83 H-pipe or X-pipe

[speedfreak460]

Hello there, I was hoping for some help on what i should do with my exhaust. I got a 83 with a few mods and hooker pro comp long tube headers. Now at the collectors instead of the normal 2 bolt connection flanges its got the three bolt. I want to run dumps befor the axle but i need the h or x pipe first just wanted to know what would work i know ill prolly have to hack my brand new pipes up a bit. Oh well As long as i get them On there and fitting well.

Thanks dan.

delete the x or h pipe and run the exhaust all the way out with nice tailpipes. It will be easier and sound a lot nicer. The x or h quiets the exhaust too much for me. I welded my crossover pipe shut on my mustangs exhaust with a piece of round sheetmetal so its undetectable. The exhaust sound is much more powerfull, like a v8 engine is supposed to sound like. My first car a 70 chevelle, 450 hp, long tubes, 550 lift cam, sounded so awesome i would never have killed that wonderfull sounding machine with x's or h's. The x or h pipe is nothing but a gimmick to quiet noise pollution and everybody fell for it. lol.

H = slightly more torque, deeper rumbly sound
X = slightly more top end, rippy/raspy sound
Straight Pipes = belong on hillbilly trucks

You may have improved the sound to your liking, but it cost you some horsepower and torque along the way.

A crossover section in your mid pipe is no "gimmick", it aids in equalizing the exhaust pulse and drawing spent exhaust gases through the system.

Rule of thumb...the larger the cross over section, the better the performance and louder the exhaust note. The smaller the cross over section, the more the exhaust note is quieted, but the equalization effect is reduced.

To each their own though.

First off thanks I'm going to probably run the pacesetter off road x pipe and hack them and put my existing flanages on the hpipe and then run some sorta muffler with dumps befor the axle

why does everyone go with dumps? I hated my car when I had dumps. I ran mine all the way out and love it now because of the lack of interior vibration and resonance.

I had dumps on my '84 GT. At first I loved the sound. There were, however, times when it gathered too much attention. Everyone always looked my way when I was trying to sneak into a parking lot. Kind of like a Harley with straight pipes. They sound good but if you want the attention of EVERYONE within 100 yards, you'll get it-whether it be John Q. Public or Johnny Law-with ticketbook in his hand. My 93 LX is going to have a full system with tailpipes. I recently saw/heard a '91 LX 5.0 with an American Thunder system with no cats and it was PLENTY loud...but sounded REALLY good. Like an american V8-powered machine OUGHT to sound.

You can get a X-pipe kit from summit, you would need to weld on the 3 bolt flanges however... Their X pipe kits start at $99

Straight Pipes

The only thing that can get respect with straight pipes is if they're tuned length collectors at the end of long tube headers...but that's a whole different story.

Killing the crossover = killing exhaust scavenging.
