My new exhaust!

Man, this thing finally sounds like a truck! It's loud enough to where I can no longer hear the exhaust manifold cracks and it definitely gets looks, but I don't think it's quite loud enough to annoy Johnny Q Law unless I really rev the hell out of it right in front of him. I "hi-flow modded" my first cat and cut off the 2nd one, and stick welded (really ****tily) a $5.50 3" extension pipe and then a $4.60 3" turn-down on the end of the first cat, both pieces from AutoZone. I now have several inches of clearance to both the tranny and tranny crossmember, where previously the 2nd cat was riding the xmember and the bent part of the pipe was about 1/4" from the tranny, which ain't good! Wow, I was amazed at the sound and sound level... absolutely perfect [img]images/graemlins/cool.gif[/img] High rev power is way up, still not a race truck thanks to the mushy E4OD shifts, though [img]images/graemlins/frown.gif[/img]I don't know if it'd do it justice, but I'll try to get a sound byte for you sometime this week. Best damn $12 I've ever spent [img]images/graemlins/burnout.gif[/img]

Re: My new exhaust!

That must be the shortest Bronco exhaust I've ever seen

Good going on the price, hope the emissions boys don't catch up with you. Must sound great !

I just took my last emisssions test ever today, I'm now officially exempt forever more.

I'm off to order the Summit shorty smog headers with the money I saved being tested this month instead of next month.

Can you believe those slimes ? They're jacking up the money needing to be spent from $200 to $450 every two years. If it did anything I'd be glad to comply, but it's just one big cash grab !

Swine !

Good going Muddy !

Re: My new exhaust!

So it's gonna cost $225 per year just to get inspected? That's crap... definitely glad we don't have any of that here any longer. Yep, it's damned short but doesn't seem to put fumes in the cab, at least not any worse than the cracked manifold does. On that note... since nobody has much to say about my setup I'll hijack this thread and ask:

If I don't care about the EGR tube, can I pull a manifold off any 351 engine back to its introduction? Did they change at all when the EFI showed up, besides getting the EGR port? I've found all kinds of EFI 5.0's at the U-pull-It yard but EFI 5.8's are just not around, but I'm sure I could find a carbed one somewhere if its manifold would work on my engine.

Re: My new exhaust!

I can't believe you don't get a ton of fumes! I had mine exit throught the hole in frame by a body mount and befor rear tire, but the wonderful PA law says that only TRUCKS with Truck Plates can exit before rear axle!!!BS [img]images/graemlins/bs.gif[/img] [img]images/graemlins/AR15firing.gif[/img] So I had to go further back. Well at least you took some heat away from the tranny. That is worth the 12 bucks anytime!- [img]images/graemlins/beach.gif[/img]-BOB

Re: My new exhaust!

I'm going to strait pipe mine past the tranny and then cover the pipe with header wrap. I want to do it to the pipe all the way from the collectors past the radiator.

Re: My new exhaust!

As soon as possible I will thrown on pictures of the exhaust I have on my 88 302, I think it might just beat ya on shortness buddy, It pops out right in fron of the door on each side, completely straight piped, and four inch pipes running the lot.Although I do have to say I might have to try your method once I drop in this Thunderbird 460 I have sitting in my garage. Don't forget, treehuggers blow [img]images/graemlins/scs.gif[/img] [img]images/graemlins/40BEER.gif[/img]

Re: My new exhaust!

slicker, I'm rollin around with the windows down right now, so for all I know the cab will become a box of fumes with the windows up. I would not consider this an ideal exhaust by any means... in fact, I wanted to run a pipe all the way back behind the tire but AutoZone didn't have enough pipe to allow me to get the exhaust back past the tranny xmember so that an exhaust shop could get to it, and I bet it gets really expensive if the shop has to unbolt the y-pipe to do any work on it. If I can find more 3" pipe nearby, or online cheap, I'm going to extend it at least back to the front of the tire, if not the back of it. Unless you're looking for crazy loudness, there is no advantage to having such a short exhaust because you'll actually get better gas scavenging with a longer pipe, which theoretically helps performance. This is supposed to be a temporary exhaust, but then again my front bumper was "temporarily" off for 2 years [img]images/graemlins/smirk.gif[/img]

For that guy in the peanut gallery that doesn't like straight pipes, send me a flowmaster free of charge and I'll be glad to weld it on [img]images/graemlins/grin.gif[/img]

Re: My new exhaust!

Muddy,

Stop by any exaust shop and tell them what you want, ie give me a 36 inch piece of 2 1/4 pipe with a turn down cut in it, and they will. You can then go home and weld it in.

I tore off my tail pipe where it exited the right side so I stopped by and they measured bent it for me for about $15. Quick easy money for him.....
