My Greddy don't like the cold
 

I got the Greddy EVO and in MN it's cold right now and when I start my car and start driving it rattles like a mother but as soon as it warms up it's fine.

When did you install it???
 

If it's pretty new, you should retighten the bolts. I think alot of stuff you do to your car (like exhaust, suspension, wheels, etc.) should be checked after 500 miles to check for LOOSTENIN'!

Trust me it's not that. When I start the car it rattles when it warms up it stops rattling. expand and contract the muffler used lock washers.

i experienced the same thing in my 87 max....the catylitic convertor was shot....the honeycomb was busted.....i know the two cars are very different, but it sounds like thats what it is

i don't think it's the muffler..it's probably more motor than the muffler>>cold start...rough idle...vibration...

but this is just my guess..:)

No it's the hangers. I left at four in the morning and I waited to warm up the car and I moved the muffler around and pulled on one hanger and the rattling stopped. Still don't believe me I guess I will video tape it and post it.

it's ok...we all believe u..:D
