Just put them on backwards.

 

Or holesaw a hole near the outlet inside, and plumb the exhaust into the last few inches. Some of the old fake sidepipes I saw back in the 70's did that for a hookup.

 

Well as I said before, I am not so sure if I really have to go for the NOS or not. I did not decide yet because as you said they are the same engines when driving them in the street without NOS. As well most of the parts are the same. So paying 2K and not use them???? I can use 2K on a roll cage instead. But for the time being I left this option open until I place the order for the engine. Personally I do not know the difference between a 300HP, 500HP, 700HP and 1000HP car. So I can't tell the difference. I am just talking values here and you have to understand me. Fortunately, the only "HI" HP car I went in is my 85 Camaro with a stock 5L small block.

Now regarding the side pipes, I only like the style of them and yes my wife already brunet her right leg with it. In fact she does not like them at all!! Honestly is not ergonomic as it sticks out and may interfere when going in and out but for me looks nice. I need to look more into this.
Thank you

 

If I decide to have the side pipes, I need them to work and not just for appearance. The exhaust system I had on this 78 camaro was - from the headers to the mufflers (mounted approx underneath the driver seat) then 180 degrees bent to turn the pipe forward and then a 90 degrees bent to turn the pipe out to one of the 4 tubes of the side pipe assy. So I can use the same method if necessary.

What I am concerned is this -

1) I will do the frame connectors to tie the front and rear frame together. May this interfere when crossing with the 180 degrees or the 90 degrees bends?

2) Will there be a difference in performance or performance loss if the length of the pipes aft of the mufflers will be long? I mean the difference between an exhaust that end at the mufflers (near the rear axle) and an exhaust that ends at the tail pipes (the one I had on my 78 camaro)

Thanks

 

clacia, did i read that right that the fastest car you have ever been in was an 85 camaro with a stock 5.0L? If so that was a 215hp car depending on the stock configuration. You are going to have a riot with a 572.

 

For reference my bone stock Honda Civic would wipe the regularly floor with a 5L Camaro my buddy had. 400hp on the street is getting hairy when it opens up. 600 is about useless and 750 is dangerous. My 76 Nova had a built 355 and if I stepped on it in second gear it would step out the rear into oncoming traffic. That is 400hp. My Chevy II was closer to 500 and had 4.88 gears it almost killed me on the track and street. I saw God once! Careful!!!

 

Come on now, i think my 620HP is just getting into the game and the 770HP with spray is just about perfect...for now.

 

With subframe connectors the sidepipes will probably be out of the question. And yes, the bends and reduced size to the sidepipes will restrict the engine's HP.
Those are legitimate concerns, but as Damon mentioned, the lack of experience with high HP cars is an even bigger concern! There's not even a slight resemblance from your stock 5L Camaro, and what you're planning on building. This much HP wont just get scary, it will get scary so fast you can't get off the throttle quick enough to avoid some things! Be very careful, and it may still bite you!

 

My 76 was my first legit hot rod. 350 four speed car. The test drive consisted of going down the street with the owner and turning around. It was built but had a qJet with a bad acc. pump. So I got some wheel spin on my semi doughnut and then a bog and came through the gears. The owner was a family friend so a bit of abuse was OK. I got it home after almost a year of making payments. My best friend and I pull out and take it to the end of my street that is T shaped with 45 mph speeds both ways. It took no coaxing to get me to do my first clutch dump. Right as a car passes I was in the rpms and let it go. OH CHIT!!! I had never had a posi. I had never had a 3.73 rear gear and I had never had a V8. The backend swung out so fast I nearly clipped the car passing. We sat in the road giggling for a bit but I was scared stupid. I am a firm believer that a 12 sec street car is dangerous. I have seen 12 sec cars wipe out wheels on curbs during show off moves. Spit axles out of the rear. Like Val said, things happen fast! Sometimes letting off is worse than staying in it and knowing when to do so is important.

I'm older now and maybe that has something to do with it. Weird thing is all my friends cars are 10 sec cars now and those are ones that the ambulance leaves with the lights off. I havent lost any friends directly to race cars. But my dads friend and his son put a crate BB in an Impala convertible. Phil was always the enforcer. Large man tall and wide. He took nothing off anyone. He said on the maiden voyage he looked over at the speedo and it was passing 100 when his son grabbed the next gear and lost control. It barrel rolled sending both flying. The son was able to walk for help but Phil was paralyzed from the waist down and laying in the woods. He spent the rest of his life in a chair. Just thought I'd share that one. Inexperience broke the strongest man I ever knew.

 

Thank you guys for sharing some of your personal experience with me. And yes i need to be very careful when driving if I ever manage to finish this project. As well I will have my wife with me and need to be more responsible.

Really appreciate your feedback.
