h-pipe and I used 28" long 2 1/2" Thrush glass packs and side exhaust. The mufflers only last about 6-7 years, as I'm getting ready to install my third set of mufflers. This makes a good exhaust system for someone that intends to drive their car. If running a Lakewood blow-proof bellhousing, must trim the the block plate and bellhousing flanges for header clearance as well as for the lower clutch rod. Make a HD lower adjustable clutch rod out of 1/2" diameter steel and temper the tip, as the clutch pivot location is slightly different than stock and will exert more force on the lower rod. Stock rod will bend especially if using a HD clutch and pressure plate. There is no interference with the tri-y's to the quick steer idler or Pitman arm.
