GReddy Spectrum exhaust Dyno?
 

OK I did a search and I have not seen one Dyno on this exhaust. So I know its a little louder than the Stillen. What #'s does it put out?

I have been looking for this information as well. Someone has to have a dyno pull?

I love this exhaust, but why there is no information about it like Dyno Sheets or weight?

From the pics its seems it got better quality than a lot of cat backs out there!!!

I'm also interested in this but there's so many exhausts out that don't have any good dyno information...

I am told that G-Reddy does not want this info to be public. And I am also told the gains are not up to par with Stillen/FI. You do the math.

I love the sound but I don't want to drop that kind of cash for the sound alone.

Someone buy this exhaust. I will help install the exhaust and get you cheap dyno pulls if you drive to South Carolina.

Here's a vid of my homie on Guam who is running this exhaust....As far as Dyno numbers are concerned we wouldn't know since we no longer have an operative "Dyno Shop" here on Guam anymore....

Hit him up on the forum since he's a member (Simota)....I know that he did tons of research on the exhaust before he bought it and he will be able to give you some insight...I do know that his 1/4 mile time decreased a bit when he had this exhaust installed.

Sounds nice. The Stillen seems like it's at least as loud...and it definitely sounds just as good. Proven HP gains too! :tiphat:

Spectrum
 

I have the Greddy Spectrum Elite with the Berk HFC.....love it...will be doing a dyno run this weekend will keep you posted.

Rumor has it???? that with Spectrum & the Berk approx. HP gain 20 whp??

I will keep you posted

please keep us posted as i am to interested in this exhaust

BTW...he has this exhaust paired with the Stillen HFC's

I hope you're joking. Well if a company want to sell exhaust BUT don't want to dyno their exhaust, I'll take my business elsewhere! :shakes head:

I think you need to dyno and post it! :rolleyes:

Simota does? That make sense...it does sound a little raspy.

Yup...but this vid was taken before he had installed his "Stillen" shorty headers...Rasp isn't so noticeable now...


I guess were all gonna have to wait for Michael M to get back to us with the feedback from his scheduled dyno this weekend...I'm really curious to know whether all the rumors about this exhaust only producing sound and not HP is really true....
