So Swervo, did you officially wave bye-bye to California? There may be hope on the horizon for us out here..

SmogTips.com - AB 2289 - Smog Check Law California. No more tailpipe smog test. Elimination of tailpipe smog check testing for 2000 model vehicles and newer.

With a proper tune, who knows. Maybe a beast like yours can be legal!
I'm still here in the states til May.

That's not too bad. That's kind of like what NC does. I still won't pass the visual lol.

I also have the Bassani catback on my GT and was looking into buying a set of Bassani long tubes.
How do the long tubes bolt up on to the catback?
By any chance do you have a pic after the install of the longtubes?

It bolts right up to the x-pipe. You just pull out the adapters that were used to attach to the stock catted pipes and the off-road extension or cats will slip right in to the x-pipe and held in using T-bolt clamps.

Did you prefer the studs or bolts? I hear allot of guys re-use the factory studs when they install there headers.

We used most of the factory studs, but pulled some for ease of install and used the supplied bolts for those.

Got you! I just found them on Lethal's website but are they only available in 1 3/4" and would it be much difference not going to the 1 7/8"?

I dont think it would matter too much if your hp goal is reasonable. It might be a restriction at some point, but not sure how high that point is right now. lol.

I have the 1 and 7/8 primaries running into 3" collectors. My car was used for the design and fitment by Dyantech Engineers. I spent several hours around the shop, and their thought on 1 7/8 vs 1 3/4 was 1 3/4 would make more HP in the upper RPM range, and the 1 3/4 would make more Tq in the lower RPM range. This was done before info on the BOSS intake was released, I really think it would open up my cars top end and the loss of low end Tq would be offset by the larger LT's. While my car still makes 25+ HP more than stock at 6500 RPM's, but in relation to the powerband, it feels like it's gasping for air.....

JPC uses 1 3/4 primaries and 2.75" pipes on their cars, including their record setting 9.97 @ 137mph naturally aspirated Coyote. Unless you are using forced induction, Justin Burcham believes the 1 3/4 primaries work better with the Coyote 5.0.
