Right now i have a modded z06 catback but mostly run my cutouts. I want to see some other off the wall options

Long tube hearders, high flow cats and no mufflers. Surprisingly civil until you floor it then all hell breaks loose. I had the Ti mufflers on before I decided to go with this set up. After taking them off I went straight to Summit. The difference in power was unbelievable! It made me realize how restrictive the Ti mufflers are!

About how my cutouts are. I really want side exhaust :-)

wallyman424

why?

The Ti mufflers aren't restrictive at all. ECS has tested them on 700 rwhp blower cars and only saw a 7-10 rwhp loss. Cars with straight pipes are annoying. On my race car I've kept the stock Tis and love them.

You must hate all motorsports then.

Use a rear diffuser, loose weight, and looks cool

It doesn't need to be loud as hell and make everyone tone deaf. I'm keeping my stock Ti units on too.

When I'm in the car for 30 minutes to an hour racing overly loud pipes get really old.

You don't need to have the exhaust exit out the side to have a diffuser. Look at the Callaway Corvette GT3 cars.

Now if only someone made that diffuser....siiiigh

That is a good set up and a cool idea though...hummmm

travisnd

Why are you so stuck on a diffusor for a street car? They require a complete re-work of the underpan of the car, full custom exhaust and trans/diff cooling to make up for the loss of airflow. Side exhaust on a C5/C6 requires a false floor and cutting the frame rails.

Are you building your car to any specific race/TT class?

Ti vs no mufflers at all on a 700hp car 7-10 hp loss? I would have to see those test results to believe it.

I agree. Who cares about peak hp. I can even tell a seat of the pants feel with my cutouts off on low end torque

VGLNTE1

Its on the street about 3 days a month. And you dont need to do all that just to add a flat bottom at the rear of the car to get rid of the parachute c5 and c6s have.

AU N EGL

Diffusers that work are individually made

hell go buy a ricer wing and mount it upside down under the rear of the car. Bolt it to the frame.

travisnd

Look at the above threads

This is incorrect. Adding a "flat bottom" to the rear of a C5/C6 does not creat a diffusor in the proper sense of the term.

Not a bad idea

sperkins

That's because you have to.
But seriously, I ran Ti's for a year and loved them too. I removed them after my first Thunder race when I couldn't hear my car. Car made about 4 more hp with straight pipes.
