"4 downpipe will fit between the engine and frame if you get it in the right spot. then it runs back like a normal right side of a dual exaust. has a bullet muffler and turn down at the axle. not bad as for noise.

 

So you basically fit 4 inch the whole way back to rear axel and dumped it (routed where stock exhaust goes)

 

yes. it get's a little tight at the trans crossmember but if you keep it tight it is not to low. and my car has 1" lowering split mono springs.

 

Nice ! Thanks for the info... maybe in the near future you could snap a few pics? Tired of the hater pipe in my 68 Camaro and have to get the exhaust to the rear axel this winter.... would like to run 4 inch to the back... was also contemplating the loud valve route and just doing a single 3 inch to the rear for space

 

Looks great ! Just incase you didn't know the regulator according to NHRA rules cant be mounted on the firewall, just a heads up incase your local track checks close enough.

 

well I got it back together and running good. paint completed and wheeled out and ready for a new driveshaft and a second fuel pump. think im going to go stock tank with a sump as well.

 

Car really looks sharp-I ran a 4" down under my nova, then split it off into 2-2.5 duals so i could
go to the rear bumper (and be quite, lol)

 

I had a 4" split to 3" duals on the ble car worked fine but added a lot of weight. so now I run a bullet muffler and turn down at axle

 

That’s 4” under my Nova and all the way out the back. No fumes inside and quiet enough to be on the phone while driving. Also 1 psi backpressure the most post turbine at 19-20 psi of boost with my 5.3.

Looks like it’s hitting the spring but it’s not.

 

looks good to me.

 

Looking good Mike! Nice job.

How many months before track time? (Unless you live in Florida)
