I like your set up, it's well thought out with excellent parts It ​​​​will be more fun and satisfaction spanking folks in a great running HCI 02 WS6 than an 06 C5 Z06.

Maybe consider one change to the exhaust either a a pair of electric cut outs off of the headers or true duals for a better shot at 450+ whp on a Mustang. If that ORY has a 3 inch mid pipe / I pipe to the catback that's going to hurt probably 15-35 whp with that excellent set up.

​​​​​​As is - 425 whp on an honest Mustang dyno & 450 whp on an honest DynoJet

Free flowing dual exhaust like Speed Engineering or dual cutouts off the headers
​​​​~450 whp on an honest Mustang dyno & ~475 whp on an honest DynoJet

Just my thoughts, I hope you exceed your goals by at best 10+ hp.

Thanks for the kind words and insight ......there is no cat back it's just 1 7/8 LTs to 3" ORY to magnaflo muffler. I have truley thought about the exhaust cutouts . And considered the true duals idea but car will be lowered soon .....But TBH I dont want to spend any more money haha

I still have Konis and stranos going in and want strano hollows to compliment .

I've always wanted an Ls7 Z06 haha , but then again.....I've always owned f bodys ......

That's an awesome suspension set up in the works with the Koni/Strano/hollow sway bars for your WS6. Would love to see a picture of the car and Mamo top end. Sound clip?

LS7's are definitely sweet & C6 Z06's rock.


Off topic briefly - Close friend, 30+ years of fbody's had several hot cars, blew off Sam Strano as being an expert at suspension. One day he saw a white Z28 burn up a road course. I quote "..that Z28 corners like no 4th Gen I've ever seen in my life!!!" Later he meets the driver and asks questions etc. Strano's former white Z28 with the new owner he said

Sam suggested an excellent set of roto-joint adjustable RLCA's as my TA's first real suspension upgrade. Aligned the car, they helped get the thrust angle correct. Keeping Bilsteins and getting Strano springs & hollow sway bars too. The spending does get old

Yes my other thread has photos of car .
That's the thing about the ls7 C6 z06 they are corner carving ground pounders with nuts that hang to the floor
Wife hates fbody .........wife loves Z06 ........

I too have spoken to Sam , real cut and dry dude that knows his **** . I got a great deal on the koni sports/stranos from a member here .
....... Hollow sways , lca, adj pan hard, mwc sfc, are in my crosshairs .......and some new rims ..... probably flog it then for my unicorn .

I agree the Y pipe will be the choke point. Cutouts will do wonders

For me it's just the whole thing of spending that money to essentially damage it . ? idk you fellas are definitely swaying my thoughts I've been looking at the SE duals the exit pipes look like they're at a goofy angle .......looking at TSP as well

The heartbreaker is technically a Dyno Dynamics, not a mustang dyno.

You're probably looking at 410 on a Mustang Dyno.

They state in there shop and on their website it's a mustang im just going off that .

theres a trans am on YouTube making 399 with LTs , ported ls6 intake ,ported factory heads, slp lid and a 227 / 234 cam . Im seriously hoping I make more than 11hp over him .

Average RWHP for a FULL bolt-on + H/C/I LS1?

After reading this thoroughly theres guys making 390 ~420 rwhp on cam and bolt on m6 cars w factory heads ..........ported factory h / I with a cam .....but I know a guy can take it with a grain of salt
