i have a 87 non-turbo i was wondering how much i could gain with the racing beats street header. with the stock exhaust. which i plan to add on to when i get the money.

 

You'll need the presilencer that replaces your cats as well. But upgrading from stock it will be a big improvement. Loud though.

The most restrictive place in your exhaust right now is the cats. After that the mufflers. And then the exhaust manifold, but with stock injection you wont gain much by swapping in headers.

If you want to keep the car mostly stock, id consider just getting some kind of a high flow cat replacement like the bonez one, thats where all the power will be gained. If the cats are in good shape you could even just take them off and bash the center out of them and save money for some nice RB mufflers. It sounds trashy but you'd be suprised with the results.

 

the guy that i bought the car from just replaced the cats. i want to gain power but i am not will yet to rip it apart and port it out. i don't care that it is loud. i live in a county that doesn't have emissons testing but i am planning on going to school in mankato MN. so i don't know there laws, so i am going to save the stock system. how much has some one gained from a RB complete system front to back?

 

Hey, I live in Mankato!

Noise violation laws here are posted and you will get a fine if you are wrapping on it.

The RB system seems to be the benchmark of it all. 5-25Hp maybe from a full exhaust? I haven't seen back to back numbers.

 

thanks are you going to school there?

 

and is that within city limits or is it a state law

 

Sure am, I'm at SCTC. At school I got a narly green SHO.

Going to the tech program?
