Hi All,

Anyone with this exhaust system? I'm thinking of getting the MTH header but from someone's video of a MTH + Milltek catback, it seemed pretty loud. Is it normal to expect this from a MTH header + any aftermarket exhaust?

Does anyone have a sound clip of a MTH header + stock exhaust?

Hows a video of a MINI Cooper Rally car that we sponsor ?

This from a MTH header along with a JCW catback system....

Hi have a GTT header..nearly the same shape as the mth one,...I also ran a milltek cat back for a while but took it off because of the noise, far too load and way to boomey, i did'nt like the noise, i have since got the stock cat back on and still running full power,there is'nt much to gain from changing cat back except loads of noise and pretty rear pipes

Imho get the header leave the stock cat back, or try a jcw cat back Henry (supercoopers) came to the same results as myself!

Hi Ricky's

Interesting that you are running a performance header with sports cat and standard cat back. Im running a Milltek full system and agree its too boomy, besides the fact that it drones between 3k -4k rpm. Its a great system, performance benefits I feel from the seat of the pants is fantastic. However its pretty difficult to tolerate the boom over long runs and it drowns out the music too. Pretty much contemplating going down the same route you have taken.

The question is: whats the overall effect of installing the stock cat-back + GTT header, the better exhaust flow from the manifold may be greatly impeded by the more restrictive stock cat-back thereby negating the benefits of using the headers in the first place. This may not be the case and the losses may be minimal but to what extent? It certainly sounds like *pun intended* it will sacrifice some power but how much.

Any ideas?

Regards

(btw - hi chili padi)

Hartge · Jan 29th, 2006, 06:51 AM

Hmm, interesting. I'm looking forward to see the result of MTH header+stock catback. Hey mixednuts, do I know you?

Chili, MTH header is the way to go!

(btw - hi chili padi)

I have used the dyno a number of times whilst playing around with the car and setting the unichip, i can say that i hated every part of the milltek the reasons are its too loud,boomy,rubbed and melted my areo bumper, leaked gases that i could never seal up and its mig welded, uses a front silencer that also rubs and the tone is not good, Imo.

Anyway with the Milltek on it ran 255bhp then with standard ran 263bhp...just not on the same day which maybe the difference....I don't want to argue about different days being the cause or about the 8bhp lost was between exhausts....it was just a decider to me to ditch the milltek.

I know other people love their milltek, thats great its all down to choice at the end of the day.

It is interesting though that Roland at GT Tuning has tested a Scorpion that has more back pressure than a stock cat back

All I know is that i want a Tig welded 3'' stainless cat back system that only has one silencer at the rear and one at front that does'nt rub and sounds great all this with only .5psi back pressure....is that too much to ask for...Maybe so, but untill that is out their my standard cat back is staying put, people are proberly thinking ' why have'nt i used a JCW one'....i have'nt because i thought the milltek was of a similar sound and its still mig welded, why have a stailess exhaust with mig welding uses stainless/mild steel composite wire...which rusts first!

Imho, i dont think the standard cat back flows any less than the jcw one and i still think its the header that counts.

If i was to try anything else on the exhaust side then it will be the one ball surgery idea but how loud will that be?

Hartge · Jan 30th, 2006, 04:56 PM

Oneball? It's not loud and the sound is lovely,lots of pop. Good idea for those who are looking for decent exhaust sound. I think it is best to have header+oneball...

Chilipadi · Jan 31st, 2006, 05:24 PM

Yup, I'm going for the MTH header plus stock catback. Will only decide if I want to do the oneball once I've fixed the header and feel+hear the difference.

Hartge · Jan 31st, 2006, 05:27 PM

You are in Jakarta?

MixedNuts · Feb 2nd, 2006, 03:29 AM

Rick

Thanks for sharing your experience. The variables do not make a diffence to me at this juncture and your opinion is duly respected.

I swapped the Mtek cat-back to stock a few days ago. Certainly feels I've lost a few pounds of torque but again subjective due to variables and sounds. I received an email from Mtek that suggests if full system is too loud to use the std manifold and Mtek cat-back tho.

Thanks again.

Hartge, yes we prolly know one another.

Regards

Hartge · Feb 2nd, 2006, 04:13 AM

Bro, I wonder why they suggest such. Wouldn't it be better to use the milltek header with the stock catback? Or maybe they are just trying to help to reduce the noise? As for more power and torque, Milltek header+stock back is better. Just my 2cents.

Yeah, i agree with you, there are too many variables...but My opinion is that milltek are miles away by suggesting fitting the standard manifold back on, My manifold definatly made a huge difference in both torque and top end power, one of the best mods i think

Hartge · Feb 7th, 2006, 11:57 AM

So anyone with MTH header+Stock cat back??
