Fentons: Flowmasters: Never have liked Flowmasters. They sound like a boat motor that exhausts under the water. Smithys or Cherry Bombs with full length pipes are much better, IMO.
Fentons & Flowmasters Fentons reduce available power on daily drivers , they're a racing header and so don't provide good midrange exhaust scavanging . If you just want noise and lots of it , use them but be ready to be left behind by the true Stovebolt enthusiasts who'll have more power on tap . Flowmasters are a tuned muffler that require more flow than an InLine 6 can provide , yes they'll uncork your exhaust system , no they won't sound good like they do on any V-8 ~ the pleasant Basso-Profundo rumble of the 350 SBC will be transformed into a nasty buzzing / blatting sound that'll piss off everyone for two blocks , even my son the racer didn't like his Flowmasters on any thing but his V-8's and yes , he tried , took 'em off again . If you like the rapping sound , take the time to find some really long glasspacks , Smitty's for example , over 29" long , you'll like that . L6 engines require careful exhaust setp and muffler selection to sound good . Or , you can simply run one single open pipe and they'll sound very nice if a bit loud at Highway speed .
Or you could put a set of custom made 1 off Stainless steel Fender well headers on....Woooo Hoooo....Big Tim
The Fenton headers are the gold standard of improved flow of exhaust gasses from the motor & they improve horsepower across the board by 10% + . If you want a loud raspy rapping sound use 1" or 1 1/2" exhaust straight pipes with no mufflers. If you want a mid range sound use 2" pipe with Cherry Bombs. If you want a smooth tone.... use 2" pipe with glass packs.
Just Sayin', I've got a brand new, never been installed set of Fenton's for a 235. Kain't Give'm away but I'll make them a good deal. Very close to Kingsport TN...in Greeneville TN. Flashlight
I'm more along these lines.... http://www.youtube.com/watch?v=Uu9fJWFpmuE&feature=related Flowmasters work great on v8s, but they get a resonance at certain rpms. I run flowmasters on mine. I may be switching to Ultraflows after installing them on the 62 F**D I just did.
