Is this car sterling grey? if so i think the car used to belong to the guy that owns Buscher racing. he had a few threads that were on modular ford about it. he built the stainless y-pipe back with a single muffler and i remember him putting a 2010 v-6 bumper insert on it as well. it has been about a year, but i think thats the car.
Two pipes into one..when they come from the factory with 2 outletsWhat makes you think it is a bottleneck?

The answer I was really looking for was a dyno comparison. Unless one has been done, no one can definitively say one way or another. To the best of my knowledge, this hasn't been done with this setup.
Buschur put it on the dyno.
"337whp and 304wtq with 93 octane fuel, after exhaust the car put down 354 and 314 ft lbs and did it three runs in a row, no cool down. After tune it went to 383whp."

Irregardless, I like the single exhaust idea quite a bit.![]()
