Everyone talks about them, then where can I get them. Jegs i only see 3, 40, 50 and 70. I ahve a 92 305 TBI, which size muffler do i need to get. Since the car doesnt have true dual, only oone muffler is required and they will only send me one right? Also, is there any way to take off the single cat and replace it w/ another pipe, where can I get it if so. I dont care if its not legal, I want that heart pounding muscle sound. Any help is appreciated.

 

get a catback. I wish I did. Save the $70 the muffler shop would want.

I just had a 80 series and all new pipe from the cat-back put on at a cool shop in town for a grand total of $267. Thats brand new 2.5" I-pipe, 80 series flo, custom made tips, a couple of hangers (old ones were broke), and labor. For the quality of the work they did (all high quality welds n stuff, no clamps) it was well worth it over me n some buddies clamping it together on jackstands in the driveway, plus much less of a PITA. The cat-back kit that i would've ordered from summit was like $320, so it even saved me $$. And i definately picked up some power, it actually still pulls past 4K now. The sound is not that loud, but very deep at idle and not really hollow at all since i still have the cat. Basically the cool "EFI performance car" sound. I've heard they get louder over time, we'll see, i don't understand how its possible since theres no packing or anything to burn just chambers... but thats what everyone says.


As far as a "heart pounding muscle sound," just ditching the cat and putting on a flow will not do it. It will sound very hollow and kinda crappy without the cat actually. To really get the "feel it in your chest" rumble, what you need is more power not more open exhaust. Even with no muffeler, a 305 dosen't have that sound or feel (i know 2 people who ran that way, one sounded loud but cool the other sounded like shiznit)

Tas, I have the 80 series and need the Dynomax I-pipe you desribe in your sig. What were the prices and where did you get them. I tried the Dynomax site but it wasn't any help. Why do you have 2 part numbers? What size tubing?
