so got my car back from having d1sc installed and long tube headers with magnaflow cat back and car made 450 rwhp w some belt slip on 8 rib setup the procharger pulley size is 4.50 anyway when i drive the car with both windows down im getting alot of exhaust fumes and it smells very rich and im kinda getting a little light headed would this be cause by a bad tune?? my car is being dropped off wednesday to slowhawk for him to check things out but i dont believe i have an exhaust leak this cant be normal right ??

 

is the exhaust dumped before the rear end? is this a new exhaust setup? is the car filling with exhaust when you're moving or when you're at a stop light?

 

 

It may be all the crap burning off of the new mods. Did you go catless with dumps?

 

catless and the exhaust is out the rear w no dumps also i smell it more at a stop light but when i rode around in it the exhaust started getting to me
