if i wanted to be quiet i'd buy myself a kia and i don't want to be quiet, i want my neighbors hear me a mile away
Well then I hope you get a ticket for loud exhaust. I certainly don't want to hear that crap from anyone's car...
My dad's Comet had 2' pipes and it rumbled the damn ground and windows in the house. You want to be loud, make some REAL power. Don't just stick way oversized pipes on a stock (or very close to) engine, I might have to laugh at you. Side pipes are a whole diffrent story.
i got 10.8cc domed pistons trw in my 428 motor i think it will have the a$$ to back it up!now if i can get it to fit!
Leave the 3" pipes to the guys in the dooley diesel pickups that need'em. A good 2" to 2 1/2' is all you need on a v8. You want the pipes to scavenge the exhaust from the engine, not merely let it meander out the back. The reason the diesels need the big pipes is airflow...they have to move massive amounts of air to make power. A realitively stock gas engine will acutally lose HP with too big an exhaust, and the sound levels will rise. Just goes to show the old addage, If more is better, than too much is just right,just ain't so.
YOu need daul 3inch pipes if producing over 500hp plus. For 500hp or less to about 400 you need 2.5 inch unrestricted as in mandrel bent if possible same for above. 3 inch compression style bending really is about 2.5inch in the bends. So is 3 inch pointless, for most but not everybody. Power adder cars such as turbo , super charger, or NOS need the extra exhaust size because there expelled gases is much hotter and they expand more as a result. YOu lose torque by going to bigger piping if you do not need it. Typically horsepwer will increase on the top side and your MPH will be higher at the end of the quarter mile. However your 60 ft times will be down as a result of the lost torque. Steep gears can band aid this for drag cars and high stall converters. However you typical street car will only make problems in performance by going to big.
Bottom line: Your exhaust system needs to be matched to the rest of the engine's components. Running big pipes just for the sake of being "loud" is lame...
No offense, but there's a reason they quit making Mavericks in the 70's. Does this follow the same logic? I think the 70's style sidepipes are very appropriate for the 70's style car. I would not put sidepipes on my 2000 supercharged Bonneville. Not appropriate. But for a 1974 Maverick, very appropriate. I recognize that most on this site hate sidepipes, but if you look at any cartoon drawing or T-shirt of a Maverick, it will likely have a blower and sidepipes. It was "politically correct" for the 70s. I am restoring a 1974 Ford Maverick, not a 2003 Ford Maverick. It will look like a 1974 when I am done.
agreed, my motor is no slouch so i figure i could get away with a slightly wild exhaust. I truely do need all the flow i've got (plus a bit) I've got 2 or 2 1/4 on a "nowhere near stock 302" I'll probably keep the regular duals, out of practical reasons. but i kinda like that look of sidepipes. and people tell me i was born to late and should have lived in the 70's. as to the noise issue, sometimes it's obnoxious i agree. Just a thought... maybe muffler AND sidepipes???? scooper77515 i as one misplaced soul agree 100% with your commentary on the era appropriate use of sidepipes and i'd like to second the opinion of engine appropiate exhaust setups
LOL, no offense but if you want your car to look like a cartoon or a t-shirt, go with the dice and the shag carpeting on the rear package tray too! To each his own, it's all good. The only cars I thought looked decent with side pipes are mid-sixties Corvettes and AC Cobras. I have a 393 pushing about 450 at the flywheel and I am running 2-1/2 mandrel all the way bak. That was expensive as hell but worth it.
