Hi guys.
Exhaust setup:
-1320 Catless UEL
- High Flow FP
- Custom catback
I am experiencing bad exhaust smells in cabin when driving hard OVER 4k.
Street diving is fine, but driving on the highway is rough, especially merging on from the main road.
Here's what me and my mechanic did to try and trouble shoot:
1. Car was lifted on hoist and revved up to see if we could feel any air pressure at gaskets.
2. Covering exhaust tips on idle to see if air was escaping out else where.
Nothing!
I'm frustrated because this SHOULDNT happen, especially at 120km/h on the highway, but I simply dont have an answer.
I'm hoping someone does...
