I saw the setup today. Welds look good, and I was really impressed with how exhaust sounds. It sounds almost stock, and certainly quieter than the aftermarked exhaust the previous owner installed on my car. Great for a daily driver, and for keeping a low profile.

I'm nearly certain my quiet exhaust has saved me a few tickets since I went turbo, I've had many verbal warnings

Same setup as this car, just a lowly 1.6 hehe

Well until the zip ties went on my idle KPA was something like 50kpa. There are lots of small things that are "classy" on that car, now that I have a NB my desire to make the 97 nice has fallen dramatically.

Glad that you stopped by. Sorry I could not take you for a ride. I am happy that a customer has seen that I am making things, and not just taking everyones money.

I have had lots of people ask to change to smaller mufflers and such. I am 100% against that because I really do think a quiet exhaust keeps you out of trouble.

^He's right. You could use a few more inches.

It will keep you from sucking fumes under the car.

Longer tip will also decrease noise inside car.

Sure, but you want the exhaust to completely clear the car to prevent drone.

Drone will find you. You cannot escape drone

I was thinking of going with something like this for tip:

Hollyshiiii that's quite. I like it. Did you port the turbo at all? My carbide bits came in and I am super excited to put them to work.

I have ported the turbo a little bit. Not sure if it will need more porting or not yet, will decide on that once the weather gets nice out and I can actually tune and get some logs.

This is what it looks like right now.

Yeah as has been said, I was mostly concerned with melted bumper and drone.

Here's my port work. Third gear run, I creep from 7 to 8 PSI





The wastegate hole on my turbo was overall about 1/2" smaller diameter than the wastegate flap could control. I traced as much of the flapper landing location on the turbine housing as possible while assembled, then filled the rest in using a socket or something as a tracing template. I enlarged the wastegate hole to within about 3/16 to 1/8" of the sealing edge of the flap, or to the point where it would have ate into the sides of the turbine housing too much. I don't think I added too much exhaust pressure on the gate, because I'm pretty happy with my boost threshold so far.

I was able to get about double the range of the flap by grinding clearance for the rivet head, but I'm not sure my wastegate actuator is able to actually use that range.

I respect a tip that stands at attention like that.

That's really not bad at all. With ebc I'd imagine it could level off easily to 10psi year round no sweat
