I have stock muffler and catless dp from CIA

Cold start ups are single propeller airplane, once warmed up though; it's how it should have sounded like that stock.

Catless DP and Muffler delete is complete and utter garbage. You are one of THOSE guys with how loud it is. I drove like that for 10 miles before I welded my muffler back up - EMBARRASSING.

My motto - better to be quieter and quicker than louder and slower.

 

It's not really overly loud, especially when it idles it's quite nice, it's only loud when you really get on it, when it should be.

 

i cant wait...i have hahn catless in shipment....
but hafta wait till spring to listen to it

 

Wanna install it on mine and test it out while yours is in storage

 

Should caps lock the LOUD in your sentence - LOUD as in noise violation kind of loud. Different folks different strokes.

I wanted something that sounded good when cruising around nomally; not just at idle like catless and MD. Catless and MD didn't do it for me though, too loud overall.

 

It's only a little bit louder than a regular muffler delete, so it didn't seem like too much of a transition. I heard a catless dp with stock everything else on reign1's car, and I did not like it at all, idling or while driving.

 

if my car was fkd and it was because of that and not the winter...
I would do it.

 

/\/\this = wrong...i drove around with ONLY a catless downpipe for almost 6 months and never threw one code...even autocrossed and drag-raced a few times with no CEL

 

The only thing LOUD is the cold start.

Here is the cold start vid and I'll try to get some drive by's tomorrow
