I need help with two things.
1- I was on the greddy website and the sp exhaust says for SE models only.(I have a 98 GLE) I emailed them and spoke to a local shop and they both said there are differences between the gle and se that won't let the exhaust bolt on to the gle. Is this true or do some Gle owners have this exhaust on their car.

2- Does the weight and size of your rims have a great effect on your cars performance?

 

1 - It should fit all trims (there were differences between 95-96 and 97-99 models rear bumper lengths and rear O2 sensors locations)

2 - yes... use the SEARCH feature to find some old threads of this discussion.
