I have a 91 t/a with a 305 tpi.

I've just purchased edelbrock headers w air tubes and a 3" y pipe. Also a flow master 80 series w/3" inlet and two 2 1/2" tail pipes. I'm going to run a strait pipe from the 3" y pipe to the 3" inlet of the muffler.

The strait pipe with no cat has me worried, I can only assume flowmaster engineered their sound with a cat. Anyone know what this will sound like?

The exhaust upgrade is for a 150 shot. Do you see any problems?

Thanks

 

anyone know?

 

It should be louder at flow better. That would make sense to me. I don't understand where there would be any problems. But I'm no car guru.

 

I just installed some Hooker 2055's with ypipe, plan to install 3"high flow cat and 30 series 1in/1out Flowmaster 3" pipes...

Here are some sound clips from Flowmaster...

Not having the cat will make it a bit louder...

the 30 I'm getting will be a deeper tone than the 80.... also flow better since 1 in 1 out instead of 1 in 2 out... I don't want to see my exhaust, so it will be hidden... another reason I'm goign with this setup...

so not having a cat won't change the sound? only make it louder? is that what your saying

man If my car sounds like the 80 series clip I'm going to wet my pants!~!

 

Right. Also, a lot of the sound has to do with the size of the primaries on your headers. And in a bigger picture, the more cubic inches you've got will add sound, so will good heads and cam. There are lots of factors
True duals will make your car louder.

 

the headers are in!! I'm going to make a sound clip of this exhuast system when I get it installed

 

Congrats! I have the same flowmaster on mine. Sounds good all around. Good idling, and about 1500 RPM the sound changes to a meaner lower rumble. all around a good choice.

 

do u have a cat?

 

Its going to be loud and raspy, basically be a ticket magnet, its prolly gonna sound like crap because of the !cat

 

it sounds fine without a cat.

 

Didn't see this before you got the system on. I'm running 2055's with 80-series, no cat. I had everything the same with the 305 with cat. It's louder w/out, and I'm getting tired of it. No tickets, but too loud when leaving for work at 7 a.m., too loud when cruising to the airport at 70 mph.

It is, however, "quiet" at the track.

 

Well i guess worst comes to worst I'll have a flowmaster 80 series for sale, and buy a magnaflow. If that is still to loud I'll put a high flow cat on. I just don't want to spend 130.00 on a cat if I can help it

 

The cat didn't cut the noise that much. A 3" Bullet, glass pack, or something similar where the cat goes would do more.

 

Well,
This weekend is the big install weekend, any tips on installing headers?

Don't break the bolts off in the heads!!!
