Hello Guys,

Looking to change my Stainless Work Axleback Exhaust back to Stock NPP with Hooker Crust pipe Delete Kit as I have already cut the Stock mufflers and have to either Clamp it back on or Wield it.....

Does anybody have this on their car? (HOOKER BLACKHEART CRUSH PIPE DELETE KIT) If so, your thoughts on it?

Thanks....

Absolutely a waste of money. The crushed areas are not hurting performance.

I see what your saying instead of welding the factory pipes back together you could just clamp these into place. Why are you changing back from your Stainless Works If you don't mind me asking?

Correct......sh** ton of drone with the stainless works system :-( Also I really miss the rev match blip sound with stock NPP which the car with stainless works axleback is totally lacking :-(

Do you have deletes installed on uour car? If so, howz the quality of the pipes?

I would do it... how on earth could you justify putting the crushed junk back on it when you can replace it for only 130.00 bucks + install? Regardless of performance, it's knowing it's like that that bothers me..

Wonder if it would provide any hp gains for me being supercharged? I heard the primary cats are the biggest restriction, so that being the case probably not. It just looks so damn restrictive being crushed like that. Does Hooker just pull those claimed HP gains straight out of their asses? I remember seeing Mishimoto do a dyno test comparison on a stock Camaro SS, with the crush and without the crush, and there was NO difference in hp or torque.

[SPARTAN sui]

Hooker designed this BlackHeart crush pipe delete kit for the 16-17 Camaro SS to eliminate the crushed, factory mid-pipe that GM skimped out on. By replacing the inferior pipes you will gain up to 12.84 horsepower and 17.28 lb/ft of torque (tests were recorded on a dual mode NPP Camaro). This offers great bang-for-the-buck as the kit costs less than a few tanks of gas.

All marketing BS. Yeah GM purposely ignored that small section of exhaust pipe. That makes total sense. /sarcasm

Slushboxes Are Not Welcome

Also **** you if you drive an automatic. You are not welcome here.

Totally not bothered about any HP gains, thought this would be a nice alternative vs Wielding back the Stock NPP muffler, Perhaps this might give a little more sound? due to less restriction?

Mishimoto did a very well controlled back-to-back of the "crushed" pipes vs. a round mandrel bent pipe and showed zero difference between the two. It's in this thread:
http://www.camaro6.com/forums/showth...exhaust&page=4

Note that they did this essentially as an FYI. They have no dog in the fight, but were probably just curious like the rest of us.

Facts:
Oval pipes flow just as well as round.
Factory oval pipe sections do not hurt performance.
Likely helps ground clearance.

If it just bothers you, then fine, change it. Know that you are only changing them and spending money, time, and effort for your own OCD tendencies.

You asked for opinions and I have one, though. Good luck.

lol....I have no OCD tendencies, I was just curios to know if it adds a bit more sound to the already Awesome Factory NPP.....I am just trying to find a good alternative to Wielding NPP Muffler with something like clamping it.

I think this product's been given less attention than it deserves. One of the lessons drummed into me back in school was Poiseulle's Law- http://hyperphysics.phy-astr.gsu.edu/hbase/ppois.html, where it describes the effect of decreasing the diameter of a tube on the resistance to flow.

The basic idea is if you decrease the radius by half, you increase the resistance 16 times! Not to mention the greater likelihood of turbulence. Just couldn't let that slide. Yes it could be there is no increase in performance- but we're talking about a car company that wouldn't spend an estimated 57 cents each to fix faulty ignition switches- why build two pipes one for auto's and another for stick shifts, even if it just sounds better.

Which it does IMHO. With the NPP, Track mode sounds alot more serious now.
Was able to do it on jack stands on the garage floor- which is another plus.

we build those exhaust and test with the engineers from GM. they no way affect sound or performance in that current situation. By adding more boost/power you will not see any additional gains either by modifying. I cannot speak on behalf of other exhaust on what they do.

An equation is only good so long as the assumptions behind it are valid. In this case, they are not. I would guess some CFD went into the design of that crushed pipe!
