OK Guys, Here is where it hits the road. Who has had the fine priveledge of being able to do a high speed auto-X in a high performance car with open pipes???? OPEN window -let it rip!!! 9000rpm in an old 911, straight pipes, no air cleaners, big venturis, Inside racing tire 6 inches off the ground, trying to save my ass from terminal oversteer!!!!! YEEHAWWWW mf. On a more serious note, what is the minimum muffler one can ease by with on the street??? I am seriously considering having flanges welded on my flowmaster tail pipes so that i can get rid of the resonator tips that make it streetable - for the few times i am able to get the 308 to the track. OK guys, how far can you push it????? With some humility and pernicious impecunity, I remain, chris
About 2 years ago when I frequented this site often, I posted a thread on a flowmaster that I modified for my Euro 308 gtbi. I took the cross flow model Flowmaster reduced the inlet and outlets, mandrell bent the exhaust tubes and added a set of dual outlet resonators. Also wrinkle black finished the exterior and ground all the welds smooth. I designed the unit to be a bolt on item so I included all the flanges and mounts for a Euro 308. I am very impressed with the sound and performance. And so were a couple of members at the time when posted from numerous emails to build more. I purchased several ready made systems, but they made the car sound like a mosquito. The sound is a deep rumble and has the unique Ferrari whine in acceleration this was a great wake up call for the overall performance. It took aprox 8 labor hours to complete with much modification to reduce the 2.5 inlet and outlets to the smaller Ferrari diameter, plus the tubes had to be mandrell bent to afford a tighter equal bend between the frame rails. I will try to look back at some old pics to see if I have any to post.
Depends on the RPM you drive at as you pass Officer Stadanko. Neutral works well Seriously, try for about 95dB or so at 50 feet. Keep rpm down in the city. "How fast can you afford to go" is a nice universal answer
Flowmaster exhausts are designed for domestic vehicles... ...Not high-revving Italian sports cars. I think it spells disaster.
