Default True Duals Mufflers Dumped Off Headers Or Y Pipe With Bullet

What is the best exhaust set up for racing. Headers with bullets off of them w/turn downs or Do a Y-pipe off your headers and fix one 3 inch bullet off of that. Any pros or cons please give me your 2 cents.

I bought two bullets to put off the headers but the one on the drivers side wouldn't fit with the floor the way it is, its gonna have to have some pipe added onto it, with a slight kick in it.

turndowns off the collectors if you have no noise standards to go by. I ran my car that way last year with very good luck, this year I had a 3.5 inch pipe run off the collector to a 44 series flowmaster, and a lenth of pipe off the back of the muffler to dump in front of the tire for a noise rule I have to meet for englishtown, I've run it with that and with the headers open and have had good luck both ways, with 2 3.5 inch pipes there's really not enough of a restriction to matter I don't think, and it's quiet enough so etown didn't care.

But, if you have no noise/muffler rule, I wouldn't run any more then you have to.

The Edelbrock STD mufflers sound good, flow good and are one of the thinest we could find for ground clearence.

How thick are the case on those? The super 44's I went with have a 4 inch case, and inlet/outlet are tapered up to the case diameter, so what we did was cut them off where it was 3.5 inches in diameter, and welded the 3.5 inch pipe onto that.

Dual 3.5 inch exhaust... if that's not enough I don't know what to say.

The 3" were like 3 1/4" and the 3 1/2 were 3 5/8" .... so pretty much same size as the tube.

3 1/2 will work for a bunch of power for sure!

Wow those are really thin. That's cool.

Yeah, when I got the 1 7/8 stepped to 2 inch headers with the 3.5 collectors, I didn't want to go adding any additional restriction to the system. I didn't bother with an h or x pipe as I personally think that they're nothing more then a gimmick, just 2 sections that I can unbolt off/on the car in about 15 min, no clamps on the exhaust either, it just slides up onto the collector of the header and has one 3/16 bolt that goes thru a tab on the collector we welded on, and one on the exhaust itself, and I pull one bolt out of the d.s. loop, and bolt up by the hangar we welded onto the muffler.

Simple, easy, and after painting it flat black, almost invisable
