Anyone know how much whp is lost by going with MHP's catted (200 cell hi flow) midpipes vs their catless version when coupled with their longtube headers? Does the sound level decrease enough to justify the loss in power?

Thanks in advance.

Honestly, the 200 cell cats won't do much for sound suppression. You just as well go catless.

I heard the number "20" tossed around before.

I would go catless.

I see you changed your header preference.

SonnyakaPig

I would go catless too. I'm too afraid of HFC's failing and clogging up. I know it's rare, but it happens.

MHP catless with an Xpipe? has it be done before because I am interested in this setup.

PetroC63

That's an interesting idea. I don't think I ever seen such a setup
mentioned here or anywhere else.

GHAZAN

I got a 3" xpipe off ebay to see if I can fit it anywhere but looks like a custom setup is needed because of the wide mid-pipe spacing. Only place for xpipe would be resonator location and I wanted something closer to the engine.

The Mhp race exhust has an x pipe

PetroC63

Definately a custom job.

I know MBH will make an X-pipe for his headers if you desire.


The closer to the engine would be more ideal.

PetroC63

Does it replace his mid-pipes or the resonator?

GHAZAN

pics of race exhaust would be nice, thanks

Yes, I'm reconsidering my options based on some recent member experience posts. Hoping to join the darkside soon.

Well, if you can wait a little longer I will have some MBH vs MHP header data.

MHP headers and mids arrive tomorrow.

dodger63

Good then we can throw the race exhust on there and.....

BAD430BENZ

i just recently joined the MHP family with tune , headers and mids . i have had them on for a week and i can tell you that the car is a freakin monster . you will be very happy with your results

Dads C63

Go catless with the race exhaust!!
Then all your neighbors will love you as much as mine do. LOL

Then remove the rear mufflers and replace them with 3" straight pipes. Now thats loud!!!!!!!!!! OMG!!

GHAZAN

So they have Xpipe in place of resonator location...i might try it, but didn't want to cut up factory catback

dodger63

You just need headers also then, problem solved

qship5

I kept my secondaries and resonator in place and my neighbors hate me when I cold start it in the morning!

Petro is right, Ideally you want the xpipe as close to the front of the car as possible. Not only does it help balance each bank. It also help to aid in scavenging. The further away it is the less scavenging takes place.

PLS do so! Andy didn't send me before!Thanks in advance!
