Anyone know how much lighter the Greddy Spectrum Elite is compared to the good old stocko exhaust? And also if you were to give a db rating to this exhaust with test pipe compared to with stock cat, how much more db would we be talking about when comparing test pipe vs stock cat for the Greddy Spectrum Elite?

 

Dumping your Hi Power?

 

family is getting annoyed by it. The HKS Hi Power will be up for sale soon in the private for sale section after I get the Greddy SE in. I'll make a flyby video before i take the HKS Hi Power Exhaust off and sell it. No one has made a video of it broken in and flyby yet.

 

SE sounds very quiet but perfect with a test pipe, but the pipes are a smaller dia.

 

I'm looking to make nothing over 350hp anyways and 2.75" is enough for up to 500 hp. 3" is for beyond that. I figure a Greddy SE + Test Pipe should still be significantly quieter than what I have now without a test pipe.

 

Where did you get the info from the 2.75" is good enough for 500hp? Not doubting you but I'd love to find out that I can run the Greddy SE and still achieve my 400-450 whp goal on pump gas. I just love the look of that exhaust.

 

I would also like to know where you heard 2.75" pipe is good enough for 500hp

 

I got it from here.

I have the Greddy SE and I think it both sounds great and looks great. I cant remember exactly, but for some reason I remember it shipped at 150 pounds on the ups tracking site?
Might not be what your looking for, but just fyi

 

Is 70MM the ID or the OD?????
