I agree....but the large backhoe that crushes the "peoples curse" award sure can......and an extra 100hp DESTROYING the other crapboxes sure will get even more attention.... the 2900lbs 200whp volvo is one of the most powerful cars out there.....we will be lighter with only 10whp less, but more torque....so it will be interesting....

Those are the stock single cat pipes = too small. That Y is horrible too.
Move up to something like I made from a 32V cat, along with the grinding, and it will make a lot more torque and hp. If you don't use 32V pipes, don't go larger than 2-1/4" OD, or it will lose power. Also, don't go directly into a Y - keeping the sides separated for a bit is better.

How much of a HP gain do you think we can get changing to a better crossover pipe?

With my '81 auto 4.5L, switching to that HY-pipe, plus the exhaust manifold grinding, with basically the same catback as you have, I gained >20hp and >50tq rw sae. (190/222 -> 214/277)
The 4.7 might do even better. (More displacement, higher compression.)

If you are pressed for time or money, I reckon you can borrow this pipe for as long as you are racing that car, as long as you bolt it on. IE. you'll need to weld the 4 bolt connector back onto the cat-back (you'll need the doughnut, too). I took it off when I sold my '81.
Just pay for shipping.
To get the most out of it though, you do have to grind the outlet of the manifolds 1-2mm to match the 32V gasket.

hey this car makes plenty of power for now, im not going to rebuild the system for another 5 hp, the parts i had are what came with the car, they work fine. if im going to build a sweet exhaust system for this lemon it will be a fine twin turbo set up with stainless pipes.
but if your willing to lend your pipe ill bolt it on, i am intrested to see what our dyno says it will do

As much as an extra 22 whp would be nice.....I think we'll wait until after the 1st race....then we'll have more time to play with it...

yeah brian we can wait at least untill after the trackday to see if those hours of labor to gain a few more ponies will be worth it.
the front bumper has been gutted a bit, plasma cut holes in it, ends are chopped off and removed the shocks for solid weld in mounts, cut about 25-30lbs out and it will still provide sufficient protection in a moderate front impact. we will keep all of the rear. this car is going to have amazing stopping power and be surrounded by inexperienced drivers that dont know how fast we can stop. we want all the protection possible for the fuel tank.
the intermediate muffler probably doesnt do much to dampen the noise but i think we may be borderline as it is. we really should invest in a db meter

the fuel tank is a collapsible plastic, like the cup cars use and is protected by the rear frame the bumper doesnt do much and anderson can attest for the effectiveness of just the rear plastic bumper in spreading the load and it pops right back out.
front and rear bumpers will take 50lbs out of the car.
You have to drive the car around and out of trouble. thats the trick.
Its not going to be that amazing on stopping power, but it will be effective with the power enough, to get out of trouble and reduce chances for conflict.

we got alot of work done today, thanks for the hard work brian!
Brian got to drive it for the first time today! with no seat too, he looks like a teenager that just stole a sweet hot rod. lol
brakes bled, car lowered, new tires on, more weight removed! we are down to 2575! so next is the cage and working on transforming the rear into something unique.
