Not sure why. Maybe it's just me. I haven't really been able to open her up since it's been raining bad here since yesterday.

Added a catback yesterday. 3'' stainless steel pipe and a Georloch's muffler. 3'' cutout is welded on right after the I-pipe meets the end of the Ypipe. We did however have to hack up one thing. The catback is used and the guy must've cut off a piece since there was about 4'' missing So I had to use a small piece off the stock Ipipe.

Anyway, the car "feels" slower. Maybe it's a mental thing since the car sounds louder it should feel faster lol. I don't know. Like I said I haven't really been able to go WOT or really beat on the car because it's been wet.

Am I going nuts?

Ok cool

Hey, where in Bensalem do you live?

Vertigo

yes that is normal. It happens to everyone. The sound is playing a role but what is happening is you are losing some lowend tourqe but the fact is after 3000rpm it will flow much much better and pull a lot harder on top end!

I picked up 11 hp and 8 tq at the wheels with a cutout. At the time, my only mods were a ported TB and lid.

yes i gained 11/13 on the dyno AFTER 3000 rpms. it's what you don't see on the dyno that matters. here's my track testing. stock vs open cutout vs bassani tru-dual. your butt dyno is registering correctly.

distance ---stock ----- cutout --- Bassani
60ft ------ 1.987 ------ 2.074 ----- 1.969
1/8 ------- 7.902 ------ 7.912 ----- 7.739
mph ------ 93.20 ------ 93.97 ----- 98.60
1/4 ------ 12.102 ----- 12.080 ---- 11.814
mph ----- 117.12 ----- 118.06 ---- 121.35

its normal to lose that low end pull when u open up exhaust. but it will breathe a lot better up top and therefore pull harder at higher rpms.

I think he's referring to the Hooter's thing. Every last Thursday of the month

As for everyone else, thanks for the info

I'm capping the cutout tomorrow though, cops already gave me **** for it...and it's been on for less than 24 hours lol

the cops gave you ****? Btown cops? man they are the best cops! its when i leave bensalem, i used to get tint warnings and the btown cops said, i dont care if you have tint, just dont give me a reason to pull you over. I had my cutout, never had problems, its not that loud, unless your reving it to 6k next to a cop car.

I saw a solid 1 mph and .10 gain in the quarter mile with a open cutout on my car over an aftermarket catback when it was nearly stock.. I also saw a solid 10 rwhp on the dyno.

IMHO, 'butt' dyno means nothing.

I know the butt dyno doesn't mean much..was just making sure I wasn't going nuts lol

in an m6 its easy to feel the gain, maybe not so much in a a4. Yeah feasterville, usually the cops in not so great districts are hard asses, did you drive by a cop car and he pulled you over? I wouldnt worry about, theres tons of loud cars driving around, just dont get on it near any copper and you should be fine.
