Re: 305tpi new cat w/ chambered muffler

Looks Good. You need to get a better video though! Maybe one with a WOT drive-by, or some higher revs at least.

How much did that whole system cost??

Re: 305tpi new cat w/ chambered muffler

Thats a little steep on the install i think, but I am sure it was well worth it to you!

When you get another vid, you should get one of your brothers car too! I wanna hear that side exit.

Re: 305tpi new cat w/ chambered muffler

That's got a pretty good idle note. I can't really tell on the throttle notes, I need a drive by and or better quality video. So far from what I hear it sounded pretty "meaty".

Re: 305tpi new cat w/ chambered muffler

Hey, Cali? I noticed you had another 2 videos of your car on youtube? Are those with the powerstick too, or something else?

I really like the "New exhaust TPI" video, where the camera is on the ground behind the RR corner of the car! That sounded killer.

Re: 305tpi new cat w/ chambered muffler

So I am guessing your brother's sidepipe sounds kinda like those videos, huh? I really need to get my muffler off one day to see. I think I need a can of better penetrating oil, like PB Blaster or something. I will soak it in PB every day, eventually it will loosen the rust lol.

Re: 305tpi new cat w/ chambered muffler

Why would you get 2.5" pipe? Was the 3" that much more expensive?

Everybody runs 3" on these cars, it would have been fine.

Definately a good sounding exhaust--I especially like the mid RPM range growl on that drive by.
