Question for Josh @ Stillen...

[GT-R]

Hi Josh,I would like to know if theres a difference in the cat-back and the axle-back (Horsepowerwise)? Also, on the in-cabin noise, will the cat-back be louder than the axle-back? Cause if there is not much difference between the 2, HPwise and that the axle-back is more quieter in-cabinwise then i will get the axle-back. Also, if i decide to upgrade from axle-back to cat-back, can i purchase the additional hardware from you guys? Josh, can you give me the full scoop between the 2 before i make my purchase?

Thanks,

Tony

Hi Tony!

The cat-back system is going to increase the horsepower the most, as you're replacing the majority of the exhaust piping up to the catalytic converter. The guys going for the axle-back are doing so for the look and improved sound.

The cat-back is going to be a bit louder, both externally and in-cabin, but our systems were designed for an improved exhaust note, not to see how loud we can get things. There is minimal drone with all of our systems, and has an excellent tone.

We do not currently have an upgrade kit from the axle-back to the cat-back, we did produce some extra parts for the early adopters of the axle-back, but they are produced as complete kits and packaged accordingly.

Thanks for the interest!

Hi Josh,First off i would like to thank you for the quick response . Ok, now i get the picture between the two systems. I see that your working on getting us the "Greddies"! ...Now i think i'm going to wait for you to lock down the price on the Greddy's and see which cat-back system to get whether it will be the Stillen or the Greddy's. Would you happen to know when we can start pre-ordering or actually ordering the Greddy's?

Thanks Josh,Tony

Hi Tony,

The price on the GReddy's is the final price, that's the lowest I could get it down to. We are taking pre-orders now, and have a purchase order into GReddy to get them the minute they are available. First come first serve on the orders we receive, we'll ship in that order.

As far as the STILLEN systems, those are in stock and ready to ship today.

The two kits are pretty different styles as far as exhausts go, it's just a matter of your preference..

what are the 2 differences in exhausts?

[johnny_d]

sound?

[dldjros69]

is that it, sound?

i guess the stillen is louder

[Team STILLEN]

The sound will be different, the GReddy is going to be louder, as the STILLEN was developed for tone, but also to not be a loud, droning exhaust (not saying the GReddy will be, I have not heard it obviously..)

Also the physical appearance will be different, the GReddy has a titanium tip, which is also single wall, versus the STILLEN being stainless steel, and a dual wall tip, etc.

Does anyone know who usually puts out more power, or have a guess on which exhaust puts down more power. Referring to Greddy and Stillen

Hi Josh,I ordered my stillen cat-back exhaust and and i'm very excited for its arrival, my question to you, does it come with the additional hangers? I have a 3.5 V6 coupe? Do i need to order this part from my dealership? In that way i will have everything i need for the installation. Also, do you know how long it will take for the exhaust to get to Guam? I ordered it through my dealership?

Thanks Josh,

Tony

what size piping did you use for the catback?
