i have a glasspack but want to take it off and run straight pipe, if i run a turndown after the cat will i have any noticable mpg/power loss? (91 HO)

 

You shouldnt. I just cut mine behind the cat and i didnt notice any difference in performance or mpgs in my 99. Sounds good too

 

ok! to the sawzall batman! >

 

What kind of turn down do you put after the cat? worried about getting exhaust in the cab? ever put an echoe tip right after it??

 

you should use a muffler with a tailpipe. it won't pass inspection otherwise, and the exhaust fumes coming in will be painful.

 

I didnt put on a turn down, i just cut it at a slight angle to direct the exhaust to the side. I have been running it like this for about 2 months and havent had any worries about exhaust in the cab, but i almost always ride with the windows open, if that makes any difference. I just got it inspected right before i cut it but i plan to install a new highflow cat and a flowmaster muffler in a few months

 

Theres no inspections where i live

 

just got back from chopping it i like the sound, but i think its a little less torquey :\ maybe its cuz im used to driving without doors though

 

what kind of chop did you do? got any sound pics?

 

Go to youtube and search jeep cherokee straight pipe, theres a few good sound clips

 

Just put a muffler on it. They are cheap enough and come winter time when your windows are up you won't have to inhale fumes.
