installed my magnaflow catback and i was a little suprised to the interior noise. Is this normal?

 

I tried Magnaflow (WAY TOO LOUD), then went to Flowmaster 40 series (Still too loud for me), I now have a Flo-Pro. Excellent sound, very tight like a race truck, but no interior noise. I took a trip from Ft. Worth to Austin and back this weekend (600 miles total for the trip). I couldn't be happier. Lucky for me, I know the muffler shop guy...

 

THANKS Where did you get the flo pro?

 

Jay's Muffler shop in North Richland Hills, TX.

He is a friend of a friend... I just had him order one on his weekly purchase order... He charged me $45 for parts and labor to change out the other muffler... each time... Extremely fair in my opinion.
