Custom - 2 each, thats going to add up.

So I have a question then. If you have a system that splits and goes to two mufflers like these G bodys will it be quieter than a single muffler system with the same muffler ?

I was thinking of trying a Dynomax Ultra Flo on one of my vehicals, are they really loud for street car / driver ?

I'm pretty sure that it'll be quieter with the dual mufflers in comparison to just a single muffler.

Is this accurate? On a 3800 engine?

Correct, Todd. 92 SSE with a 'warmed up' Series 2 out of a 95. Big turbo, NOS, standalone fuel management system, HUGE exhaust, Chip, crazy trans build w/modified gear ratio, and on and on......

The 600 errs on the LOW side of caution And yes, it has been dyno'd.

I'd like a vidcap of this on a dyno with the results. This means it would beat Scotts turbo car in horsepower.

And has for over a year. Turtle is old-school, as are all his buddies. He has an endless supply of parts, machinists, semi-pro race teams......the ideal environment and circle of friends.

HOWEVER, because of all the crap ClubGP caused over this, Turtle will not share publicly. Hector and I have seen proof and evidence in the past. For the time being, you'll have to take my word for it.

You should have seen the numbers on the radar gun
Pucker-factor.

Did it beat 202mph or 179?

Neither, but it beat my top speed (before he re-geared). He has a cop friend who clocked him as a favor.

Rogue we joined just after the BIG fun

I've learned a lot though. I've got a turbo 3.8 litre badge if he wants it

OK.. what about performance into the case?? I was originally plannin on going with DynoMax but from what I hear it'* a baffle design thus creating back pressure ( not flo thru design ). and Flowmaster is similar (maybe glass packed?)?? Magnaflow is straight thru design but has raspy spitting sound.. Borla.. well out of the my price I want to spend on muffler. Any input on whether the internet is right or not??
