exhaust Q

[zthisstang]

Just had my car tuned and made good power with P1SC made 398rwhp 413rwtq.

I have 2003 GT mild mods C&L upper and o/r h and flows.

The question that I have what would it do to my tune if I were to put the stock H back on. I get way to much attention from the wrong people with the o/r h.

For one, your HP and TQ will drop. The other is you would have to get it back on the dyno to make sure it didn't affect anything else.

That can be a PITA, especially if you happen to live in CA with the smog Nazi's running around.

As stated already, you're gonna lose a little of HP but that'd be better then having to pay a big ticket.

You may want to consider buying a set of hi-flow cats and having them welded into the pipe, you can pick up the cats for a pretty reasonable amount if you shop around, shouldn't cost you more than $30-50 to have them installed into your O/R H.
