Yea i would be really intrested in one also. can i just come in and pick it up instead of you having to ship it over here? i came in once asking about the 350z im a tall chinese guy that just bought the 06 350z

Already have a 3" Y-pipe and am very interested in this exhaust.

Hey guys,

If you want to get on this gb...please paypal $150 to sales@gruppe-s.com so I can reserve you one. Please also include a description of this GB and your contact info.

You can come pick it up if you are local.

Thanks,
Tom

 

whats the price for local pick up?

 

Local is $525 + tax.

Thanks,
Tom

 

Tom, would you recommend putting this exhaust on a turbo'd vehicle? Or is it going to be too restrictive? Also is the 3 inch diameter the inner piping or the outer piping?

 

Any update on a ship date?

James

 

He guys,

This is a 3" exhaust and I would still recommend for FI application unless you have a fully build 400-500 whp Z.

thanks,
Tom

Order placed this morning around 2:00 am .
Can't wait to put them on...woohoo.

 

thanks!

 

i humbly disagree with the last part. if the engine produced 3 times as much hp on the second dyno stock (300whp vs. 100whp), then a gain of 10whp on the first dyno translates into a gain of 30whp on the second dyno.

its just math. it takes a lot less "real" power on the second dyno to get a higher reading.

- definitely SMOOTHER acceleration vs stock
- sound nice , reminded me of NISMO
- great exhaust for cheap bastard like me

 

sweet, i like the way its almost like the stock setup

 

actually.. the exhaust is hanging very low. too low which i am afraid if my car was drop 2" more , it would drag when the car is going up the incline for sure.

 

It's actually not that much lower than the stock or Fujitsubo system. The main thing that ends up dragging usually are the tips, which is true of almost any exhaust system, rather than the cannister itself.

i really like the helix and its a lot cheaper than the nismo and fujitsubo.. my only concern is basically how it .. at least looks alot lower. would i have to worry bout speed bumpbs etc if i have stock wheels and suspension? i had a low rider before and don't want to deal with that again.
