Race only exhaust set up, would this work?
Race only exhaust set up, would this work? What if you just add 12-18" tubing and a bullet muffler off the header? No x pipe, h pipe or y pipe? I understand that you don't want to go open header because you could burn out the O2s.
This would be a track only setup - and the drive to the track I guess... I know it would be loud, but would I pick up significantly more hp than my current set up? Current set up is dynatech supermaxx and y pipe with Borla. Supposedly I'm losing 15-20 hp because of the 2.5" y pipe... And I'm only dynoing 410 rwhp which seems to support that. My only motivation to do this would be to pick up that hp for the track.
Whaddaya think?

this has been talked about many times. straight pipe off the header will make you lose power. an x-pipe, h-pipe and y-pipe will net you more power because you will take advantage of scavenging. scavenging increases exhaust velocity and increases power. going straight pipe off the headers will simply mean you can't take advantage of the scavenging effect. your best bet is to run an x-pipe or h-pipe off the headers and call it a day.
I ran Bullets with like 10" of pipe off the collectors then the bullets. IMO It sounded like ***!. really choppy at idle and it was just retarded loud I mean uncomfortable. I mean seriously I work for the railroad and I can stand listening to the whistles blow inside the cab on shitty power but this takes the cake. Its way to loud and sounds like ***. I'd just throw a y pipe on and a bullet off the ypipe thats what I did and it sounds great!

I had Edelbrock LTs with 3.5" collectors, Hooker 3.5-3" reducers, Flo-Pro Twister mufflers, then turndowns. Never saw a loss of horsepower compared to the duals I used to have with a X pipe. I ran 10.85 cam only. Here is a video clip of the car:

I am running bullets off of the headers and turndowns. Its loud but for just a race exhaust its not bad. You wont loose much down low if your car is built w/ a high stall or launch at a decent rpm.

Heah if it is anything to ya, I am running PaceSetter LT's, No Cats, X pipe, and Flow Master Bullets dumped before the axle. it's quiet enough to drive, and loud enough over 3k that you cannot talk on the cell phone or to the person next to you with yelling.
I love my set up....I dont have a cam or intake yet, but that is coming soon.....It's you car man....Do what ya want with it....

I run a bullet off of each collector, and at the track i run a piece of pipe off each collector.
I bet you i wouldn't gain a damn thing going to an xpipe. The added weight would slow me down actually.
I lost NO low end torque going to this setup. I actually stepped up to kooks 1 7/8 -2inch headers and the bullet exhaust system at the same time. I gained TONS of low end, it felt like a monster. The sound is great.. don't know what else to tell you guys. Some of you are too caught up in the hype to try something new that works. Most f-body racecars run the bullet setup and it works great for them. Works great for me, might work great for you.

Sux2bu is an example.

OK, so I'm running boarderline 11s - should be 11s next trip with good weather - and I run a reverse split cam which apparently needs the least restriction possible.
For race only, launching at 3,500+ rpms, will the bullet muffler off each collector gain or lose ET for me? I'm not opposed to the x-pipe, but I'd like to explore this option first.
