MHP header/ Slip in Silencer Inquiry




1) Is the silencer that Superlubricity installed in his own car from MHP or his own fabrication?
2) Can I install the MHP headers/mid-pipes allow for 200 or 300 cell secondary cats? Will this method eliminate droning or the "too loud" factor?
3) Those who have installed the MHP headers...What do you guys think?
4) Superlubricity...Can I inquire with members here about pricing? I don't want to violate TOU or seem like I'm advertising. I just want to make sure a deal is a deal afterall.
Thanks Again!
2. Yes, there will be some sound reduction as well as power. No one has ever claimed MHP droned.
3. Most people will say some version of "awesome or the best"
4. PM members who have the set - super, even money, harrower, etc or call.email MHP yourself.
where my dogs at?

Thanks Ghazan! I'm not too worried about a slight reduction of power as it appears they make quite a bit of power as it is already. You're right about people not complaining about the MHP droning, but they also never said it DON'T. That's why I'm wondering. I'm trying to gain as much power as possible, while maintaining some sort of civility. I'll inquire with those members about pricing. I was hoping to have an open dialogue about pricing as that usually allows for more feedback.
Those were made by MHP. They are very similar to exhaust inserts available for other applications. Google "exhaust inserts" and you'll see how common this kind of silencer is for other applications.
These inserts are much quieter than running 200 or 300 cell cats, especially at start-up. They are like mini-mufflers.
I wouldn't say they are something you can quickly remove and replace because you have to take off the mid-pipes to pull them out. I'm working on my own solution with a local fabricator (using V-band clamps) so I can quickly swap them at the track.
Hope that helps.
As far as pricing to avoid any "advertising" I'd reach out as GHAZAN suggested to a few folks who have them.

Thanks Super!
I just want to clear up any questions about silencers vs. 200-300 cell cats. Is it one or the other? Which one would you recommend? What are the pros/cons for the silencers and 200-300 cell cat?
Thanks again
After hearing a car (nrgy's) with 300-cell cats it was just too loud for me. That is why I worked with MHP on an alternative. The inserts are much more civil. It is still very loud but much more tolerable than without.
Note: Cats certainly help the environment/air quality by reducing some emissions. You'll notice this right away if you go catless because your garage will smell like a gas station/race track; something you can't avoid when you go catless.

Pricing for MHP headers is on their website. You can probably negotiate better pricing if you call them directly. If you are concerned about sound, I suggest you wait until you get a chance to hear a few cars with headers in person or at least try to hear as many of them as you can on youtube.

Once they write 1 ticket, a whole slew of tickets will follow. lol I like your setup right now, but not sure about having my garage smell like a gas station. Ohhhhh....the possibilities!
Probably the best compromise for me will be going with K2 hardware.
catless tri-y/LT headers.
Every morning when I come out to start the car before I leave to work
I scan the neighborhood quickly and make sure no one is around for
fear of causing a heart attack.

For 10 to 15 seconds it sounds like a race car but once it idles it is
much more mellow with a slight muscle car rumble. WOT is also very
loud.
Driving around town is pretty normal, slightly louder than stock. As
long as you can resist continuous wot blasts you will not draw that
much attention. I do not have a front plate mounted either and
have yet to be pulled over by any law enforcement.
I started to feel bad that people might have their ears hurt if I stepped on the throttle too much.
But, I'll admit, if I had the money right now, I would be in the market for MHP LT's, in a second. And I would go the silencer route for daily driving.

This could be a commercial.

Does NRGY have any videoclip of his car? I want to hear a MHP car whit catted midpipes.




Nrgy has cats.
Avenger and super are catless.
cek is stock.

I'll make an effort to see if I can get some in car video/audio driving around to hear how my setup, no cats, sounds.. Honestly, outside of the cold starts and WOT, it's not much more than stock.
