I'll try to make this short,

The car had bolts on's before i had the whole thing built and it sounded really good. It has a Buschur exhaust on it, and i loved the way it sounded (nice deep tone). I now get the car back and its WAY louder and has a tinny (best way i can describe it) sound.....basically it sounds like a Honda. Not sure if this is due to the tubular manifold or various other things...

Anyway, just curious if i but a Car on the car, if this will quiet it down substantially....and if so how much power (aprox) will if rob be of???

 

I think you mean "PUT a CAT on the car" and "will IT rob ME of???"

Listing exactly what you changed would probably help us to help you.

 

Just get test pipe resonator that should dampen the honda noise but other than that it should work

 

Well, without knowing what you changed it's hard to say. But in general if you removed your cat, added tubular manifold and O2 then it will be louder and resonate more. Another thing is if your engine build restored some compression you might have been missing then it will be louder too.
But as stated above, weld in a resonator to your test pipe and that will quiet things down a bunch.

 

same happened to me after i added a t3 manifold and 35r kit, car sounded great before then after everything was installed it was loud as **** with a raspy sound. But def. due to the tubular manifold

 

Yup something with me because for the t3

 

Bigger turbo always changes the way a car sounds. I LOVE the sound of my car on a 35r compared to my old hta green. Under boost, its def. louder than before.

 

Same here exhaust note changed considerably going t3 from stock frames. Sounds much better now IMO

 

I love the way my car sounds too the tone with the bigger turbo is perfect you can always tell if a Evo has a bigger turbo on the car just by the exhaust tone.

 

I agree with you, OP. A tubular exhaust manifold will give your car a raspy note, however, when in boost and you're "dumping", the extra airflow from the large frame sounds pretty epic .

 

Ya i was half asleep when i wrote that this morning....I'm reading it now and i'm like "wtf did i write".

Anyway the general consensus is because of the tubular manifold….I guess I’ll deal with it, or put a cat on the car.

 

don't put a cat on it...buschur has the muffler that bolts to the downpipe that would replace a test pipe. that should reduce the raspiness. Then you can either leave the bullet muffler out back our use their resonated "SD" rear section. plently of options to change the tone without sacrificing any flow...just don't put a cat on
