No problem

Also, in all sincerity, I think if you picked up a "take off" Nismo (the one with the H-pipe) at a decent price, you aren't going see much more springing for a different cat-back. Really to pick up more you'd need either headers or at least high flow cats. With either of those you will DEFINITELY need a tune.

With your current mods and OEM cats, a tune might pick some more power, and you could improve throttle response (and shift speed if AT), but otherwise I'm sure you are running safely without a tune at present.

Hey there,

It's hard to say exactly, but probably a solid 10 -15 whp or more over stock at various points in the rev range on a dynojet with SAE correction.

If you search through my thread with all the dynos (search for "proven power dyno" and my username) or look over the dynos in my gallery (most are in "Back in Black") you should be able to get a good idea as several of the dynos are of those or similar mods before and after tuning.

^^you have a lot of nice cars. Back on topic..I like the stillen sound but don't like the y-pipe factor.

I want great sound and perfect volume. Not too loud and not too quiet. I'm too old for too loud and too young for too quiet. :D

Got mine on Monday, safe and sound. Went to a friends house with a lift this morning and installed. Very simple install, no problems at all. Everything fit and lined up perfectly. I got the 12"...

The only thing I would say is many people order their exhausts for their 370's and think its not going to be very loud inside the car. I thought this same thing as I had previously owned a full Fast...

For me, it's not concern about breaking the car. It's just the overall sensation when driving it. More expensive sportscars emit a sense of confidence, poise and control at high RPMs. You look...

I agree that over 6k RPM, it gets a little unsettling. You start looking at the tach thinking "almost redline, almost redline, get ready, get ready, SHIFT!!!". IMO, a high revving sports car should...

I have seen bushings provided as well. Since the bar just twists inside the bushings, I wasn't to worried about re-using the stock ones. They were nearly brand new. I have run the Stillen bars for...

I think the consensus still stands, Stillen for DD street and Hotchkis if you track. I have been enjoying my Stillen for over a year now, DD/street. Paired up with Swift springs and RE-11's the...

I do love how Stillen attacked the 370 and just made everything for it. It's always nice to have one manufact. on your car worth of stuff, ie, exhaust, intake, supercharger, pulleys, ground effects,...
