Hi there
So the short of it is that my exhaust has been piecemeal over time on my 1.8L
The final setup, for the past year or so, is deleted secondary cat, replaced with hi flow 2.5" res.
Deleted muffler and stock res, replaced with a Vibrant 2.5" resonator.
Out to a 4" tip
I like the exhaust tone, it's really great and has a growl, not a buzz - but performance is AWEFUL!
I have a Trifecta tune and have a big dead zone between 1k and 3k rpms.
WOTuning has even looked at logs and said the diameter exhaust is probably hurting ,but my top end is great.
It IS a great and throttly highway car...but I did my 0-60 today.... 12.4 best in performance mode. ICK!!!!! Makes me sick, and the lag between 1k and 3k feels like about 2-3 seconds. I can't even peel the tires from a stop at a light ;(
I love the tune overall, but it must be the exhaust.
Once my car is above 3k rpms, it pulls hard.
With that said, if I were to clean it up should I:
Scrap all parts and just do a 2.25 mandrel bend with a resonator (or hifh flow muffler) - I likethe TruBendz simple stainless set ups.
OR
Replace only the existing 2.5" tubing with 2.25" - but there will still be two resonators with 2.5" in/outs
Low end really dropped out when I deleted the secondary cat - combined with more 2.5"
I do want headers in time, but I have to fix this low end situation - it's terrible AND dangerous in traffic when my car just doesn't move at 2000rpms through a turn.
Thoughts would be great - thanks!
