dogpoopathome · 09-17-2008, 10:38 PM

no its on my grand prix lol

mr2stealth · 09-17-2008, 10:39 PM

oh well in that case...im not sure.. if it was on the mr2, then i would think just drive it about 50 miles. but im not sure

dogpoopathome · 09-17-2008, 10:44 PM

o. do they sound good tho? well on a mr2

Gairloch · 09-17-2008, 11:29 PM

You're talking about glasspack mufflers? You have to break those in?

mr2stealth · 09-17-2008, 11:32 PM

well i had one on my previous 88 mr2, it sounded mean. but i didnt even know you had to break them in

dogpoopathome · 09-17-2008, 11:37 PM

yea there is fiberglass in them. and when you break the fiberglass it is counted as "breaking it in". and when that happens it sounds nice. my friend has on with no resonator on his 1988 carolla. and that sounds pretty nice

Best way to break in glasspacks on a grand prix is to sell it and drive an MR2! LOL

mr2stealth · 09-17-2008, 11:40 PM

from the day i got it to the day i sold my car, it sounded the same, nice and mean...the exhaust shop didnt even tell me about breaking it in...hmmm

Gunner87 · 09-18-2008, 07:55 AM

Drive for about 20-30 mins. till they get nice and warm then spray water inside the tail pipe... it breaks the fiberglass inside.

yea i did that about 4 or 5 times. it didnt work. i think i might just take a torch to it and hit it with a hammer.

mr2silvertop · 09-18-2008, 08:36 AM

mine took a few weeks of regular drivng. Before, it was so loud your voice vibrated when you were in the car. It has quietened alot since then but still sounds alright. I still wanna change it because I really dont want that much attention from the fuzz.

well do you have a resonator on it?

mr2silvertop · 09-18-2008, 02:06 PM

no, just a regular cherry bomb glasspack. I want the 4 tip monza exhaust.

M.Bailey · 09-18-2008, 05:11 PM

there is no break in on glass packs, the only mufflers that i know of that need break in are high end stainless mufllers because stainless warps so bad when it gets hot so you have to cycle it a few times.

TomsMR2 · 09-18-2008, 05:30 PM

you dont break them in. you dont have to break in any muffler.

M.Bailey · 09-18-2008, 05:34 PM

sorry you must cycle heat through them for a period of time so they dont warp and break
