Gen 5 Camaro External Bolt-On Tech - Dumped mufflers at rear, wow!

So after I got my cam and tune done, numbers not what I was hopping. Tuner said my home made exhaust was killing me. So I decided to try something, I cut the back section off, put my 1 chambers at the reared! It's not the best looking setup, they just don't belong there. BUT... WOW, I am not kidding it's a hole new car! I was pitting out 432hp 424tq and he said I should be around 450.... Well I bet it is now! I can't believe how much faster the car is, it picked up power everywhere, low end and top end! The sound is crazy freaking loud when I punch it now but still decent at a cruise.

That sounds nice..any pic?

Dumps are good. Saves a lot of weight, too. I've got classic chambered 26" chambered pipes after the X and dumped right at the pumpkin.

Factory mufflers are a restriction after bolt-ons and cam? Any research on this?

Its just common sense. The stock mufflers have baffles and packing to dampen the noise, that stuff restricts the flow. The exhaust itself is very good, 2.5 inch duals all the way back with an H-pipe. From what I understand people are picking up the same power with an axle back kit(mufflers with enough pipe to connect to the stock system) as they are with a full after market catback exhaust. I think it would only be necessary to upgrade to headers and highflow cats to see large gains and an upgrade to larger diameter piping would probably only be needed with FI or stroker applications.

It might make sense and I agree but these cars have been around a while and I have not seen any track or dyno proof.

There's tons of research on this fact.....including minimal gains with cut outs.

If the OP gained 20 RWHP from this mod I'll blow him in front of god & country.

By the way...I saw the car run 12.9 @ 114 yesterday.

Your trap is right in line with your tuners dyno #s.

PS = I made 470 rwhp in my cammed 10' SS with Kooks LTs & hi flow cats and a SLP LMII Axle back.

My car ran 12.8@113.3 on saturday. I had 3 runs with a 1 bog, 1 spin and a 1 wheel hop. Could not drive........but beat a 5.0 on the first 2 runs so I feel better.

I wish I coulda met up with your guys at GLD yesterday.

I'm planning to go tomorrow night m'self.

I'm ready to cut off the stock mufflers and I've got 3" bullets to put in their place. Should sound good and drop some weight

I'll be doing the same only with bullets dumped at the axle.

I already pm'ed mpd-1 on C5 and they will fab me up a smooth rear valance with no exhaust outlets so it doesnt look so goofy without tips.

Ill take a vid soon guys, I blocked my holes with plexy glass... turned out great and sounds awesome!

Ya I was having traction problem all day first time with the cam, and also ran 3 12.7s with a best of 12.72 and 114.7-9 MPH on a 2.2-3 60ft.... Ill line up with your vette any day of week bud. Ill have 12.3s @ 115-116 on street tires before the end of the year!

:corn: Were havin' fun now!

OMG, this comming from the guy that couldnt even drive his own car for the life of him! Broke his shit and sold his camaro because it was it was total fail... kiss my ass dude, first off I dont have cash to bet or blow with a kid on the way... never called you out... you started this shit, and I dont even need to sort my junk out because I already have you beat. I seen your driving and was nothing impressive, dont worry you will get the call next time I head out. Now you can get the credit card out like a bitch and make sure you buy up some parts because they way it sits you better bring more then a 12.8!

It's getting deep in here. Mabey we need a 5th Gen Shit taking section added to the board.

The fun is just starting.....wait. :burn:

Hmmmm, I couldn't drive my own car huh? First off, wash the salt out of your vagina. Secondly, stop sucking Chicago 5th Gens dicks and learn the facts. I let Dan drive the car the first few passes, and the shitbox broke. Before I could get to the track, the motor blew. I'm pretty sure I can drive hoss....bring your money.

You already have me beat? Fuck, I hope so....you've got a cammed LS3 vs a 98 LS1 with a set of headers and a tune. What did you run? 12.7? I ran 12.8....YOU'RE AWESOME! Let me slap a cam in my Vette and we'll go mod for mod. Just let me know when you're ready.....I won't take your money if you can't afford it, I'll settle for taking your pride.

:jest:

I have been told by a few people you cant drive for shit, looks to be true. And I would say were pretty even, my cammed LS3 on stock tires and your on DR's pretty much even things out the track... Like I said, Ill let you know next time I go, I want to see this big talk in action. Had to buy vette cuz you couldnt cut it and gave up! 470 at the wheels and never an 11 sec pass, thats pretty fucking sad... shows how good you! Dan had to drive your shit just so you post a decent time :zzz: Dan got a black vette and so did you... sounds like you should get off his nuts and be your own man.

O ya... 12.7 is faster then 12.8!

Hey homo, take T-Bones cock out of your mouth and pay attention.

First off, Dan made a few passes in the car and BROKE it before I could drive it that day. The next week the engine blew so I NEVER got to make a pass in it with all the suspension work and drag radials on it. I'm pretty sure I know how to drive.

Second, you're right, I did give up because making 470 tire for an 11 second pass is weak as fuck.

Lastly, I had my black Vette first....If you're going to talk shit, get the facts straight.

See you at the track, make sure you have your good tires, because I don't want any moaning or bullshit excuses from you.

What ...not having fun anymore! I wont have tires till next year sorry... I dont think I am gonna need them anyway.

Maybe you guys should throw down in fisticuffs afterwards lol

Who do you think would win that one ?

Anyways...do you know he has a very small cam that uses stock springs? I think he picked up about ~20hp over a bolt on car.
Should be a good race against a bolt on c5.

You guys have fun...wish I was close by ;)

What ...not having fun anymore! I wont have tires till next year sorry... I dont think I am gonna need them anyway.

Nice, set it up then......and let's have it.

Or are you too much of a sally.

Oh, and by the way, a C5 is Vette....not a Camaro. :gay:

It's all junior high in here, how old are you guys? :)

Like I said we need a 5th Gen Camaro shit talking section. Maybe a subsection of the Drag Racing section.

Old enough to finance a C5 and fifth gen lol this is Howard cosel welcome the the Internet drag racing finals. We have a bolt on C5 vrs a modded 5th gen. The fifth gen out weighs the C5 by a mere 400 pounds. The driver will have to make up for that. The C5 has his shit talking to the floor and it's off.......... LMAO we need this on video fellas:secret::gtfo::burn:

If the 5th gen weighed 3600 lbs. I'd still have one.

:corn: this is what im takin about!

What I dont understand is if YOU had something to prove... YOU seen me at the track, why not come over say whats up and ask me if I wanted to run! I would have done the same, if I knew you had some kinda unspoken issue with me or whatever! We could have done this already, I already told you I will race you... youll get the call next time I go. Want to show how great you are, show up with stock tires, my little cam makes up for the wieght difference thats about it, a header and tune C5 vette should be running mid 12s all day on stock tires, you need tires to beat me thats not saying much.

I'm done bickering.

See you at the track hoss. :usa:

What you scared, bolton c5 should be a mid 12 car easy without rubber. You want to show me what's up do it without the drag radails, that's as fare as it gets.

My 12 1SS weighs 3840 wouldn't take much to get it to 3600. It traps 111 bone stock with a bit of tinkering 112 shouldn't be a problem. With a set of 4.33s mid 12s easy

I've already been mid 12's with a 423 rwhp 5th gen. It took me ported TB and intake, U/D pulley, headers, catless mids, SLP mufflers, Roto-Fab CAI, Spohn toe link and trailing arms and a Dyno tune. Last Sunday my Vette did almost the same ET at 1 mph faster with a basic tune, corsa CB that was on the car when I bought it and an ET street radial. I'm probably close to 100 rwhp down in the Vette. Weight is a killer on these cars.

My car was running 12.6-12.7 at 111-112 with just the headers, no tune, no intake, nothing else! My car is definetly harder to drive now... there is no way his header and tuned C5 vette cant run mid 12s without tires, he wants a real race and let it go down to driving then he will run me on street tires. If not, hes scared he cant drive... my C5 vette went 12.9s with nothing but a muffler delete.

He already said he's done bickering and he'd see you at the track. What more do you want?

I am not bickering, I issued him a fare challenge.

:punch:

Just make sure there is video when you two race.
